The Most Abundant Class of Neuron in the Central Nervous

Question

The most abundant class of neuron in the central nervous system is
A) anaxonic.
B) bipolar.
C) multipolar.
D) pseudopolar.
E) unipolar.

Accepted Answer

Multipolar neurons have multiple processes emanating from their cell body, including one axon and two or more dendrites. They are the most common type of neuron found in the central nervous system. Anaxonic neurons lack an axon and are rare, while bipolar neurons have one axon and one dendrite and are found primarily in sensory organs. Pseudopolar neurons have a single process that divides into two branches, and unipolar neurons have a single elongated process that divides into two branches, one acting as an axon and the other functioning as a dendrite. Neither of these are as abundant as multipolar neurons in the central nervous system.
