Nerves

?

Cells of the Nervous System = Neurons and Glia

1) NEURONS = Receive and transmit information to other cells 

Axons can be AFFERENT - brings info into a structure or EFFERENT - carries info away from the structure 

Sensory neuron - Relay Neuron - Motor Neurone 

2) GLIA = Many functions, support neurons in their functions

Smaller, but more numerous, don't transmit messages across long distances
