WebApr 12, 2024 · An action potential is defined as a sudden, fast, transitory, and propagating change of the resting membrane potential. Only neurons and muscle cells are capable of generating an action potential; that property is called the excitability. This article will … WebThere are several factors affecting the rate and speed of an action potential: 1. Myelin sheath - This covers some of the nodes and acts as an electrical insulator where the …
WebAnswer: The speed of action potential depends on how far depolarization spreads ahead of action potential. This, in turn, depends on the physical characteristics of axons. The two … WebQuestion: **NEUROSCIENCE QUESTION** 22. Answer the following: i) The propagation velocity of an action potential traveling along an axon depends on: (select all that apply) a. the length constant of the membrane b. the time constant of the membrane c. the number of voltage-gated channels in the membrane d. the axial resistance of the axoplasm ...
