Humerus

The UCL is crucial for valgus stability, maintaining the appropriate angle of the elbow away from the body, of the elbow and is the primary elbow stabilizer. As stated in Haan et al. (2011), “the AMCL is divided in two functional components and is taut throughout the full range of flexion and extension because the components are alternatively tightening throughout this range of motion. The posterior part of the AMCL is taut from eighty degrees flexion to full flexion; in contrast, the anterior part

choose. Seeing that rotator cuff tendinitis is very frequently diagnosed, I was interested to learn more about it and what makes it so common.     A shoulder is one of the most complex  joints of the body. The anatomy of the shoulder starts where the humerus fits into the scapula almost as if it were mimicking a ball and socket. The scapula has a little tip of itself overlooking the tendons of the shoulder called the acromion and a bit of itself fanning out, a part called the coracoid. Also connected

frequently injured, with most individuals injuring one or more parts of the shoulder during their lifetime. The Makeup Of The Shoulder The shoulder consists of three separate bones: the scapula or shoulder blade, the clavicle or collarbone and the humerus or arm bone. Most people only associate the shoulder blade with the shoulder, yet all three parts work together to ensure proper functioning, and the shoulder also contains tissues to ensure the joint works as intended. This includes muscles, tendons

Rotator Cuff Surgery Your rotator cuff consists of four muscles in your shoulder that allows you to move your arm away from your body. These muscles have tendons, which connect them to the head of your upper arm bone or humerus. When a tear occurs in these muscles, you will experience extreme pain on motion. A rotator cuff tear is also extremely painful at night. If left untreated, it may result in arm weakness. Rotator cuff surgery may be required to repair re-attach torn tendons to the shoulder

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. The overarm throw is a skill frequently used in a wide range of sports such as cricket,softball and baseball. The action is also used in athletic activities such as javelin, with the overhead serve and smash in tennis, volleyball and badminton and passing a netball and basketball.An overarm throw is the action of the arm swinging backwards then upwards

wind-up, cocking, acceleration, and the follow through. There is also the stride, your pelvis, rotation, deceleration, force, gravity, resistance and speed. (Maranowski). Within the shoulder, there are three major bones used. They are the clavicle, humerus, and the scapula. Another major component of the shoulder while throwing is the rotator cuff. The rotator cuff is made up of four small muscles which are the subscapularis, supraspinatus, infraspinatus, and the teres minor. The main responsibility

The deltoid has three main functions that involve the three individual muscle “strands”. The the anterior deltoid rotates the humerus anteriorly, such as when you reach forward or throw a ball underarm. The lateral deltoid rotates the arm directly out sideways using abduction. The posterior deltoid extends the arm backwards and laterally rotates the arm by pulling the humerus toward

Shooting a bow largely involves the use of the upper extremity. Between the needs of stabilization and torque, many muscles in the upper extremity are utilized to perform an effective shot. However, the lower extremity is also involved in bow shooting mechanics. Muscles in the lower extremity perform both concentric and eccentric contractions to stabilize the body during all phases of shooting a bow. Therefore, shooting a bow involves complex contractions of muscles throughout the body. In

Assignment title: Functional Anatomy Individual Assignment 2 exercise movement with diagrams and full anatomy Introduction The shoulder joint is also know as the glenohumeral joint is a “ball and socket” between the head of the humerus and the glenoid cavity of the scapula bone(shoulder blade). The six main movements of the shoulders are: flexion, extension, abduction, adduction, internal rotation and external rotation. Flexion is when the upper arm is elevated forward toward the

It originates from the inferior thoracic and lumbar vertebrae, sacrum, iliac crest, and the four most inferior ribs, runs laterally up through the back, inferior part of shoulder blades and inserts to the upper front of the humerus. This muscle plays a role in shoulder joint movement such as adducting the arms, extending the shoulders and rotating shoulder joints medially. Tight latissimus dorsi and the trigger points in the muscles could be one of the causes of shoulder pain
