MUSCLE PHYSIOLOGY

Detailed explanation-1: -Dendrites are tree-like structures that extend away from the cell body to receive messages from other neurons at specialized junctions called synapses. Although some neurons do not have any dendrites, some types of neurons have multiple dendrites.

Detailed explanation-2: -Medicine definition: Axon hillock is an axon nerve fiber that is a long projection of a neuron that carries the outbound neuronal cell signals as opposed to dendrites, which are the short protrusions from the neuronal cell body that brings in the inbound signals to the neuron.

Detailed explanation-3: -These nodes have high concentrations of those channels to restart the action potential along the axon, termed saltatory conduction.[1]

Detailed explanation-4: -An axon (from Greek áxōn, axis), or nerve fiber (or nerve fibre: see spelling differences), is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.
