Verified step by step guidance

Understand the role of Schwann cells in the nervous system. Schwann cells are a type of glial cell found in the peripheral nervous system (PNS).

Recognize that Schwann cells are not involved in transmitting electrical impulses between neurons. This function is primarily performed by neurons themselves.

Identify that Schwann cells are not found in the central nervous system (CNS). Instead, oligodendrocytes perform a similar function in the CNS.

Learn that Schwann cells are responsible for forming the myelin sheath around axons in the peripheral nervous system. This myelin sheath is crucial for the rapid transmission of electrical signals along the nerve cells.

Clarify that Schwann cells do not form the blood-brain barrier. The blood-brain barrier is primarily formed by endothelial cells in the CNS, with the help of astrocytes.
