Special types of glial cells generate a protective fatty substance called

• A. dendrites.
• B. myelin.
• C. axons.
• D. cholesterol.

Answer: (B)

Verified step by step guidance

1. Identify the key terms in the problem: 'glial cells', 'protective fatty substance', and the options provided.
2. Understand the role of glial cells in the nervous system. Glial cells support and protect neurons, and some types are involved in the formation of myelin.
3. Recognize that myelin is a fatty substance that forms a sheath around the axons of neurons, providing insulation and increasing the speed of electrical impulses.
4. Differentiate between the terms: 'dendrites', 'axons', 'myelin', and 'cholesterol'. Dendrites receive signals, axons transmit signals, myelin insulates axons, and cholesterol is a different type of lipid found in cell membranes.
5. Conclude that the special type of glial cells responsible for generating the protective fatty substance is related to myelin, which insulates axons.
