Endomysium- covers the individual muscle fibers Sarcomere- smallest contractile element of muscle fiber‚ extends from z-line to z-line Myofilament- responsible for contraction Striated- the color variations on the muscle fiber. Has to do with the amount of protein and the way it reflects light. Myosin- globular protein Bulb like heads come in contact with the active sites on actin Active sites are not exposed when in the resting position

Relatively speaking‚ biceps and triceps are small muscle gourps 2. Your biceps are heavily stimualted every time you perform a basic pulling movement for your back 3. Your triceps are heavily stimulated every time

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
