ball. Backswing is the technique to balance the body while kicking. For leg cocking‚ hip have centric contraction before eccentric contraction. Proximal distal of skill‚ hip need to extend to the phase up and flexion. On the initial step‚ it will be hip extension‚ knee flexion‚ planta flexion and hip external rotation. On the leg cocking it involve with internal rotation of gluteus. It must have varitation of changing in hip and knee before it get contact with the ball. During contact‚ it need power

the knee requires flexion‚ extension‚ rotation and the arthrokinematic motions of rolling and gliding • Rotational component involves the “screw home mechanism” – As the knee extends it externally rotates because the medial femoral condyle is larger than the lateral – Provides increased stability to the knee – Popliteus “unlocks” knee allowing knee to flex © 2011 McGraw-Hill Higher Education. All rights • Capsular ligaments are taut during full extension and relaxed w/ flexion – Allows rotation

canal during rapid neck bending. In experimental neck trauma research on animals‚ pressure gradients were observed and indications of nerve cell membrane dysfunction were found in the cervical spinal ganglia. The experiments covered neck extension‚ flexion and lateral bending. A theoretical model in which fluid flow was predicted to cause the transient pressure gradients was developed and a neck injury criterion based on Navier-Stokes Equations was applied on the flow model. The theory behind the Neck

Evaluate how the name of a muscle can distinguish its location‚ action‚ shape‚ and function. Select five different muscles to make this distinction. Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone‚ but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions‚ like the genioglossus

Absence of Local Sign Withdrawal in Chronic Human Spinal Cord Injury Spinal cord • Main pathway of communication between the brain and the rest of the body. • Soft tube-like structure of nerves that extends downward from the base of the brain. • Protected by the bones of spinal column. - Nerves enter and exits from the spinal cord through its length‚ passing through small openings between each vertebra. • It is highly organized. - Anterior motor neuron

movable joints. These types of synovial joints are the largest group with the greatest variations and can be found in the shoulder or hips. Some examples of these include the hips‚ wrists and elbows and shoulders. Movements that these joints allow are flexion and extension‚ and rotational movement. The components of synovial joints include cartilage to reduce friction and absorb shock‚ synovial fluid to lubricate the joints‚ synovial membrane which produces this fluid‚ tendon which joins the muscle
