Muscle tissues are characterized by the presence of elongated cells or muscle fibers that can contract. As they shorten, these fibers pull at their attached ends and cause body parts to move. The three types of muscle tissues are skeletal, smooth, and cardiac.

Nervous tissues occur in the brain, spinal cord, and nerves. They consist of neurons (nerve cells), which are the impulse conducting cells of the nervous system, and neuroglial cells, which perform supportive and protective functions.
