Neural Activity 1
Types of cells
Glia
Radial glia
Guide axon growth over long distances
Oligodendycytes
Form myelin around cells in CNS
Schwann cells
Form myelin around cells in PNS
Microglia
Removes waste material from NS

Conducts impulses to muscles
Sensory neurons
Sensitive to stimulation
Anatomy of neurons

Sends information away from structure
Afferent axon
Brings information into structure
Presynaptic Terminal
Point where axon releases chemicals
