By studying axonal pathology in human multiple sclerosis and its models, we observed that myelin ensheathment itself can be detrimental for axonal survival. We hypothesize that oligodendroglial support is disrupted under inflammatory conditions, with the most severe consequences for the axons that ...
In addition, myelin wrapping is disturbed with the leading edge moving away from the axon and in between previously formed layers. These data show how two adhesive systems function together to guide axonal ensheathment and myelin wrapping, and provide a mechanistic understanding of how the spatial...
Relationship between myelin sheath diameter and internodal length in axons of the anterior medullary velum of the adult rat Relations between diameters and internodal lengths were measured in whole mounts of stained intact anterior medullary velum () from perfused adult . The is... M Ibrahim,AM But...
Glial cells that elaborate myelin in the CNS. Unlike Schwann cells in the PNS that myelinate single axons, oligodendrocytes typically ensheath several processes at once. Astrocytes The most abundant glial cell in the CNS, with a star-shaped cell body and broad end-feet on their processes. Astr...
Answer to: Schwann cells form the myelin sheath around multiple axons at once and the neurilemma which aids in axon regeneration after injury. a...
Relation between myelin sheath thickness and axon size in spinal cord white matter of some vertebrate species. The relation between number of myelin lamellae and axon size in the CNS was examined by electron microscopy of spinal cord white matter fibres in different... C Hildebrand,R Hahn - 《...
很多轴索被环绕所作一种被分割的,白色,脂肪过多的物质打电话给 myelin 或 myelin sheath.Myelinated 纤维在 CNS 中编造白质,当细胞身体和 unmyelinated 纤维为被 unmyelinated 的灰色 matter.The 做 myelin 段之间的地区称为 Ranvier 的节点。 2013-05-23 12:28:18 回答:匿名...
This Review presents a comparison of the glial response to injury between the CNS and PNS and highlights features of the PNS glial response that, with continued study, might reveal long-sought-after keys to achieving CNS repair. 展开 关键词: Central Nervous System Neuroglia Myelin Sheath Axons ...
Nuclei are concentrations of nerve cell bodies in CNS. True False Which of the following statements are true of nerve tissue? a. The electrical nerve impulse is carried by the neuron's cell membrane b. The myelin sheath assists impulse transmission across synapses...
Only Group 3 axons survived long term in significant numbers, and all became myelinated by oligodendrocytes, ultimately establishing thin sheaths with relatively normal nodal gaps and intersegmental myelin sheath lengths. Schwann cells at the CNS/PNS junction of the IVth nerve rootlet did not ...
