Side By Side Endoplasmic Reticulum
2,193 words... e detoxification processes by which enzymes act on chemicals and drugs to change their structure and reduce their toxicity. The smooth endoplasmic reticulum of skeletal muscle stores calcium ions that function in muscle contraction. The Golgi apparatus is composed of flattened membranous sacs, containing cisternae, that are stacked on each other like dinner plates. The Golgi apparatus modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic ret...

This is maybe the most ancient form of brain surgery known to man: it is called trepanning (from Greek trianon, borer) or trephining (Sabbatini, 1997). This perhaps was the first idea that man can be cured of mental illness by biological exploration. Thousands of years later, psychosurgery was discovered by accident in America in 1847 when...

Spindle Fibers Opposite Sides
534 wordsMitosis is the process of nuclear division in a living cell by which the chromosomes are exactly replicated, the two parts being separated are given to the daughter nuclei. In this process the two daughter cells receive chromosomes that are alike in composition and equal in the number of chromosomes as the parent cell. Mitosis consists of four main stages. Mitotic division occurs in somatic (body) cells. The stages are prophase, metaphase, anaphase, and telophase. In interphase the cell seems to...

Figure 2 Figure 4
1,075 words... tests, including vibration, impact, and fiber retention, were performed to evaluate the strength of the bonds between the glass solder and the optical fibers and the substrate. For the fiber retention tests, standard singlemode fibers were secured to silica substrates with a small (- 2 mm diameter) bead of glass solder using the process described above. Tensile forces were then applied to the fiber leads by attaching weights of known mass. All five samples in this study were able to support ...

Sheet Of Cellulose Nitrate Sheet Of Cellulose Polymers
571 wordsPolymers have been around longer than we have. In fact, polymers are as old as life itself, as all life on earth is based on three types of polymers, namely DNA, RNA, and proteins. But this report is about some of the earliest synthetic polymers, that is, polymers made by humans, specifically, the cellulose derivatives. The very first synthetic polymer was of course leather, a modified natural polymer, an artificially crosslinked form of the proteins found in animal skins. Leather tanning was di...

Current Research On Muscular Dystrophy
576 wordsDuchenne's muscular dystrophy is the result of a defective gene on the X chromosome. This gene is responsible for production of the muscle protein dystrophic. Dystrophin is an integral part of the dystrophic-glycoprotein complex which bears the brunt of the force generated during muscular contraction. When dystrophic is not produced, the dystrophic-glycoprotein complex (DCG) is not present. Absence of the DCG leads to tears in the muscle membrane because the muscle membrane bears the force of mu...

Central Nervous System White Blood Cells
1,504 wordsThe name itself is revealing: multiple, more than one, and sclerosis, which refers to areas of sclerotic (scarred) tissue. Multiple sclerosis is a demyelinating disease of the white matter of the central nervous system. These areas of sclerosis, also referred to as lesions or plaques, occur in the white matter of the central nervous system. Gray matter consists primarily of nerve cells. Axons (nerve fibers) are the connections between the cell body and the muscles, sensory organs, and primary or...

I for one would not like see the day that money hungry business man cut down the last tree for such a now useless object such as paper. Nowadays, with computers, there is no need for paper other than for printing. Paper use can be seriously decreased if we would just accept computers as a superior alternative to paper. If we would start using more Palm Pilot like devices and us...

An Introduction To Fiber Optics Technology
1,471 wordsThroughout time, speed and efficiency in the telecommunications industry has progressed at a rapid pace due to fiber optic technology. In 1979, AT& T revolutionized the telecommunications industry by producing a medium for data transmission which used light, called fiber optic cable. This medium created a bandwidth of 44. 736 Mbps and could multiplex 672 trunk circuits onto one fiber (Cole, 2000). However, this invention was only the beginning of a great addition to telecommunications, one t...

Central Nervous System Peripheral Nervous System
1,508 wordsThe only multi-cellular animals without a nervous system are sponges. They do not have any nerve cells or sensory cells. Despite this, touch or pressure to the outside of a sponge will cause a local contraction of its body. Cnidarians The jellyfish and most all other forms of cnidarians, such as the hydra and sea anemone, are characterized by a nerve net. A nerve net is a series of interconnected nerve cells that conduct impulses around the jellyfish's entire body. The strength of the jellyfish'...

The anatomy of the brain is composed of neurons (nerve cells) and neuroglia or supporting cells. The brain consists of gray and white matter. Gray matter is composed mainly of neuron cell bodies and is concentrated in the cerebral cortex and the nuclei and basal ganglia. White matter is composed...

Physical Science 1 Page
602 wordsBefore we look at insulation we must see how thermal energy moves. There are three ways it moves. The first is by conduction. Conduction is the transfer of energy by direct contact of particles. Heat spreads through out an object till the object is the same all the way around. (Physical Science section 6. 1, page 1) This happens because all particles vibrate unless in an absolute zero situation. These more violently moving particles hit each other. Eventually these particles will vibrate at the ...

Nuclear Membrane Daughter Cells
471 wordsMitosis evolved in complex plants and animals for growth and repair. Mitosis, the division of a cell resulting in two identical daughter cells, prolongs an organism s life by replacing old, dead, and damaged cells. In complex animals and plants, mitosis occurs everywhere, except sex cells. Meiosis evolved in complex plants and animals to increase variation in offspring and to maintain the number of chromosomes from generation to generation. Meiosis occurs in the sex cells of organisms, specifica...
