Lab #9: muscle physiology p1 lab #9: muscle physiology background overview of skeletal muscle contraction skeletal muscle fibers are very large, elongated cells (fig 91) roughly 80% of the content of each muscle fiber consists of long bundles of protein called myofibrils the myofibrils, in turn, consist of two types of myofilament (fig 92. Viii completing your report your lab report should have: 1 all data sheets completed 2 a graph of graded response and maximal stimulus 3 a graph of load versus work done 4 a printout of a muscle twitch with all phases of a twitch contraction labeled 5 a printout showing summation 6 a printout showing tetanus cleanup and disposal 1. In this experiment, the isolated skeletal muscle was repetitively stimulated such that individual twitches overlapped with each other and resulted in a stronger muscle contraction than a standalone twitch.

The procedure and methods used for the experiment can be found in “npb 101l physiology lab manuel” (2009) exercise 2, properties of skeletal muscle on pg 9-17 for the experiment a. Skeletal muscles respond to a stimulus in an all- or- none fashion, and their response is known as a twitch one motor neuron supplies a number of muscle fibers to compose a motor unit, which can very greatly in size.

Lab 4 biomechanics of frog skeletal muscle i purpose this exercise is designed to demonstrate some mechanical and physiological properties of skeletal muscle using the gastrocnemius muscle of a frog.
Electromyography can be used to diagnose the cause of muscle weakness electromyography can help to differentiate primary muscle conditions, such as muscular dystrophy, from muscle weakness caused by neurological disorders, such as multiple sclerosis emg is also used in studies of kinesiology and exercise physiology.
