There are 4 basic types of tissue: connective tissue, epithelial
tissue, muscle tissue, and nervous tissue. Connective tissue
supports other tissues and binds them together (bone, blood, and
lymph tissues). Epithelial tissue provides a covering (skin, the
linings of the various passages inside the body). Muscle tissue
includes striated (also called voluntary) muscles that move the
skeleton, and smooth muscle, such as the muscles that surround the
stomach. Nerve tissue is made up of nerve cells (neurons) and is
used to carry "messages" to and from various parts of the body.
