Central Nervous System

consists of brain and spinal cord

CNS

process info, motor response/regulation

parasympathetic nervous system

provides sensory info to CNS

Astrocytes

CNS, Metabolic and structural

microgalia

CNS, remove debris

Oligodendrocytes

CNS, make myelin

ependymal

CNS, cover and line cavities

Satellite Cells

PNS, support

Schwann Cells

PNS, myelin

Somatic (PNS)

motor function of skeletal muscle

autonomic (PNS)

homeostasis, endocrine and cardiac system

sympathetic

fight or flight, increase heart rate decrease digestion

parasympathetic

rest and digest, lower heart rate increase digestion
