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

Detailed explanation-1: -Like the sensory neurons associated with the spinal cord, the sensory neurons of cranial nerve ganglia are unipolar in shape with associated satellite glial cells. There are two types of Autonomic Ganglia: the sympathetic and the parasympathetic based on their functions.

Detailed explanation-2: -Sensory ganglia contain unipolar sensory neurons and are found on the dorsal root of all spinal nerves as well as associated with many of the cranial nerves.

Detailed explanation-3: -Unipolar neurons are typically sensory neurons with receptors located within the skin, joints, muscles, and internal organs. The axons of such neurons are usually long, terminating in the spinal cord.

Detailed explanation-4: -Unipolar neurones possess a single process emerging from the cell body. This divides into dendritic and axonal branches. Neurones of this type constitute the primary afferents of spinal and some cranial nerves, having their cell bodies in the dorsal root ganglia and sensory ganglia of cranial nerves.
