Anatomy and Physiology Final Exam
Review: All multiple choice and open
ended questions
1. Cross bridges form between... - CORRECT ANSWERS-The actin filaments and the myosin
heads
2. True or False: Acetylcholine is down into acetic acid and cholinesterase by choline. -
CORRECT ANSWERS-True
3. Neuron receptor proteins that signal for muscular contraction upon a chemical stimulus
are called ___________. - CORRECT ANSWERS-Acetylcholine receptors
4. What structures do the calcium ions bind to when muscle contraction is initiated? -
CORRECT ANSWERS-Troponin molecule
5. The neurotransmitter in the neuromuscular junction... - CORRECT ANSWERS-Caused
