    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

    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

    Results A left gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force

    order for a muscle to contract requires a nerve impulse to arrive at the neurotransmitter junction. This then causes a release of acetylcholine (ACh) from the presynaptic terminal. By binding with its receptors on the membrane of the muscle fiber‚ which opens sodium channels generating an action potential that spreads through the length of the fiber‚ stimulating release of calcium from the sarcoplasmic reticulum. Calcium is what activates the contractile mechanism‚ causing the muscle fiber to shorten

    between the application of the stimulus and the last point where the active force is zero (just prior to contraction). How long is the latent period? _2.78_ msec What occurs in the muscle during this apparent lack of activity? The muscle is reacting internally and getting the signals to contract.

    Lab 6 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. II. Performance Objectives At the end of this exercise the student should be able to: 1. Define minimal (threshold)‚ subminimal‚ maximal‚ and supramaximal stimulus. 2. Explain what is meant by a “graded” response. 3. Draw a diagram of the setup used in this lab exercise. 4. Calculate the

    What is the voltage beyond which there were no further increases in active force? Maximal voltage: 8.5 V 4. Why is there a maximal voltage? What has happened to the muscle at this voltage? 5. An individual muscle fiber follows the all-or-none principle—it will either contract 100% or not at all. Does the muscle we are working with exhibit the all-or-none principle? Why or why not? Yes be Multiple Stimulus Activity 4: Treppe 1. What do you observe? The Trace rise and fall
