WebBiology. Biology questions and answers. How does myelination affect the speed of the action potential? A. by altering the diameter of the axon B. by increasing the concentration gradient of sodium C. by providing additional ATP to the neuron D. by preventing ions from leaking out of the axon.
Why does myelin increase the speed of conduction?
WebThe speed of conduction of an action potential along an axon is influenced by both the diameter of the axon and the axon’s resistance to current leak. Myelin acts as an insulator that prevents current from leaving the axon; this increases the speed of … WebDiameter and conduction speed of primary afferent axons. Group I and A alpha have the largest diameter and fastest speed. Group II and A beta are the next largest and fastest, followed by Group III and A delta. Group IV and C fibers are the slowest and smallest of all axon types. Different sensory information is sent via the different types of ... comic traffic school
Interactions among diameter, myelination, and the Na/K pump affect …
WebAxon Diameter. Axon diameter is also variable and can be used to differentiate different types of neurons. The diameter affects the speed at which the action potential will propagate. The larger the diameter, the faster the signal can travel. Additionally, larger diameter axons tend to have thicker myelin. Figure 1.7. WebLearn more. Q: “Why does an axon diameter increase speed?”. There are two primary reasons: more motive force and less resistance. A larger diameter means there can be … WebMay 6, 2024 · Larger diameter axons have a higher conduction velocity, which means they are able to send signals faster. This is because there is less resistance facing the ion … comic\u0027s 0h
