Answer 14

CNS

Question 15

second neuron cell body resides in

Answer 15

peripheral ganglia

Question 16

required for peristalsis

Answer 16

smooth muscle is perpendicular to nerve cells

Question 17

exist as a plexus

enteric ganglia

Question 18

neurokeratin is specific to

Answer 18

myelination

Question 19

1:1 shwan cell to axon explain

Answer 19

for unmylinated axons one shwan cell will cover many of them but for mylinated axon there is a 1:1 relationship

end to end junction between shwan cells

Answer 25

nodes of ranvier

Question 26

why doe we need nodes of ranvier?

for Reflex!!!!

unmylenated

Question 28

perineural sheath

Answer 28

blood brain barrier

Question 29

Cytoplasmic channels that allow nutrient exchange between the axon and the Schwann cell
