1. What are  three types of neurons?

Ans

  The three  types of neurons are Unipolar, Bipolar and Multipolar

Unipolar:- Have only one process from the cell body.  The  single short process splits into longer processes (a dendrite plus an axon). Unipolar neurons are sensory neurons conducting impulses into the central nervous system.

Bipolar: It has two process, one axon and one dendrite. These neurons are also sensory. eg: Bipolar neurons can be seen in the retina of the eye.

Multipolar:  They have many multiprocesses  that extend from the cell body. They have  lot of dendrites plus an axon.  These  neurons  are either motor or  associating  communications between  neurons with in the  central nervous system.
