This has been created for educational purposes as a review of muscle and nerve tissues. Pictures have been found on a
variety of online resources.

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

Structure of Neurons
glial cell that increases the speed of message transmission
transmits messages down neuron towards a muscle or gland
communicates with adjacent cells via neurotransmitters
collects sensory messages to send to cell body
