Webual axon may be ensheathed by myelin from several oligo-dendrocytes, periodic gaps are present in the sheath. These are termed the nodes of Ranvier and are the sites of propagation of the action potential. Myelin can thus be regarded as a discontinuous insulation that enables the salta-tory conduction of the action potential.

The main purpose of myelin is to increase the speed at which electrical impulses (known as action potentials) propagate along the myelinated fiber. In unmyelinated fibers, action potentials travel as continuous waves, but, in myelinated fibers, they "hop" or propagate by saltatory conduction. The latter is markedly faster than the former, at least for axons over a certain diameter. Myelin decreases capacitance and increases electrical resistance across the axonal membrane (the axole… エアウォーターテクノサプライ求人Webaxon hillock and nodes of Ranvier. sarin nerve gas paralyzes muscle by interfering with neuronal transmission by which of the following. ... the _____ is the discontinuous insulation of an axon. myelin sheath ____ receptors, which act in an indirect manner, act more slowly than inotropic receptors. metabotropic. palio ferrara 2022WebJul 29, 2024 · An axon is a thin fiber that extends from a neuron, or nerve cell, and is responsible for transmitting electrical signals to help with sensory perception and movement.
