GENERAL HISTOLOGY

Detailed explanation-1: -What are unipolar neurons? A unipolar neuron only has one nerve process extending from the cell body: an axon that extends into dendrites. Unipolar neurons only occur in invertebrates, such as flies, and are not present in humans. In invertebrates, unipolar neurons play a role in the glands and muscles.

Detailed explanation-2: -Unipolar neurons have only one process and are found mostly in invertebrates. Bipolar neurons are usually oval in shape and contain two processes, a dendrite that receives signals usually from the periphery and an axon that propagates the signal to the central nervous system.

Detailed explanation-3: -The unipolar neurons are characteristically found in invertebrates. However, they can be seen in some invertebrate brains as well. The length of the axonal processes is longer, and that of the dendritic branches varies. Unipolar cells in insects are located at the periphery of the brain and are electrically inactive.
