Question

Identify the correct match of types of neurons with their location.

i. Unipolar neuron	Embryonic stage
ii. Bipolar neuron	Cornea of eyes
iii. Multipolar neuron	Cerebral cortex

A.(i) and (ii) only
B.(ii) and (iii) only
C.(i) and (iii) only
D.All of these

Answer 1

Hint:
Neurons are known as nerve cells and transmit information in the form of electrical impulses. They are microscopic in nature and constituted of three major parts: cyton, dendrites, and axon.

Complete answer:
Neurons are categorized based on their function, structure, and presence and absence of myelin sheath. Structurally, it is of three types: unipolar neurons, bipolar neurons, and multipolar neurons.
In unipolar neurons, the cell body gives rise to only one nerve possess which acts as both a dendron and an axon. Unipolar neurons are found in the embryonic stage. In multipolar neurons, the cell body gives rise to an axon and many dendrons. The multipolar neuron is found in the cerebral cortex.
In a bipolar neuron, the cell body gives rise to two nerve processes: one acts as an axon while the other acts as a dendron. Bipolar neurons are special neurons that work in the transmission of special senses. As such, they are part of the sensory pathways for smell, sight, taste, hearing, and vestibular functions. They are found in the eye’s retina, not the cornea.
Hence the correct answer is (i) and (iii) only..

Option ‘C’ is correct

Note:
Dendrites are numerous highly branched cytoplasmic extensions arising from the cell body. Axon is a single, unbranched cylindrical projection that arises from the cyton. The axon is covered with a myelin sheath and it is fatty in nature. It carries impulses away from cyton.
