Figure 35.26 Which of the following statements is false? The parasympathetic pathway is responsible for relaxing the body, while the sympathetic pathway is responsible for preparing for an emergency. Most preganglionic neurons in the sympathetic pathway originate in the spinal cord. Slowing of the heartbeat is a parasympathetic response. Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine.

Your roommate has a severe peanut allergy. When exposed to peanuts, their lungs close up. How does an epi-pen prevent this from happening? A. Epinephrine will antagonize the muscarinic receptors in the lungs, preventing bronchoconstriction B. Epinephrine will antagonize the adrenergic receptors in the lungs, stimulating bronchodilaton. C. Epinephrine will agonize the adrenergic receptors in the lungs, causing bronchodilation. D. Epinephrine will agonize the muscarinic receptors in the lungs preventing bronchoconstriction.

Which statement about nicotinic acetylcholine receptors (nAChRs) is true? a. Each nAChR is composed of seven different protein subunits. b. They are ionotropic receptors and conduct Na+ and Ca2+ ions across the cell membrane causing depolarization and a fast excitatory response. c. They are ionotropic receptors and conduct K+ ions across the cell membrane, causing depolarization and a fast excitatory response. d. They are found in all areas of the nervous system except the brain.

The venom of some cobras contains a mixture of substances that have a variety of physiological effects. One substance in the venom works by preventing acetylcholine from binding to muscle receptors. Which of the following describes the effect of the venom on the prey of the cobra? Question 5 options: Muscle contractions are prevented, causing paralysis. Muscle contractions occur, but refractory periods would be longer. Action potentials are continuously generated, causing tetanus. Weak muscle contractions occur but are limited by ATP production by glycolysis.
