Gaps between the myelin sheath along an axon are called
|
|
Dendrites
|
|
|
Schwann cells
|
|
|
Terminal branches
|
|
|
Nodes of Ranvier
|
Explanation:
Detailed explanation-1: -Nodes of Ranvier are microscopic gaps found within myelinated axons. Their function is to speed up propagation of action potentials along the axon via saltatory conduction. The Nodes of Ranvier are the gaps between the myelin insulation of Schwann cells which insulate the axon of neuron.
Detailed explanation-2: -Synapse is the gap between dendrite ends and axon terminals. This is the gap in which neurotransmitters are released for further transmission of nerve impulses to successive neurons.
