Question

Main parts of a neuron are ............... and .........................

• A. Cell body, axon
• B. Axon hillock, synaptic knob
• C. Cell body, synaptic knob
• D. Myelin sheath, axon

Answer 1

The correct option is A Cell body, axon

The basic parts of a neuron are the dendrites, the cell body and the axon. However, all neurons vary somewhat in size, shape and characteristics depending on the function and role of the neuron. Some neurons have few dendritic branches, while others are highly branched in order to receive a great deal of information. Some neurons have short axons, while others can be quite long. The longest axon in the human body extends from the bottom of the spine to the big toe and averages a length of approximately three feet.

Therefore, the correct answer is option A.
