These neurons secrete acetylcholine, which ultimately results in a decreased heart rate. This is an example of A. Endocrine control B. Exocrine control C. Hormonal control D. Neural control E. None of the choices are correct Bloom's Level: 3. Apply Section 1.07 Topic: Nervous System 32. Heart rate is affected by the release of epinephrine by the adrenal medulla into the bloodstream. This is an example of A. Endocrine control B. Exocrine control C. Paracrine control D. Direct neural control E. None of the choices are correct Bloom's Level: 3. Apply Section 1.07 Topic: General 33. Which of the following is/are functions of the human nervous system? A. Receiving, storing and processing information on the internal and external environments B. Bringing about changes in physiology and/or behavior to ensure optimal functions of homeostatic mechanisms C. Secretion of hormones D. Both receiving, storing and processing information on the internal and external environments and bringing about changes in physiology and/or behavior to ensure optimal functions of homeostatic mechanisms are correct E. All of the choices are correct Bloom's Level: 1. Remember Section 1.02 Topic: Nervous System Chapter 01 - Homeostasis: A Framework for Human Physiology 1-12 34. Which of the following statements applies to autocrine regulation? A. Chemical regulators are released directly into blood vessels B. Chemical regulators released by cells affect the functional status of different kinds of cells in the vicinity of the secretory cell C. Chemical regulators affect the same cell that produced it D. Chemical regulators reach their site of action through a duct E. Chemical regulators are continuously released in constant amounts by the cell Bloom's Level: 1. Remember Section 1.07 Topic: General 35. The tall slender body shape that helps to dissipate heat in people native to equatorial regions is an example of A. An adaptation B. Acclimatization C. Set point resetting D. Homeostasis E. Phase-shift Bloom's Level: 3. Apply Section 1.08 Topic: Evolution 36. After spending several days at a high altitude, where oxygen pressure is low, a person will begin to produce more red blood cells, which enhances the ability of his/her blood to carry oxygen to the tissues. Which of the following control mechanisms best describes this response? A. Developmental acclimatization B. Positive feedback C. Physiological acclimatization D. Feedforward regulation E. None of the choices are correct
