Human body tissue consists of groups of cells with a similar structure working together for a specific function. There are four main types of tissue in a body.
Muscle Tissue
Muscle tissue is made up of excitable cells that are long and fibrous. These cells are ready for contraction, or the activation of tension in our muscles, making it possible for us to move our body parts.
Epithelial Tissue
Epithelial tissue is made up of epithelial cells, which can be flat, cuboidal, or columnar. They are joined tightly together, making a single or stacked continuous sheet. Epithelium makes an excellent protective cover for the body, in the form of skin. Epithelial tissue can also be found lining some internal cavities and organs.
Connective Tissue
The main jobs of this tissue are to hold our body parts together and providing support.
Nervous Tissue
Nervous tissue is found within the nervous system and is made up of specialized cells which are known as neurons. Like electrical circuits, the nervous system transmits signals from nerves to the spinal cord and brain.
