Saltatory conduction is defined as an action potential moving in discrete jumps down a myelinated axon. Many vertebrate axons are surrounded by a myelin sheath, allowing rapid and efficient saltatory ("jumping") propagation of action potentials. The contacts between neurons and glial cells display a very high level of spatial and temporal organization in myelinated fibers. Myelinated Nerve Fibers are nerve fibers that are insulated by a myelin sheath.

Caspr is present at the paranodal junction formed between the axon and myelinating glial cells, whereas Caspr2 is localized and associates with K + channels at the adjacent juxtaparanodal region. Myelinated nerve fiber layer is a developmental anomaly that results from an abnormal extension of myelination anterior to the lamina cribrosa of the sclera.1 In normal fetal development, myelination of the optic nerve begins at the lateral geniculate body, progresses toward the eye, and stops posterior to the lamina cribrosa prior to birth.

The Schwann cell wraps around the axon to envelop it in a myelin sheath that functions as an electrical insulator. Unmyelinated Axons EM of axon from 10 cells revealed that their boutons contain the vesicular GABA transporter (VGAT) and that these often contact axon terminals labeled with vesicular glutamate transporter type 1 (VGLUT1; Figure 1F).

2019-10-17 · In general, a myelinated axon can be described by the following cable equation: (30) where V(x, t) is the trans-membrane potential, I chan (V, t) represents the ionic currents due to the opening of ion channels, and x represents the spatial coordinate longitudinal to the cable. For example, the inward-rectifying K + channel Kir4.1 has been proposed to regulate ion homeostasis at the axon–myelin interface in the CNS (Larson et al., 2018; Schirmer et al., 2018), and so it would be interesting to test whether Kir4.1 and NKCC1 have redundant or distinct roles in maintaining myelinated axon integrity. Axons may be myelinated or unmyelinated, depending on their diameter. Myelin is a membranous sheath that insulates the axon.
