What is the name of the protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells but also adds to brain weight?

Question

Quizplus · Accepted Answer

The protective insulation that surrounds parts of neurons and speeds the transmission of electrical impulses along brain cells is called myelin. Myelin also adds to the weight of the brain, as it forms a significant portion of the white matter in the brain. Therefore, the correct option is C. The reticular formation (A) is a network of neurons in the brainstem involved in regulating sleep and arousal. The corpus callosum (B) is a band of fibers connecting the two hemispheres of the brain, allowing for communication between them. The cerebellum (D) is a structure located at the base of the brain, involved in motor coordination and balance.
