Textbook Question
Chapter 40.1, Problem 3CC
WHAT IF? Ø Suppose you are standing at the edge of a cliff and suddenly slip, barely managing to keep your balance and avoid falling. As your heart races, you feel a burst of energy, due in part to a surge of blood into dilated (widened) vessels in your muscles and an upward spike in the level of glucose in your blood. Why might you expect that this "fight-or-flight" response requires both the nervous and endocrine systems?

- Watch this video (http://openstaxcollege.org/l/fightflight) to learn more about adrenaline and the fightor-flight response. When someone is said to have a rush of adrenaline, the image of bungee jumpers or skydivers usually comes to mind. But adrenaline, also known as epinephrine, is an important chemical in coordinating the bodys fight-or-flight response. In this video, you look inside the physiology of the fight-or-flight response, as envisioned for a firefighter. His bodys reaction is the result of the sympathetic division of the autonomic nervous system causing system-wide changes as it prepares for extreme responses. What two changes does adrenaline bring about to help the skeletal muscle response?arrow_forwardWHAT IF?

- Long-distance runners (26.2 miles) describe Runner’s High as a feeling of euphoria. It is often described as a feeling of being invincible and individuals claim a lost sense of time while running. Runner’s high is believed to be caused by very small molecules called endocannabinoids released by the brain that affect the way a person feels, moves, and reacts. Based on the information above what you know of interacting systems, which of the following two are correct? A. If the release of endocannabinoid molecules is increased, the runner will not experience the feeling of euphoria and will stop running. B. The muscular system is not affected by the release of endocannabinoids, which are released by the nervous system. C. If the function of the nervous system is compromised and endocannabinoids are not released, the function of the muscular system is affected and prolonged endurance will be jeopardized. D. The release of endocannabinoids at the cellular level plays an indirect…arrow_forwardA scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study?arrow_forwardYou are designing neurotransmitters and hormones. 1. Which should have a higher affinity for their receptors? 2.
