    REVIEW SHEET EXERCISE 2 Skeletal Muscle Physiology NAME: Jasmine Young LAB TIME/DATE: 1. Define each of the following terms: • motor unit - A motor unit consists of a motor neuron and all of the muscle fibers it innervates. • twitch - Skeletal Muscle twitch is the mechanical response to a single action potential. It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane

    types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct

    Great job once again on answering the question about how muscle action relates to the movement. I think maybe I took it to the extreme‚ I went on about agonist‚ synergist‚ and antagonist muscles. I wasn ’t sure if I should add the levers too. It appears as though you explained every type of muscle movement and gave an example of each. I went into flexion at the elbow and discussed that the agonist is the main muscle mover‚ the antagonist does the opposite‚ and the synergist is the helper. However
