Neural Control And Coordination Question 3
Question: Several nervous system diseases result from a loss of support cells or of substances produced by support cells (such as myelin). The primary function of these support cells is to:
Options:
A) Act as supporting structures within nervous tissue.
B) Produce insulating material around axons.
C) Assist in the conduction of impulses along neurons.
D) All of the above
Show Answer
Answer:
Correct Answer: B
Solution:
Support cells in the nervous system, such as oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, are responsible for producing myelin. Myelin acts as an insulating material around axons, which enhances the speed and efficiency of nerve impulse conduction along neurons. While these cells do provide some structural support within nervous tissue, their primary role and significance lie in insulating axons rather than directly supporting nervous tissue structurally or assisting in the conduction of impulses. Therefore, option B is the most accurate statement regarding the primary function of these support cells.
