因 此，星形膠質細胞對維持神經細胞微環境的穩定和調節代謝過程起重 要作用。當中樞神經系統損傷時,星形膠質細胞迅速分裂增殖,以形成 膠質瘢痕形式進行修復。神經纖維（nerve fiber）是以神經細胞的 突起（包括軸突與樹突）為中軸,外包神經膠質細胞（施萬細胞或少突 膠質細胞）。根據神經纖維有無髓鞘包裹,分為有髓和無髓神經纖維兩 種。有髓神經纖維（myelinated nerve fiber）由軸突（或樹突） 、髓鞘、神經膜構成。髓鞘（myelin sheath）及神經膜 （neurolemma）呈鞘狀包裹在軸突的周圍。在軸突的起始部無髓鞘包 裹,稱此部為起始段（initial segment）起始段遠側的軸突部分,髓 鞘呈節段包卷軸突,形似藕節,其間斷部位,軸膜裸露,，可發生膜電位 變化,稱此部位為神經纖維節（node of nerve fiber）,又稱郎飛結 （Ranvier node）。兩個相鄰結之間的一段,稱結間體（internode ），長約0.5～lmm,它是由一個施萬細胞所形成的髓鞘及其周圍的神 經膜構成。施萬細胞核呈長橢圓形，位于髓鞘邊緣的少量胞質內。髓 鞘主要是由類脂質和蛋白質所組成，稱為髓磷脂（myelin）在常規染 色標本上,因髓鞘中的類脂被溶解,僅見殘存的蛋白質呈網狀,稱神經角 演網（neurokeratin network）。在鋨酸浸染標本上,髓鞘呈黑色, 其中還可見數個呈漏斗形的斜裂,稱髓鞘切跡（incisure of myelin ）或施-蘭切跡（Schmidt-Lanterman incisure）。電鏡下,髓鞘為 明暗相間的同心圓板層排列。髓鞘有保護和絕緣作用,可防 止神經沖 動的擴散。有髓神經纖維的神經沖動傳導,是從一個郎飛結跳到相鄰郎 飛結的跳躍式傳導,長的神經纖維,軸突就粗,髓鞘亦厚。結間體也長, 傳導速度快。反之,傳導速度慢。大部分腦、脊神經屬于有髓神經纖維 。 中樞神經系統有髓神經纖維的髓鞘由少突膠質細胞形成。一個少突 膠質細胞的幾個突起,可分別包卷幾條軸突形成髓鞘，其郎飛結較寬, 無髓鞘切跡,其胞體位于神經纖維之間。
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.
