Which cells in the body are commonly referred to as the "nerve glue" due to their supportive role in the nervous system?

• A. Glial cells
• B. Neurons
• C. Schwann cells
• D. Oligodendrocytes

Answer: (A)

Verified step by step guidance

1. Understand the context of the question: The term 'nerve glue' refers to cells in the nervous system that provide structural and functional support to neurons, rather than directly transmitting nerve impulses.
2. Review the roles of each cell type listed in the options: Glial cells, Neurons, Schwann cells, and Oligodendrocytes.
3. Clarify the function of glial cells: Glial cells are non-neuronal cells in the nervous system that provide support, protection, and insulation for neurons. They are often referred to as 'nerve glue' because they help maintain the structure and function of the nervous system.
4. Differentiate glial cells from neurons: Neurons are the primary signaling cells in the nervous system responsible for transmitting electrical impulses, not for structural support.
5. Examine Schwann cells and Oligodendrocytes: Schwann cells and Oligodendrocytes are specific types of glial cells that produce myelin, which insulates axons to enhance signal transmission. While they are glial cells, the term 'nerve glue' broadly refers to all glial cells, not just these subtypes.
