Question 3

Axon

Answer 3

Sends out info to CNS or out to body

Question 4

Answer 4

Schwann cells

Question 5

Schwann cells

Answer 5

Myelin sheath covered lipid filled cells

Question 6

Where does depolarization/ repolarization take place?

Answer 6

between the schwann cells on the axon

Question 7

Terminal button

Answer 7

at the end of the schwann cells releases neurotransmitters to synapse cleft

Question 8

What allows waves to jump quickly along axon?

Answer 8

Myelin

Question 9

CNS glial cells

Answer 9

oligodentroctes

Question 10

PNS glial cells

Answer 10

schwann cells

Question 11

Grey matter

Answer 11

composed of nerve cell bodies because its not myelinated

Question 12
