1 . Describe the Major bones, muscles,joints and joint actions used to perform this movement skill and how they inﬂuence the way the body moves.
In this phase the athlete is standing in a neutral position holding the ball. The metatarsophalangeal and interphalangeal (great and lesser toes) are held at slight flexion pressed against the ground by an isometric contraction of the flexor halluces longus, flexor digitorum longus, flexor digitorum longus. The ankle is plantar flexed using an isometric contraction of the gastrocnemius and the soleus. The tibiofermoral (knee) joints are slightly flexed by a isomectric contraction of the quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius). The acetabularfemoral (hip) joint is held at a postion of slight flexion through an isometric contraction of the biceps femoris, pectineus, iliacus, and the psoas. The intervertebral (lumbar) joint is extended by an isometric contraction using the erector spinae. The atlantooccipital (cervical spine) joint is flexed by an isometric contraction erector spinae. Both scapulothroracic (shoulder girdle) joint is protracted by an isometric contraction of the serratus anterior and pectoralis minor. The glenohumeral (shoulder) joint is at internal rotation by an isometric contraction using the pectoralis major, latissimus dorsi, teres major, and the subscapularius. The humeroulnar (elbow) joint is at 90 degrees of flexion by an isometric contraction using the biceps brachii, brachioradialis, and brachialis. The radiocarpal (wrist left and right)
Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals
Shoulder flexion/extension; Elbow flexion and extension; Use of the lower and upper back. Muscles involved include the latissimus dorsi, rhomboids, trapezius, deltoids and the pectorals.
The seven organizational approaches to studying the human body include: body plans and directions, body cavities, quadrants and regions, anatomy and physiology, microscopic-to-macroscopic, body systems, and medical specialty. The body planes and directions approach is the division of the body into sections from front to back, right and left, top and bottom, along with the movement toward or away from the body planes. The Coronal Plane or frontal plane is a vertical plane that divides the body into front and back sections. The front of the body is known as the anterior or ventral section and the back of the body is
The six fundamental movements of major body segments are, abduction, extension, flexion, rotation, adduction, and circumduction. Abduction is the movement of a body part away from the midline, an example of that would be lateral raises using a dumbbell. Another example would be the lateral shuffle. It targets the muscles of the thighs, hips, and buttocks. An extension movement would be the return from flexion and an exercise for this would-be leg extensions. An example of a flexion movement is a hamstring stretch. Rotation is the circular movement of a body segment about a long axis and an example is when a tennis player hits the ball backhanded. Adduction is movement of a body part toward the midline. An example of this would be to use the
The adductors as a group are really a powerhouse. They have a lot of combined muscle fibers and through their attachment sites on the pelvis and the femur, significantly influence the body’s alignment. Because they originate and have such a presence on the pelvis, shortened adductors will influence the tilt and transverse rotation of the pelvis. The thorax is intimately connected and sometimes anchored to the pelvis through muscles such as the Quadratus Lumborum, the Rectus Abdominis and the Transverse, Internal and External Obliques. Any shift in the pelvis toward neutrality as a result of bodywork on the adductors will directly affect the muscles that connect the pelvis and the thorax and thus will create space for the thorax to shift
