Human Cell Components

Necleolus:
The round granular structure within the nucleus of a cell, and composed of protein and RNA. Nucleolus is involved with ribosomal RNA synthesis and formation of ribosomes in cells.

Nucleoplasm
The nucleoplasm is a highly viscous liquid that surrounds the chromosomes and nucleoli. Many substances such as nucleotides (necessary for purposes such as the replication of DNA) and enzymes (which direct activities that take place in the nucleus) are dissolved in the nucleoplasm.
Mitochondrion:
Spherical or rod-shaped organelles found within the cytoplasm of cells, and are referred to as the “powerhouse of the cell since they act as the site for the production of high-energy compounds (e.g. ATP), which are vital energy source for several cellular processes.
Nucleus:
The large, membrane-bounded organelle that contains the genetic material, in the form of multiple linear DNA molecules organized into structures called chromosomes. The major functions of nucleus are to maintain the integrity of DNA and to control cellular activities such as metabolism, growth, and reproduction by regulating gene expression.
Cytoplasm:
It is the jelly-like substance in a cell that contains the cytosol, organelles, and inclusions, but not including the nucleus. The cytoplasm is where the functions for cell expansion, growth, metabolism, and replication are carried out
Ribosome:
A minute particle composed of protein and ribonucleic acid (RNA) that serves as the site of protein synthesis.
Golgi Complex:
Golgi apparatus packages proteins inside the cell before they are sent to their destination; it is particularly important in the processing of proteins for secretion.
Smooth Endoplasmic Reticulum: Tubular in form and lacks ribosomes. Its functions include lipid synthesis, carbohydrate metabolism, calcium concentration, drug detoxification, and…...

...Why We Study the Cell and Its Components The cell is the basic unit of all living organisms. Some organisms like bacteria have only one cell while other organisms are multi cellular. It is important to study the cell and its components because it enables understanding of our own life and opens up windows of opportunity for the future generations. Understanding cells and their component functions allows for better understanding of disease and the possibility of cures or better treatment options. Biologists study the cell in healthy and diseased states to develop new vaccines, medicines, plants with improved qualities and to gain a better understanding of how all living things live. The study of cells and its components is also helpful in solving crimes through forensic science. In biotechnology, the study of cells is used to clone plants and animals, and with time possibly for the production of organs. In studying cells it is important to know what organism the cell comes from. There are two types of cells, the prokaryotic and eukaryotic. The prokaryotic were the first type of cells to evolve. Prokaryotic cells do not have a nucleus; bacteria are the best known prokaryotic cells. Organisms that contain eukaryotic cells include fungi, animals, and plants as well as some unicellular organisms. The eukaryotic cell is much bigger and contains membrane bound compartments where metabolic activities take place. The components of the cell include, plasma membrane,......

Human Embryonic Stem Cells

...Introduction Human embryonic stem cells (hES cells) are currently discussed not only by the biologists by whom they were discovered but also by the medical profession, media, ethicists, governments and politicians. There are several reasons for this. On the one hand, these ‘super cells’ have a major clinical potential in tissue repair, with their proponents believing that they represent the future relief or cure of a wide range of common disabilities; replacement of defective cells in a patient by transplantation of hES cell‐derived equivalents would restore normal function. On the other hand, the use of hES cells is highly controversial because they are derived from human pre‐implantation embryos. To date, most embryos used for the establishment of hES cell lines have been spare embryos from IVF, but the creation of embryos specifically for deriving hES cells is also under discussion. The most controversial variant of this is the transfer of a somatic cell‐nucleus from a patient to an enucleated oocyte (unfertilized egg) in order to produce hES cells genetically identical to that patient for ‘autologous’ transplantation (so‐called ‘therapeutic’ cloning); this may prevent tissue rejection. The question ‘Can these cells be isolated and used and, if so, under what conditions and restrictions’ is presently high on the political and ethical agenda, with policies and legislation being formulated in many countries to regulate their derivation. The UK has been the first to......

Complexity of Human Cell

...Assignment on Complexity of Human Cell The universe is alive with movement: moons rotating around planets, planets orbiting stars, gaseous rings rotating and expanding, meteors and comets soaring through space at great speeds; and all the while the entire universe are expanding at an accelerated rate. Thankfully for us, it is not a dance of chaos; gravity governs the dance, allowing stars, planets and moons to move coherently to one another. In like manner, there is a vast micro-universe softly humming underneath our skin. As with the seemingly endless varieties of stars, human cells vary in shape and function and there are trillions of them in your body. They carry out the continual demands of the body’s life processes in elegant harmony. The digestive system is just one example of the body’s remarkable ability to assimilate the raw materials from its environment to manufacture all the necessary elements for physiological function. Through digestion, the food you eat every day is broken down into molecules small enough to squeeze through the billions of blood capillaries imbedded in your intestinal wall. The bloodstream circulates these molecules until they enter the intercellular fluid that surrounds the cells. Finally these molecules pass through the cell membranes into the cells. It is here we find a direct connection between what you eat and the health of trillions of cells that make up the human body. Each person begins as a single cell -- a cell structure formed......

