Question

question 10 1 pts a term commonly used as a synonym for action potential is repolarization. stimulus. nerve impulse. depolarization. question 11 1 pts an ion channel that opens in response to a sensory stimulus is a(n) ionic channel. stimulus - gated channel. local potential. sodium - potassium channel. question 12 1 pts a neurologist is using a voltmeter to measure potential. the membrane potential of a neuron was recorded at +30 mv. this is what type of membrane potential? polarized resting conduction action

Explanation:

• Question 10: An action potential is the electrical signal transmitted along a neuron, and nerve impulse is a common synonym. Repolarization is the return of the membrane potential to its resting state after depolarization. A stimulus is what initiates an action potential. Depolarization is the change in membrane potential that makes it less negative.
• Question 11: Ion channels that open in response to a sensory stimulus are called stimulus - gated channels. An ionic channel is a general term for a channel that allows ions to pass. Local potential is a small change in membrane potential. Sodium - potassium channels are involved in maintaining the resting membrane potential by actively transporting sodium and potassium ions.
• Question 12: A membrane potential of +30 mV in a neuron is an action potential. A polarized state is the normal resting state with a negative membrane potential. The resting membrane potential of a neuron is typically around -70 mV. Conduction refers to the propagation of an electrical signal, not a specific type of membrane potential value.

Answer:

• Question 10: C. nerve impulse
• Question 11: B. stimulus - gated channel
• Question 12: D. Action
