Nerve Tissue

Function: processes sensory information from sensory organs and responds with motor instruction to the

body muscles and glands.

Nerve Tissue

Classification:

Neurons: cells responsible for retrieving, interpreting and sending the electrical signals of the nervous system.

Neuroglia / Glial cells: support cells that surround and wrap neurons
