WebRetrograde transmission can inhibit presynaptic neurons from releasing additional neurotransmitters and help control the level of activity and communication among neurons. ... Velocity depends on axonal diameter and degree of myelination and ranges from 1 to 4 m/sec in small unmyelinated fibers to 75 m/sec in large myelinated ones. Propagation ... WebSep 27, 2024 · The presence of the synaptic cleft between the synaptic end bulb of the neuron and the motor end plate of the muscle fiber, means that the electrical signal or action potential, arriving from the central nervous system, needs to somehow transverse (cross) this space.The neuromuscular junction accomplishes this by turning the electrical signal …

WebSize. Action potentials travel down neuronal axons in an ion cascade. Positive ions (mostly sodium ions) flow into the cell body, which triggers transmembrane channels at the start of the axon to open and to let in more positive ions. These new positive ions trigger the channels next to them, which let in even more positive ions. WebHowever, the basic properties of synaptic transmission at the skeletal neuromuscular junction are very similar to the process of synaptic transmission in the central nervous system. Figure 4.1 (see enlarged …
