TISSUE
Tissue is a conection of similar cells that usually have a common embryonic origin and which function in association to develop specialized activities.
Tissues are composed of cells and the extracellular matrix produced by them. The matrix is almost nonexistent in some tissues, while in other structures and contains abundant and important molecules from structurally and functionally.

There are four basic types of tissue:
1. connective tissue,
2. epithelial tissue,
3. muscle tissue
4. nervous tissue.
The connective tissue supports and connects other tissues such as bone, blood and lymphatic tissues.
The epithelial tissue provides a covering; as the skin and the lining of the various passages within the body.
The Muscle tissue consists of:
1.Striated or voluntary muscles that move the skeleton
2.Smooth muscle, such as that surrounding the stomach.
The Nervous tissue: is made up of nerve cells or neurons and used to carry "messages" to and from various parts of the body.
