(Neurology)

Question 1

The main purpose of myelin

Answer 1

to increase the speed at which electrical impulses propagate along the myelinated fiber.

Question 2

In unmyelinated fibers, electrical impulses (action potentials) travel as ___

Answer 2

continuous waves

Question 3

Saltatory conduction (from the Latin saltare, to hop or leap) is the ___ of action potentials along ___ axons from one node of Ranvier to the next node, increasing the conduction ___ of ___ ___

Answer 3

Saltatory conduction (from the Latin saltare, to hop or leap) is the PROPAGATION of action potentials along MYELINATED axons from one node of Ranvier to the next node, increasing the conduction VELOCITY of ACTION POTENTIALS.
