Neuronal

Question 1

Astrocytes

Answer 1

CNS Neuroglia that form BBB

Question 2

Olgiodendrocytes

Answer 2

CNS Neuroglia that form myelin sheath

Question 3

Microglia

Answer 3

CNS Neuroglia immune cells (phagocytic)

Question 4

Ependymal cells

Answer 4

CNS Neuroglia that produce CSF and make up ependyma lining

Question 5

Satellite cells

Answer 5

PNS Neuroglia that surround cell bodies (like astrocytes)

Question 6

Schwann cells (neurolemmocytes)

Answer 6

PNS Neuroglia that consist of axolemma and neurolemma (like ogliodentrocytes)

Question 7

Somatic vs ANS neurons

Answer 7

Somatic have just one neutron from brain to effector
ANS have two (Pre - Post)

Question 8

Sympathetic cell body location

Answer 8

Grey matter of the thoracic and lumbar sections

Question 9

Parasympathetic cell body location

Answer 9

grey matter of the sacral sections

Question 10

Sympathetic Path to periphery

Answer 10

-Can synapse in Sympathetic chain
-Direct mediation (adrenal medulla)
-Other ganglion

Question 11

White / grey Ramus

Answer 11

the bridges to sympathetic chain (white is from spinal cord) (Grey is effectors)

Question 12

Parasympathetic pathway to periphery

Answer 12

Ganglion are located near the effector organ
