Saltatory Conduction

Question

Saltatory conduction:
A) does not involve voltage-activated potassium ion channels.
B) can occur in both myelinated and unmyelinated neurons.
C) is slightly slower than continuous conduction.
D) is more energy efficient than continuous conduction.
E) allows nerve impulses to jump from Schwann cell to Schwann cell.

Accepted Answer

Saltatory conduction is more energy efficient than continuous conduction because it involves the nerve impulse jumping from one node of Ranvier to the next in myelinated neurons, reducing the number of action potentials and thus conserving energy.
