If there were lesions on a bundle of myelinated fibers, what would occur?
A)Nerve conduction would be enhanced with an increase in motor coordination.
B)There would be no side effects of these types of lesions.
C)Nerve conduction would be impaired, and weakness, loss of coordination, and visual impairment would occur.
D)Nerve conduction would be impaired, and neuromas would develop.

Question

Quizplus · Accepted Answer

Lesions on a bundle of myelinated fibers would impair nerve conduction and can lead to weakness, loss of coordination, and visual impairment. This is because myelin provides insulation for nerve fibers and allows for fast conduction of nerve impulses. When the myelin is damaged, the impulse transmission is slowed down, leading to various neurological symptoms. Options A and B are incorrect as there would be no enhancement or no side effect of such lesions. Option D is incorrect as neuromas are growths that develop on nerve cells and not necessarily a result of myelin damage.
