Glial cells vs myelin sheath

WebApr 8, 2024 · Glial cells are the cell of the nervous system. It is these cells that form the sheath, different types of glial cells form different myelin sheath in the central and peripheral nervous system. The outermost layer of the myelin sheath is known as neurolemma. Neurolemma has the nucleus and cytoplasm of the glial cell. WebFeb 20, 2024 · The second function of the myelin sheath is to speed up the conduction of nerve impulses along the axon. The axons, which are wrapped in cells known as glial cells (also known as oligodendrocytes and Schwann cells), form the myelin sheath. The myelin sheath which surrounds these neurons has a purpose to insulate and protect the axon.

WebFeb 11, 2014 · These stem cells were previously thought to mature only into neurons or a type of glial cell called an astrocyte. The researchers found, however, that chronic stress also made stem cells in the hippocampus mature into another type of glial cell called an oligodendrocyte, which produces the myelin that sheaths nerve cells.

WebSchwann cells (SCs) are the major glial cell type in the peripheral nervous system. They play essential roles in the development, maintenance, function, and regeneration of peripheral nerves. In the mature nervous system, SCs can be categorized into two major classes: myelinating and nonmyelinating cells.
