NEETZoologyNeural Control and Coordination
Which of the following options correctly identifies the sequence of structural descriptions for the primary neural tissues found in the embryonic stage, the cerebral cortex, and the somatic neural system, respectively?
Options
- ACell body with one axon only ; One axon and two or more dendrites ; Enclosed by a Schwann cell that does not f
- BOne axon and two or more dendrites ; Cell body with one axon only ; Enclosed by a Schwann cell that does not f
- CCell body with one axon only ; One axon and one dendrite ; Enclosed by a Schwann cell that does not form a mye
- DCell body with one axon only ; One axon and two or more dendrites ; Enveloped with Schwann cells forming a mye
Correct answer
A. Cell body with one axon only ; One axon and two or more dendrites ; Enclosed by a Schwann cell that does not f
Step-by-step solution
The question requires mapping anatomical locations directly to their structural definitions based on NCERT: 1. Embryonic stage: Neurons here are typically unipolar, defined structurally as having a cell body with one axon only. 2. Cerebral cortex: Neurons here are multipolar, defined structurally as having one axon and two or more dendrites. 3. Somatic neural system: Nerve fibres here are unmyelinated, defined structurally as being enclosed by a Schwann cell that does not form a myelin sheath around the axon. Optio
