Explain what happens when sympathetic neurons stimulate the adrenal medulla. What purpose does this serve?

Video transcript

Hi, everyone. Let's take a look at this practice problem. Together, the release of epinephrine from the adrenal medulla is regulated by the answer. Options are a autonomic nervous system. B sympathetic nervous system, C, both A and B and option D. None of the above recall that the adrenal medulla is the middle portion of the adrenal gland. The adrenal gland sits on top of each kidney on the screen. I am putting up a drawing that shows how epinephrine is released at the top. The hypothalamus in the brain sends nerve signals along the spinal cord and preganglionic neurons. The preganglionic neurons releases acetylcholine in the adrenal medulla, acetylcholine binds receptors and that causes the release of epinephrine from the adrenal medulla. The signals from the hypothalamus that are sent on the pregame. Leon neurons are part of the sympathetic nervous system. Recall that the sympathetic nervous system is responsible for the fight or flight response and releases epinephrine. However, the answer is not just option B, sympathetic nervous system. Remember that the sympathetic nervous system is one of the two divisions of the autonomic nervous system. Therefore, both options A and B are correct. The correct answer is option. C both A and B. All right. Everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
