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. occurs only in myelinated nerve fibers. b. is slower than other types of nerve conduction. c. occurs only in the central nervous system. d. is the way an impulse gets from one neuron to another.
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 action of GABA
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. It removes neurotransmitters from the synaptic cleft.
