The speed of nerve impulse conduction is increased by the presence of what?

Question

The speed of nerve impulse conduction is increased by the presence of what?

a) axons

b) myelin

c) dendrites

d) cell bodies

Answer 1

Myelin.

Myelination of nerves causes saltatory conduction, which speeds up the conduction of nerve-impulses by skipping between the spaces in the myelin, known as nodes of Ranvier.

Answer 2

AXONS.

Answer 3

MYELIN.

It's the wax-like coating on certain nerve cells. The more there is, the faster the impulse.

Answer 4

Myelin,  because it acts as a conduit.

Answer 5

myelin i guess

The sheath prevents spillage of impulse so i guess that has to be the answer.

Answer 6

b) myelin

google "saltatory conduction" or "nodes of Ranvier"
