There are three types of muscle tissues: skeletal, cardiac and smooth. Skeletal muscle is voluntary and found along the bones of the body. Contraction of this muscle type results in gross movements of the body. Cardiac muscle is found exclusively in the heart and contraction results in the expulsion of blood from the heart. Smooth muscle is found in the internal organs and results in the movement of food, air, and blood throughout the body. Nervous Tissue Nervous tissue receives information from the environment, processes that information, and initiates a response, if required. The cells that do this important function are neurons . A second cell type found in nervous tissue are glial

Nervous tissue is found in the brain, spinal cord, and peripheral nerves. The Integumentary System The largest and heaviest organ of the body is the skin. The skin is formed by an outer layer of stratified squamous epithelium and an inner connective tissue layer . This cutaneous membrane sits on the hypodermis , which is not technically part of the skin. Although all skin contains these layers, different parts of the skin have a variable thickness of these layers. Thick skin generally contains no hair follicles or oil glands and often thickens further forming calluses on the hands and feet. Thick skin has a greatly increased outermost layer of the epidermis ....
