In myelinated the impulse jumps from node to node what is this transmission called?
Correct answer: C. Saltatory impulse
- A. Myelinated impulse
- B. Jumping impulse
- C. Saltatory impulse
- D. All of these
Explanation
Saltatory conduction describes the way an electrical impulse skips from node to node down the full length of an axon, speeding the arrival of the impulse at the nerve terminal in comparison with the slower continuous progression of depolarization spreading down an unmyelinated axon.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
