Students are required to follow all instructions given by the examiners. Talking is NOT allowed under any circumstances. Students may NOT bring any written or printed materials into the examination room except where explicitly allowed by the examiner. Mobile phones are strictly prohibited in the examination room. Students may NOT bring any electronic device into the examination room. Students may raise their hand to ask the examiner a question. The examiner may decide not to answer the question: students are expected to know the requisite terminology and understand the examination questions. Students are NOT allowed to leave the examination room until ready to turn in their work. Once a student has seen the examination paper, the student is assumed to be in good health at the time of the examination. I have read and understood the examination rules. I will not cheat, copy from other students, or use unauthorized materials or devices, and I have not brought such materials or devices into the examination room.

Which of the following events does not happen when the action potential reaches the axon terminal? A. B. C. D. Calcium ions flood into the axon terminal Exocytosis of acetylcholine (ACh) into the synaptic cleft ACh binds to the acetylcholine receptors at the presynaptic membrane ACh binds to the nicotinic acetylcholine receptors at motor end plate 2 HAP-I 2020: Chapters 10 -11 – Quiz 4 8. Which of the following statements about muscle contraction is FALSE? A. At resting state, a myosin head is bound to an ADP and a phosphate that have been produced by splitting an ATP molecule on the myosin head. B.
