What Type of Tissue Carries Messages Throughout the Body?

Nerve tissue transports messages throughout the body. It is composed of two types of nerve cells: neurons and glial cells. Neurons are the functional units of the nervous system, while the glial cells help the neurons function correctly.

The neurons transmit electrical signals known as nerve impulses throughout the nervous system. They are primarily made of the cell body, dendrites and an axon. The cell body houses the cell's nucleus and organelles, the dendrites receive nerve impulses and the axon transmits nerve impulses. Glial cells provide neurons with the required nutrients to perform their job.

The nervous system is made of the central nervous system (the brain and spine) and the peripheral nervous system (the nerves in the body).
