Question

Column I		Column II
a	Unipolar neuron	1	One axon and one dendrite
b	Bipolar neuron	2	Cell body with one axon
c	Multipolar neuron	3	One axon and two or more dendrites

• A. $a—1,b—2,c—3$
• B. $a—3,b—1,c—2$
• C. $a—2,b—3,c—1$
• D. $a—2,b—1,c—3$

Answer 1

Answer: (D)

Based on the number of axon and dendrites, the neurons are divided into three types :
1. Unipolar: Cell body with one axon only; found usually in the embryonic stage.
2. Bipolar: With one axon and one dendrite, found in the retina of eye.
3. Multipolar: With one axon and two or more dendrites; found in the cerebral cortex.
