Muscle System If you enjoy action, then this is the system for you. No matter how still you try to be, there's always a movement taking place in your muscles. Did you know there are over 650 muscles in the human body, and that muscles make up 1/3 of a grown human body? Muscles cover the entire skeleton, and bones can't move without muscles. Flex your muscles and tour this exciting system! Three types of muscles are skeletal muscles, smooth muscles, and cardiac muscles. Skeletal muscle tissue co

Introduction
Introduction Steroids are hormonal substances, naturally produced in the body by the adrenal glands above the kidney and by reproductive organs. There are many different types of steroids and they all have different effects on the body. Some types of steroids have been found to help destroy some types of cancer cells, and can make more effective. This fact sheet describes steroids, how they are given and some of the side effects that may occur. Common types of steroids that are used in cancer t

1.) Three genetic disorders are Down's syndrome, Turner's syndrome, and Red-green color blindness. They are all caused by undesirable genes inherited by normal genetic mechanisms. These mutations are usually recessive because dominant ones usually die. Turner's Syndrome is caused by faulty cell division known as non disjunction. This occurs when chromosomes fail to separate. IN this disorder, the affected have one x chromosome. The effect are an underdeveloped female, mental retardedness, and

Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two

It acts by promoting the effectiveness of several amines (dopamine, norepinephrine, and 5-hydroxytryptamine, which is also known as 5HT and serotonin). It functions by inhibiting their reuptake at the terminals of nerve cells,

One of the most deadly, incurable disease the world is faced with today is the Human Immunodeficency Virus (HIV). There is no none cure yet. Viruses cause colds and the flu. Viruses are microscopic particles that invade the cells of plants, animals, fungi, and bacteria. They often destroy the cells they inva
Active Transport
Active Transport
Active Transport Since the cell membrane is somewhat permeable to sodium ions, simple diffusion would result in a net movement of sodium ions into the cell, until the concentrations on the two sides of the membrane became equal. Sodium actually does diffuse into the cell rather freely, but as fast as it does so, the cell actively pumps it out again, against the concentration difference. The mechanism by which the cell pumps the sodium ions out is called active transport. Active transport require

The cell wall is composed of two layers of rigid, hard cellulose embedded in compounds like pectin and lignin. Pores in the cell wall allow molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth of the cell. After the cell has stopped growing, a secondary cell wall for

For many decade, people have used one form of an anesthetic during surgical procedures. Some people also use some of these anesthetics as recreational drugs, e.g. laughing gas (a.k.a. Nitrous Oxide). The term anesthetic literally means without feeling. There are many different types of anesthesia, but they are usually put into three groups. These groups are gene- r

The inside layer is made of hydrophobic fatty acid tails that repel water so therefore the plasma membrane or cell membranes is capable of self assembly. The fatty acids can either be saturated and unsaturated. Saturated fatty acids have no carbon-carbon double bonds while the unsaturated fatty acids have one to four double bonds between adjacen
