The flexors of the leg include all of the following except the: Question 29 options:   biceps femoris   rectus femoris   semimenbranosus   semitendinosus   saritorius Question 30   The muscle fiber arrangement of the rectus femoris is: Question 30 options:   bipennate and has greater potential for force   bipennate and creates tension through a greater range   fusiform and creates tension through a greater range   fusiform and has greater potential for force.

Why does the contraction of one head of biceps femoris flex the knee and extends the hip while the other head can only flex the knee?

If your biceps brachii muscle attaches to your forearm 2 inches below your elbow, the distance from the elbow to the palm of your hand is 18 inches, and you lift a 20 pound weight, how much pull must your muscle exert to achieve elbow flexion?

During a Physical Education class, you ask your students to perform a standing vertical jump. Identify the type of muscle contraction involved in the jump and describe the movement patterns of the concentric and eccentric phases. Outline the agonists, antagonists and synergist muscles, which contribute to maximum jump height. Identify the major lower body joints and joint movements, which contribute to the concentric phase of the jump.

The right levator scapula is contracted with the intent to only elevate the scapula, no other actions at the scapula are desired. Please complete the following two part question What are all of the muscles that could act as a synergist/neutralizer during this motion? What muscle would be the best option for a synergist/neutralizer and justify your answer?

With the paired muscles along the spine, a more origin (attachment) will allow the muscle to generate more rotation and/or lateral flexion when only one side of the paired muscle is activate.

Identify the muscles that are involved in the following movements: Knee Extension Knee Flexsion Knee Fyten
