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.
