Structure of a schwann cell

WebBoth types of Schwann cells are covered by a basal lamina. The outside of the lamina is surrounded by a layer of connective tissue namely the endoneurium, which contains blood vessels, fibroblasts, and macrophages. Whereas, the inner surface of the lamina faces the Schwann cell plasma membrane [4]. Axon Regeneration WebThey play a crucial role in maintaining the structure and function of the nervous system. There are several types of neuroglial cells, including Schwann cells and astrocytes. Schwann cells are found in the PNS and play an essential role in supporting nerve fibers. They wrap around nerve fibers, providing insulation, protection, and nutrition.
