The movement of positively charged sodium ions across the membrane of a neuron can produce a(n)
A) glial cell.
B) action potential.
C) myelin sheath.
D) interneuron.

Question

Quizplus · Accepted Answer

The movement of positively charged sodium ions across the membrane of a neuron is what triggers the depolarization phase of an action potential, which is ultimately responsible for the transmission of neural impulses. Glial cells, myelin sheaths, and interneurons are all important components of the nervous system, but they are not directly produced by the movement of sodium ions.
