Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Autonomic ganglia are made of
A
pseudounipolar neurons
B
unipolar neurons
C
multipolar neurons
D
None of the above
Explanation: 

Detailed explanation-1: -Multipolar neurons are the most common types of neurons in the CNS; they form the autonomic ganglia. They possess a single axon with several symmetrically radiating dendrites. Some neurons have multiple axons or lack axons all together.

Detailed explanation-2: -Motor neurons have the most common type of ‘body plan’ for a nerve cell-they are multipolar, each with one axon and several dendrites.

Detailed explanation-3: -The majority of ganglion cells (74%) termed the “outer ganglion cells, ” are multipolar and are located at the vitread boundary of the inner nuclear layer. The remaining ganglion cells (26%), termed the “inner ganglion cells” are bipolar and are distributed in a sublamina within the inner plexiform layer.

Detailed explanation-4: -Multipolar neurons constitute the majority of neurons in the central nervous system. They include motor neurons and interneurons/relaying neurons are most commonly found in the cortex of the brain and the spinal cord. Peripherally, multipolar neurons are found in autonomic ganglia.
