1.The single process of a nerve cell that under normal conditions conducts nervous impulses away from the cell body and its remaining processes (dendrites). It is a relatively even filamentous process varying in thickness from about 0.25 to more than 10 mcm. In contrast to dendrites, which rar...
Definition: A long, slender projection of a nerve cell that conducts electrical impulses away from the cell body Table of Contents What Is Axon? An axon is a thin, long fiber of a nerve cell (or neuron). It transmits electrical impulses from the cell body (or soma) to the target ...

When a nerve is injured so that the axons are disrupted but the connective tissue elements (e.g., endoneurial sheaths, perineurium, and epineurium) remain intact, this injury is called axonotmesis, or a lesion in continuity. This type of injury results in Wallerian degeneration of the axo...
Thus, since suppression of Singar induces axon formation, it is possible to induce and promote axon formation or elongation in nerve cells by suppressing expression or activity of Singar.稲垣 直之森 達也小原 收長瀬 隆弘
阐述神经纤维的分类Classification of nerve fiber。答:常用三种方法分类:⑴按有无髓鞘分为:有髓纤维myelinated nerve fiber和无髓纤维unmyelinated nerve fiber;⑵根据电生理特性分为:生物电传导从快到慢A类:Aα、Aβ、Aγ、Aδ,B类(有髓),C类(无髓);⑶根据直径大小分为:直径从...
Fascinatingly, a neuron’s cell body can measure a tenth of a millimeter across, while itsaxonscan stretch more than 3 feet in length, as in the leg’s sciatic nerve.— Tony Dajer,Discover Magazine, 13 June 2024Nerves, in turn, are made up of bundles ofaxons, the individual filaments...
