Myelin is a lipid-rich substance that surrounds nerve cell axons to insulate them and increase the rate at which electrical impulses are passed along the axon. The myelinated axon can be likened to an electrical wire with insulating material around it. However, unlike the plastic covering on an electrical wire, myelin does not form a single long sheath over the entire length of the axon. Rather, myelin sheaths the nerve in segments: in general, each axon is encased with multiple long myelinate The removal of the myelin sheath from a nerve fibre, normally as a result of disease + ٢ تعريفا As a result of the autoimmune disease multiple sclerosis (MS), the myelin sheath of neuronal cells in the brain and spinal cord is degraded, resulting in loss of signal transduction capability

ترجمة و معنى كلمة myelin sheath - قاموس المصطلحات

  1. The term demyelination describes a loss of myelin with relative preservation of axons. This results from diseases that damage myelin sheaths or the cells that form them. These diseases should be distinguished from those in which there is a failure to form myelin normally (sometimes described as dysmyelination)
  2. Her own immune system attacked the myelin sheaths around the nerves. لها نظام المناعة الذاتية هاجم الأغماد المايلين حول الأعصاب. Methylmalonyl CoA accumulates when B12 is deficient; this deficiency impairs myelin formation and results in neuropath
  3. myelin sheath n. The insulating envelope of myelin that surrounds the core of a nerve fiber or axon and facilitates the transmission of nerve impulses. In the peripheral nervous system, the sheath is formed from the membranes of Schwann cells, and in the central nervous system it is formed from oligodendrocytes. Also called medullary sheath
  4. MS is a chronic inflammatory disease that destroys the myelin sheaths protecting neurons in the brain and spinal cord, causing problems with vision, balance and mobility
  5. As per the Nodes of Ranvier definition, it is often recognized as myelin-sheath holes, which arise where the axolemma is revealed to the extracellular space along a myelinated axon. Ranvier nodes tend to be uninsulated and have a high concentration of ion channels, permitting them to engage in the ion exchange which is needed to regenerate the action potential
  6. 髓鞘(myelin sheath)是由施旺细胞(Schwann's cell)或其它类型的神经支持细胞形成的。 感覺神經元無論是樹突或軸突都有髓鞘,但其軸突明顯比較短,因為感覺神經元要把外面的感覺傳進來到細胞本體,再經由軸突,傳到下一個細胞,因此樹突很長

  1. Which of the following statements about the myelin sheath is correct? [A] The myelin sheath is a layer of lipid-rich substance secreted by Schwann cells. [B] The myelin sheath helps slow down the speed of electrical conduction. [C] The myelin sheath prevents the nerve cells from being able to undergo cell division. [D] Changes in the structure of the myelin sheath initiate a nervous impulse
  2. The myelin sheath forms as a result of the envelopment of the nerve-cell process by Schwann cells. In the vicinity of the nodes of Ranvier, the myelin sheath is interrupted; the area between any two nodes is formed by a single Schwann cell. The myelin sheath prevents the scattering of nerve impulses and their transfer to other nerve fibers
  3. Biofabrication of nerve fibers with mimetic myelin sheath-like structure and aligned fibrous niche. [en] Nerve tissues contain hierarchically ordered nerve fibers, while each of the nerve fibers has nano-oriented fibrous extracellular matrix and a core-shell structure of tubular myelin sheath with elongated axons encapsulated. Here, we report.

  3. Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system.

  5. These layers form the myelin sheath. Much like the insulation around an electrical wire, the myelin sheath enables nerve signals (electrical impulses) to be conducted along the nerve fiber with speed and accuracy. When the myelin sheath is damaged, nerves do not conduct electrical impulses normally. Sometimes the nerve fibers are also damaged
