The answer is the first one: Schwann cells.

Explanation for each option:

  1. Schwann cells: These are the correct cells that produce myelin in the peripheral nervous system. They wrap around the axons of neurons to form the myelin sheath, which is essential for the rapid transmission of electrical signals.

  2. Oligodendrocyte: This option is incorrect for the peripheral nervous system. Oligodendrocytes produce myelin in the central nervous system, not the peripheral nervous system.

  3. Astrocyte: This option is incorrect. Astrocytes are star-shaped glial cells in the central nervous system that have various functions, including supporting neurons and maintaining the blood-brain barrier, but they do not produce myelin.

  4. Microglia: This option is incorrect. Microglia are the resident immune cells of the central nervous system, involved in protecting the brain from infection and clearing debris, but they do not produce myelin.

In summary, Schwann cells are responsible for producing myelin in the peripheral nervous system.