Ghrelin Promotes the Differentiation of Human Embryonic Stem Cells in Infracted Cardiac Microenvironment

...Adam Lerman Date: May 11 Ghrelin promotes the differentiation of human embryonic stem cells in infracted cardiac microenvironment Reference: Meijuan Gao, Jin Yang, Guoqiang Liu, Rui Wei, Lin Zhang, Haining Wang, Guang Wang, Hongwei Gao, Guian Chen, Tianpei Hong, Ghrelin promotes the differentiation of human embryonic stem cells in infarcted cardiac microenvironment, Peptides, Volume 34, Issue 2, April 2012, Pages 373-379, ISSN 0196-9781, 10.1016/j.peptides.2012.02.006. Background: Human embryonic stem cells (hESC’s) are derived from inner cell mass of blastocyst of embryos, which are used for in vitro fertilization and embryonic donations. hES cells are used because of their self renewing ability and their pluripotency to differentiate into germ layers. hESC’s are used for regeneration of and organ regeneration of tissues, like for myocardial regeneration to treat irreversible heart injuries. Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor to promote the release of growth hormone. It is unclear is hESC’s can induce myocardial generation by ghrelin after in vivo engraftment into the myocardium. What was done: Adult male Sprague-Dawley rats that were eight weeks old were used. The hESC’s were cultured on y-irradiated mouse embryonic fibroblast feeder layers. The rats were induced with myocardial infarction (MI) by the ligation of the left anterior descending coronary artery (LAD). They used one...

Outline the Functions of the Main Cell Components

...Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the biggest part of the cell and is the part of the cell which acts like the brain. It is not always in the middle of the cell but will be placed within the cytoplasm. In some cases a cell may have many nuclei and these are called multinucleate and are usually in muscle cells. In red blood cells, the nucleus is lost during development and is the only cell that is able to survive without a nucleus. The nucleus includes DNA. Cytoplasm: The cytoplasm of a cell is the material in the inside of the cell which is semi-fluid and is able to flow slowly and all chemical reactions within cells are carried out in there. Complex sugars including glycogen and melanin which is the pigment responsible for skin and hair colour are in the cytoplasm. These chemicals are the basic living materials that a cell needs. Organelles are the various components of a cell with a specific structure and function and are linked to miniature organs. These include: Mitochondria: These are small components within cells that perform different important functions in order to keep the body healthy. They make the energy that cells need to do to work correctly. An example of this is brain cells which need a large amount of energy in......

Cells

...Structures in All Eukaryotic Cells We're going to start with eukaryotic cells even though they tend to be more complex than prokaryotic. But, there is a method to our madness: you are a eukaryote and have eukaryotic cells, so we thought you might relate better. And, eukaryotic comes before prokaryotic alphabetically. Come up with whatever reasons you want for it, but eukaryotes are up first. Tough cookies. Eukaryotic Cell Structure and Function A cell is defined as eukaryotic if it has a membrane-bound nucleus. Any organism composed of eukaryotic cells is also considered a eukaryotic organism. Case in point: You. Biologists do not know of any single organism on Earth that is composed of both eukaryotic and prokaryotic cells. However, many different types of prokaryotic cells, usually bacteria, can live inside larger eukaryotic organisms. Creepy, but true. We humans, for example, have trillions of bacteria living in our colons, not to mention in our mouths and stomachs and small intestines and…you get the picture. Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. Deal with it. This means that all human cells, including those found in the brain, the heart, the muscles, and so on, are also eukaryotic. Here is what one of these little guys looks like: OK, we are slightly impressed. That is a lot of stuff jam-packed into something we can't see too well with the naked eye. All......

The rigid outer covering of a typical human cell, composed mainly of cellulose and lying outside the cell membrane. Definition of Plasma membrane. All cells are surrounded by a plasma membrane. The membrane is composed of a phospholipid bilayer arranged back-to-back. The membrane is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell. Definition of Plasma membrane. All cells are surrounded by a plasma membrane. The membrane is composed of a phospholipid bilayer arranged back-to-back. The membrane is also covered in places with cholesterol molecules and proteins. The plasma membrane is selectively permeable and regulates which molecules are allowed to enter and exit the cell. Human cells have a membrane that holds the contents together. However, this membrane is not just a sack. It has receptors that identify the cell to other cells. The receptors also react to substances produced in the body and to drugs taken into the body, selectively allowing these substances or drugs to enter and leave the cell. Reactions that take place at the receptors often alter or control a cell's functions. An example of this is when insulin binds to receptors on the cell membrane to......

