Question
Chapter 45.2, Problem 2CS
Summary Introduction
To sketch: A model representing the neuromuscular junction during exposure to pesticide and predict the effect of pesticide on Na+ channels and muscle function.
Introduction: Muscle contractions are stimulated by the nervous stimuli. The nervous stimuli are in the form of electrical impulse that is transmitted at the neuromuscular junction.

VISUAL SKILLS What will happen in a muscle cell thathas used up its supply of oxygen and ATP? (ReviewFigures 9.18 and 9.20.)
VII. Real life problem. You are a trainer and are called on to the field where a player is down with a severe cramp of his right hamstring (biceps femoris) muscle. You know that cramps are caused by over-active motor nerve activity to the muscle. Your associates want to stretch the cramping hamstring, but you say, “No! I want the player to concentrate on contracting his right quadriceps muscles before we stretch.”
2. Why would contracting the opposing muscle rapidly improve the situation?

Some factors that have been proposed to explain the fall in force duringfatigue include: changes in the 'sense of effort', loss of 'central drive', failure of neuromuscular propagation, reduction in calcium release in excitation- contraction coupling, metabolic changes in the muscle, and reduction in muscle blood flow owing to compression of blood vessels. 1.

Insert numbers in the paces provided to order the events in the proper sequence. _____ A. An electrical impulse travels over the sarcolemma and inward along the T-tubules, causing sacs in the sarcoplasmic reticulum to release calcium. ____ B. The release of ACh stops and acetylcholinesterase breaks down any remaining ACh. _____ C. Troponin and tropomyosin prevent the myosin heads from grasping the thin filament, and the muscle fiber relaxes. _____ D. An electrical impulse causes small vesicles at the end of a motor neuron to release the neurotransmitter acetylcholine (ACh). _____ E.
