Therefore, astrocytes play an important role in maintaining the stability of the neuronal microenvironment and regulating metabolic processes. When the central nervous system is damaged, astrocytes rapidly divide and proliferate, and repair in the form of glial scars. The nerve fiber is the central axis of the projections of nerve cells (including axons and dendrites), and is outsourced to glial cells (Schwann cells or oligodendrocytes). According to whether the nerve fiber is surrounded by myelin sheath, it is divided into two kinds of myelinated and unmyelinated nerve fibers. Myelinated nerve fibers consist of axons (or dendrites), myelin sheaths, and nerve membranes. The myelin sheath and the neurolemma are sheathed around the axons. At the beginning of the axon, there is no myelin sheath, which is called the axon part distal to the initial segment of the initial segment. The myelin is a segmental reel-shaped process, resembling a ganglion, and its intermittent site. Axial membrane exposure, can occur changes in membrane potential, called this site for the nerve fiber node (node ??of nerve fiber), also known as Langfei junction (Ranvier node). A section between two adjacent junctions, called the internode, is about 0.5 to 1 mm long. It consists of a myelin sheath formed by a Schwann cell and the surrounding nerve membrane. Schwann cell nuclei are oblong in shape and located within the cytoplasm of the myelin sheath. Myelin sheath is mainly composed of lipids and proteins, called myelin (myelin) in the conventional staining specimens, because the lipid in the myelin was dissolved, only the remaining protein was mesh, called the nerve angle network ( Neurokeratin network). In the tannic acid-exposed specimens, the myelin sheath was black, and several funnel-shaped oblique fissures were also seen, called incisure of myelin or Schmidt-Lanterman incisure. Under electron microscope, the myelin sheaths are arranged in a light and dark concentric circular plate. Myelin sheath protects and insulates and prevents the spread of nerve impulses. The nerve impulse conduction of myelinated nerve fibers is a jump-type conduction that jumps from a Langfei knot to the neighboring Langfei knot. Long nerve fibers have thick axons and thick myelin sheaths. The junction body is also long and the conduction speed is fast. On the contrary, the conduction speed is slow. Most brain and spinal nerves are myelinated nerve fibers. The myelin sheath of the myelinated nerve fibers of the central nervous system is formed by oligodendrocytes. A few protrusions of an oligodendrocyte can wrap several axons to form a myelin sheath. The Lange junction is wider and has no myelin sheath. The cell body is located between nerve fibers.
