Question:
The Lesion at myelin on Nerve cell due to impair
The Lesion at myelin on Nerve cell due to impair
Show Hint
Myelin = Speed. No myelin = No signal (Action Potential) speed or efficiency.
Updated On: May 25, 2026
- Salvation
- Neurotransmitter synthesis
- Release from synaptic vesicles
- Generation of action potential at Hillock
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Myelin is the insulating layer around axons that facilitates rapid signal conduction.
Step 2: Meaning
A lesion (damage) to the myelin sheath impairs the propagation and generation of electrical impulses.
Step 3: Analysis
The axon hillock is the site where summation of potentials occurs to initiate an action potential. Myelin damage disrupts the saltatory conduction and the overall electrical integrity of the neuron.
Step 4: Conclusion
Impaired myelination directly impacts the efficient generation and conduction of action potentials. Final Answer: (D)
