Question

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once.

The action potential is a wave of _________ that spreads rapidly along the neuronal plasma membrane. This wave is triggered by a local change in the membrane potential to a value that is _________ negative than the resting membrane potential. The action potential is propagated by the opening of _________-gated channels. During an action potential, the membrane potential changes from ___________ to ________. The action potential travels along the neuron's _________ to the nerve terminals. Neurons chiefly receive signals at their highly branched ________.
a) Depolarization
b) More
c) Voltage
d) Less
e) Axon
f) Dendrites

Answer 1

The action potential is a depolarization event that converts the membrane potential from negative to positive and propagates along the axon due to voltage-gated channels, finally transmitting signals through the dendrites.

Step-by-step explanation:

The action potential is a wave of depolarization that spreads rapidly along the neuronal plasma membrane. This wave is triggered by a local change in the membrane potential to a value that is less negative than the resting membrane potential. The action potential is propagated by the opening of voltage-gated channels. During an action potential, the membrane potential changes from negative to positive. The action potential travels along the neuron's axon to the nerve terminals. Neurons chiefly receive signals at their highly branched dendrites.
