Question

Classify neurons based on their structure.

Answer 1

The neurons are classified, based on their structures:

(A) Unipolar neurons

(B) Bipolar neurons

(c) multipolar neurons

(a) Unipolar neurons: Only one nerve process arises from the cyton, which acts as both axon and dendron. It is found in early embryos, but not in the adult.

(b) Bipolar neurons: The cyton gives rise to two nerve processes, of which one acts as an axon, while another acts as a dendron. Bipolar neurons are found in the retina of the eye and the olfactory epithelium of nasal chambers.

(c) Multipolar neurons: The cyton gives rise to many dendrons and an axon. Multipolar neurons found in the cerebral cortex of the brain.
