Skeletal Muscle Physiology: Activity 3: The Effect of Stimulus Frequency on Skeletal Muscle Contraction Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. 1. During a single twitch of a skeletal muscle Your answer : a. calcium is not released from the sarcoplasmic reticulum. Correct answer: b. maximal force is never achieved. 2. When a skeletal muscle is repetitively stimulated‚ twitches can overlap each other and result in a stronger muscle contraction

extension is the movement of straightening the leg at the knee joint. The major muscle involved in knee extension is the Quadriceps femoris‚ which is a group of four muscles. These four separate muscles of the Quadriceps femoris are the Vastus lateralis‚ Vastus medialis‚ Vastus intermedius‚ and Rectus femoris. These muscles‚ along with synergists‚ work together to perform knee extension for a vertical jump. Each of the muscles of the Quadriceps femoris have different origins‚ however they all share a

They are postural synergy which is automatic and unconscious muscle activity. Then there is voluntary synergy which is the opposite‚ intentional activity. The researchers found out that dancers altered voluntary synergies involved in the performance of a selected dance movement. The conclusion of this study was stated

muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with
