Question

practice it
what is saltatory conduction?
a type of action potential propagation that occurs in the dendrites of neurons
a type of action potential propagation that occurs in myelinated axons where the signal jumps from node to node
a type of action potential propagation that occurs in the synapses between neurons
a type of action potential propagation that occurs in unmyelinated axons where the signal jumps from node to node
a type of action potential propagation that occurs in myelinated axons where the signal travels smoothly along the axon

Explanation:

Saltatory conduction is the rapid transmission of a nerve impulse along a myelinated axon. The myelin sheath insulates the axon and the action potential 'jumps' from one node of Ranvier (gaps in the myelin sheath) to the next.

Answer:

B. A type of action potential propagation that occurs in myelinated axons where the signal jumps from node to node
