Which of the following best describes saltatory conduction? Process based on preventing flow of K? across neuronal membranes from outside to inside of cell. Enables action potential to jump from 1 Schwann cell to another. Process which involves unmyelinated neurons. Involves having the action potential travel throughout the whole axon. Process where action potential jumps from one node of Ranvier to another to speed up transmission of the electrical impulse.

Which of the following statements best describes saltatory conduction? a. It inhibits direct neurotransmitter release. b. It transmits the action potential at the nodes of Ranvier and thus speeds up impulses on myelinated axons. c. It increases neurotransmitter release at the presynaptic membrane. d. It decreases neurotransmitter uptake at chemically gated postsynaptic channels. e.It removes neurotransmitters from the synaptic cleft.
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.

Saltatory conduction (a) requires more energy than continuous conduction (b) occurs in unmyelinated neurons (c) occurs when the action potential jumps from one node of Ranvier to the next (d) slows transmission of an impulse (e) depends on the presence of GABA
