Axon

Detailed explanation-1: -The myelin sheath is a layer of fatty tissue surrounding the axon of a neuron that both acts as an insulator and allows faster transmission of the electrical signal. Axons branch out toward their ends, and at the tip of each branch is a terminal button.
Detailed explanation-2: -Motor neurons that are involved in movement such as walking need Myelin Sheath insulation for quick signal conduction. Sensory neuron functions, hearing, seeing, or sensation of pain, are also dependent upon the myelin sheath insulation.
Detailed explanation-3: -Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a neuron varies. They are called afferent processes because they transmit impulses to the neuron cell body.
