A

support neurons, don’t transmit impulses

18
Q

astrocytes

A

neuroglia

blood brain barrier. Largest and most common CNS

19
Q

ependymal cells

A

neuroglia

cuboidal, line ventricles and spinal cord central canal, make CSF

20
Q

Microglia

A

neuroglia

phagocytic cells in CNS

21
Q

Oligodendrocyte

A

neuroglia

form myelin sheaths in CNS

22
Q

Neurolemmocyte

A

-neuroglia
form myelin sheaths in PNS
speed up transmissions

-neuroglia

support the ganglia in PNS

24
Q

resting potential

A

-65mV

25
Q

somatic efferent neurons

vision, hearing, skin, muscles, bones, joints

27
Q

visceral afferent neurons

A

DOG
Deep organs
olfaction (smell)
gustation (taste)

28
