Question

the most common class of neuron in the central nervous system is
multipolar.
anaxonic.
unipolar.
bipolar.
pseudopolar.

Explanation:

Multipolar neurons have multiple dendrites and one axon. They are the most common type in the central nervous system (CNS) as they are involved in complex neural processing. Anaxonic neurons lack a clearly distinguishable axon. Unipolar neurons have a single process that splits into two (peripheral and central processes), mainly in the peripheral nervous system (PNS) for sensory functions. Bipolar neurons have two processes (one dendrite and one axon) and are found in special sense organs. Pseudopolar neurons are a type of unipolar neuron (originally thought to be bipolar during development).

Answer:

multipolar.
