12 multiple choice 1 point
which of the following is true about action potentials?
they involve a decrease in electrical charge inside the neuron.
their strength varies depending on the quantity of neurotransmitter input.
they are primarily involved in sensory processing.
they are brief changes in electrical potential that travel along a neurons axon.

Explanation:

Analyze sympathetic nervous system functions

The sympathetic nervous system prepares the body for action. It triggers physiological changes during high-stress situations. This response is commonly known as the "fight or flight" response. The other options describe the parasympathetic nervous system.

Analyze action potential characteristics

An action potential is a rapid change in membrane potential. It propagates electrical signals down the axon of a neuron. It operates on an "all-or-none" principle, meaning its strength does not vary. During depolarization, the electrical charge inside the neuron increases rather than decreases.

Answer:

Question 11

• (A) Fight or flight response (Correct answer)
• (B) Calming the body
• (C) Rest and digest functions
• (D) Slowing heart rate

Question 12

• (B) Their strength varies depending on the quantity of neurotransmitter input.
• (C) They are primarily involved in sensory processing.
• (D) They are brief changes in electrical potential that travel along a neuron's axon. (Correct answer)
