Question

voltage-gated sodium channels at a neuron's initial segment are triggered to open when the membrane becomes more positive. (True or False)

Answer 1

Answer: True

Explanation:

It is true because Voltage-gated sodium channels are ion channels found in the membranes of neurons, specifically at the initial segment or axon hillock. These channels are responsible for generating and propagating action potentials, which are electrical signals that allow neurons to communicate with each other.
