John Jay College for Criminal Justice defines tissue as “a collection of similar cells that group together to perform a specialized function.” Human tissue is generally divided into four groups: epithelial, connective, muscle, and nerve. However, the body is a system, and although human tissue...
Long, tapered muscle cells have an intrinsic stretchiness that allows them to change length within contracting and relaxing biceps. Still, as different as these cells are, they all rely on the same basic strategies to keep the outside out, allow necessary substances in and permit others to ...
(b) What each of the functions is? What are the 4 basic structures of a cell? If every cell in your body has exactly the same DNA, why are brain cells different from muscle cells? a. Because they are located in different parts of your body. b. Because different types o...
Often oversimplified like much of fitness, muscle fibers are the stringy, contractile filaments that make up every muscle in your body. There are several different varieties, but generally speaking, you only have to be concerned with two, imaginatively namedtype Iandtype II. Type I fibers are s...
The nervous system of the vertebrate is made up of the nerve cells which are linked to one another and their various receptors and effectors in different parts of the body. It is divided into the central nervous system and the peripheral nervous system. The central nervous system ...

Pacemaker cells are specialized cells that cause involuntary muscles and tissues to contract or dilate. They are found in all involuntary muscle groups, including both striated and smooth tissues. Striated involuntary muscles are found in the heart, while smooth involuntary tissue can be found in ...
What Are the Different Types of Anabolic Steroids? November 6, 2011 If you think about, there are some positive effects of steroids if you're a serious athlete. They help you build muscle and perform more successfully. If you perform better, you make more money and have access to a lot ...
Describe functional and structural adaptations that enable muscle cells, nerve cells and sperm cells to carry out their functions, respectively. Nerve cells and liver cells have very different functions inside the body. Besides shape, ...
Though it's also made of collagen, loose fibrous tissue, it is different from the dense tissue in that it also contains open spaces known as areolae. These spaces are filled with fluid and are found along with the collagen and elastic fibers making up the tissue. This type of tissue can...