...www.asbiology101.wordpress.com An introduction to the microscope and magnification MAGNIFICATION AND RESOLUTION Because cells are too small to be seen with the naked eye, the light microscope was developed to produce enlarged and more detailed images of cells. The magnification of an image is how much bigger it appears under the microscope than it is in real life, and is worked out using the following formula: magnification = image size ÷ actual size unit metre decimetre centimetre millimetre micrometre nanometre picometre symbol m dm cm mm μm nm pm metres 1 0.1 0.01 0.001 0.000 001 0.000 000 001 0.000 000 000 01 However, magnification on its own does not increase the level of detail seen, it just increases the size. The term resolution refers to the ability to see two distinct points separately. For example, if the resolution of a light microscope is 200nm (0.2μm), this means it can see any two different points as separate objects if they are 200nm apart or more; but if they are any closer than this amount, they appear as one object. THE LIGHT MICROSCOPE Light microscopes use a number of lenses to produce an image that can be viewed directly at the eyepiece. Light passes from a bulb under the stage, through a condenser lens and then through the specimen. This beam of light is passed through an objective lens and then the eyepiece lens. The light microscope usually has a number of objective lenses which can be rotated into......

In Vitro Cytotoxic Effects of Muntingia Calabura Linn. Fruits Against Human Cancer Cell Lines.

...Fruits against human cancer cell lines. Introduction  Muntingia calabura Linn is a plant that belongs to the Elaeocarpaceae family, commonly known as cherry tree. The tree bears small red fruits with enormous tiny yellow seeds. The fruits are so sweety and juicy, which attracts the people to eat. This plant has been used as the Peru traditional medicine in reducing the swell of the prostate gland and alleviating headaches and cold as well as pains associated with gastric ulcers. The fruits and leaves possess the antioxidant activity [1]. Cancer is the major cause of death worldwide, claiming over 6 million lives every year. In the recent years alternative therapies have gained importance over conventional cancer therapies for the treatment of cancer [2]. Chemotherapy is restricted by both intrinsic and acquired cell resistance to drugs. [3] This has necessitated the use of natural products for the treatment of cancer. There are compelling evidences for experimental investigations on the efficacy of plant drugs against cancer [4]. It is known that there are links between the inflammatory and nociceptive, oxidative and cancer processes. The ability to inhibit any of the process will definitely lead to the inhibition of the others [5]. Based on the fact that M. calabura fruit possess antioxidant activity, the aim of the present study was to determine the in vitro anticancer activity of methanol extracts of the fruits of M. calabura against HeLa and HEp-2 cancer cell lines......

Cell Phone and Its Harmful Impact on Human

...Impact of Cell Phone’s Radio Frequency in Children Herzing University Saugat Basnet The development and use of mobile device services in the last decade have hugely increased the amount of radiofrequency electromagnetic wave (RF-EMW). High exposures towards radio frequency (RF) in our daily lives have raised concerns regarding the harmful effects on human health especially on children. Children with cell phone exposure have higher odds of migraines and headache-related symptoms than the one with no exposure. A great deal of scientific and public interest have focused on radio frequencies that alter the brain, somatic and germinal cells in children. Children should be very careful and guided by elders while using cell phones that produce a lot of harmful radio frequencies. Today cell phone is one of the inseparable parts of modern life. Each and every daily activity today is possibly accomplished by the aid of the cell phone. With its reference, we can say that cell phone directly and regularly comes in contact with the vital body parts like head and sense organs. As it comes in contact with vital organs, not immediately but after some long term exposure, it causes severe health problems and in children, it’s even more serious. Children are still developing mentally; therefore, radio frequency from cell phones has a greater effect on them than on adults. It is because children have growing body parts where cell multiplication is active. According to a study conducted by......

Stem Cell Research and Human Transplantation

...Stem Cell Research in Human Transplantation [Name of the Writer] [Name of the Institution] Abstract Skeletal Bone Marrow that is decimated by disease, chemo, or radioactive emission can be refurbished by utilizing stem cell transplants. For certain infectious ailments like leukemia, aplastic anemia, certain inherited body-fluid infections, and some infections of the immune cell, and the stem cells in the skeletal bone marrow do not effectively function the way that it is intended to function. The stem cell is subjected to immunity issues where the recipient body site does not accept the donor cells. This paper will look to enquire the benefits to following stem cell research in human transplantation. Stem Cell Research Introduction Unique functional cells such as for example, a red blood cell start out originally as unspecialized cells known as stem cells. These stem cells have the uncanny ability to keep separating through division and multiplying in culture to produce specialized cell for a specific bodily function. In the context of normal human development, they are best described for their diversity, adaptability and longevity. As the laws of biology dictate, a human being is formed when a sperm cell fertilizing a female egg cell to produce a zygote. The zygote is already specialized in the fact that it is on the way to the formation of a whole individual. Furthermore the zygote, also known as the fertilized egg is tot potent that......
