A long process from the cell body
A
Cyton
B
Axon
C
Neurolemma
D
Dendrites
Explanation: 

Detailed explanation-1: -Axon is a long process which develops from a conical prolongation of cyton called axon hillock . Axon is branched distally. The branch ends are expanded to form synaptic knobs. These knobs possess neurotransmitters containing synaptic vesicles.

Detailed explanation-2: -Depending on the type of neuron, axons greatly vary in length-many are just a millimetre or so, but the longest ones, such as those that go from the brain down the spinal cord, can extend for more than a metre.

Detailed explanation-3: -Complete answer: The nervous system consists of special cells called nerve cells or neurons. Cyton is the main cell body which provides many processes called dendrites. A long fiber-like process coming out of the cyton of a nerve cell is named the axon of the nerve fiber.

Detailed explanation-4: -The longest axons of the human body are those that make up the sciatic nerve where the length can exceed one meter. Furthermore, compared to projecting neurons, interneurons usually have smaller soma, fewer organelles, and a reduced amount of cytoplasm (axoplasm).

Detailed explanation-5: -The neuron (nerve cell) has a long extension called an axon. Molecules made in the cell’s main body must travel a long distance to reach the end of the axon.
