Question
Some neuroglial cells produce the components of the electrical insulator called ______.
Multiple choice question.
- melanocyte
- myelin
- melanin
Solution
Answer
The correct answer is myelin.
Myelin is the electrical insulator that is crucial for the proper functioning of the nervous system. It is produced by specific neuroglial cells: oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS). The myelin sheath wraps around the axons of neurons, allowing for faster transmission of electrical signals through a process called saltatory conduction. This is essential for effective communication between different parts of the nervous system.
In summary, neuroglial cells responsible for producing myelin are key to ensuring rapid signal transmission in the nervous system.
