Animal Tissues

There are four types of tissues found in animals: epithelial tissue,connective tissue, muscle tissue, and  nervous tissue.  

I. Epithelial Tissue

Epithelial tissues line body surfaces and cavities, as well as form glands. The cells of the tissue are  closely connected to each other via cellular junctions and because epithelium is found on the edges of  organs, it  has two distinct surfaces.

II.  Connective Tissue

Connective tissues vary widely in their form and function, but they are all characterized by the presence of extracellular matrix. The extracellular matrix is nonliving material composed of protein fibers and ground substance. The protein fibers are composed of collagen (which gives strength) or elastin (which  gives flexibility).

III.  Muscle Tissue

Muscle tissue is specialized for contraction.  The cells are elongated, and are also known as muscle  fibers. They contain the contractile proteins actin and myosin, which interact to shorten and elongate  the cells.There are three different types of muscle tissue : skeletal, cardiac, and smooth.

IV.  Nervous Tissue

Nervous tissue is specialized for communication and composes the brain, spinal cord, and peripheral nerves. The tissue consists of two major cell types: neurons and glial cells. Neurons communicate with  each other via electrical and chemical signals.
