Question

protect axon and increase speed of impulses

schwan cell
sinaptic knob
dendrite
cyton/cell body​

Answer 1

Answer:

Found Something similar to the question....

Explanation:

Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length. Myelin damage causes several neurological diseases, such as multiple sclerosis.

Answer 2

It’s Schwann cell cause when Schwann cell is present there will be myelin sheathing around axon which results in saltatory conduction i.e, speeding of impulse by jumping from one Schwann cell to another.

Good luck
