Question

Saltatory conduction is when the _______ of neurons is covered with a myelin sheath, allowing for faster and more efficient neuronal firing.

a) Dendrites
b) Axons
c) Cell bodies
d) Synapses

Answer 1

Saltatory conduction in neurons involves the action potential jumping from node to node along the myelinated axon, facilitating faster nerve impulse transmission.

Step-by-step explanation:

Saltatory conduction is a process where the action potential within a neuron 'jumps' from one node of Ranvier to the next along the axon of the neuron. This is made possible because the axon is covered in a myelin sheath, which acts as an insulator and speeds up the nerve impulse. The correct answer to the question is b) Axons, as it is the axons of neurons that are covered with the myelin sheath, allowing for faster and more efficient neuronal firing.
