Question

Gaps in the myelin sheath are:

A) not normal
B) spaces between individual neurolemmocytes
C) the parts of the membrane that do not become depolarized during conduction of an action potential
D) seen only along the myelin sheath of dendrites
E) the channels through which neurotransmitters are released

Answer 1

Gaps in the myelin sheath, called nodes of Ranvier, are regularly spaced gaps along the axon that allow the transmission of nerve impulses. These gaps are crucial for the rapid conduction of action potentials.

Step-by-step explanation:

Gaps in the myelin sheath, called nodes of Ranvier, are regularly spaced gaps along the axon. These gaps allow the transmission of nerve impulses and are crucial for the rapid conduction of action potentials. When an action potential reaches a node of Ranvier, it regenerates and jumps to the next node, resulting in a faster propagation of the signal.
