Glial cells surround and support the neurons. V. Muscle Tissue . These tissues are made of elongated cells, are excitable and can contract. Responsible for voluntary movements. These cells are long and cylindrical, and when bundled together form fibers, which in turn are sheathed into a muscle.
Skeletal muscle is striated.
Involved in involuntary movements. Smooth muscle is not striated. Epithelial Tissue - sheets of cells Located on the outside of the body and lining body cavities. Important in surface phenomena such as lubrication, maintaining moist surfaces, diffusion, absorption, transport, protection, support, secretion. The shape of epithelial cells is used as a means of classification.
