What is the embryonic origin of skeletal muscle cells? the enzyme that breaks down acetylcholine in the synaptic cleft, during repolarization the cell cannot be stimulated again until repolarization is complete, the force exerted by a contracting muscle on an object, the opposing force exerted on the muscle by the weight of the object to be moved, A motor neuron and all of the muscle fibers it innervates, a chart of the timing and strength of a muscle's contraction, the response of a muscle to a single stimulation, the first few milliseconds following stimulation when excitation-contraction coupling is occuring; during this period, muscle tension is beggining to increase, cross bridges are active, from the onset to the peak of tension development, and the myogram tracing rises to a peak, final phase, lasting 10-100ms, is initiated by reentry of Ca2+ into the SR; muscle tension decreases to zero and tracing returns to baseline, depends on tension produced by each fiber and number of fibers contracting, if two identical stimuli (electrical shocks or nerve impulses) are delivered to muscle in rapid succession, the second twitch will be stronger then the first; this occurs because second contraction occurs before the muscle has completely relaxed; primary function is to produce smooth continuous muscle cells, some relaxation occurs between contractions, but nerve stimuli arrive at an even faster rate than during summing of contractions, unless the muscle contraction is smooth and sustained, No evidence of relaxation before the following contractions Let knowledge be the cure. muscle tissue: an overview labster quizlet - gengno.com What's that? aerobic and anaerobic metabolism is used, and they are in major muscles of the leg. . Whole skeletal muscle is made up of many fibers(cells) held together with _______________________________ tissue.
