Scapula Research Paper

It's function is to hold the tendons in position. It's dysfunction can cause is tenosynovitis and carpal tunnel syndrome.

Consists of the scapula and the clavicle (shoulder girdle). It attaches the upper appendages to the skeleton and is a major attachment for the major muscle of the neck and trunk.

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.

There are many more terms and concepts in throwing a baseball then the 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 of the rotator cuff is for the stability of the shoulder joint. It holds the humeral head in the glenoid socket during early abduction while throwing. (" biomechanics of," ).

Speech may be slurred and facial expressions may be limited, making it hard to smile. It may be difficult to hold head up due to weak neck muscles. Weak limb muscles cause difficulty walking, climbing stairs, lifting objects, or holding arms up. Raising the body from a seated position may cause difficulty. Chest muscles may also be affected, causing difficulty with breathing. This particular symptom may cause serious problems, called a myasthenic crisis

Dynamic scapular dyskinesis is detected by asking the patient to raise and/or abduct both arms repeatedly in a rhythmic motion, until fatigue of the scapular stabilizers results in failure to keep the scapula well positioned in relation to the thoracic wall. Active scapular retraction and elevation are checked. The next step is to look for muscle atrophy and remember active and passive range of motion should be examined and compared with the non-injured shoulder. It is easy to detect muscle atrophy of the infraspinatus viewing from the back of the patient, whereas the supraspinatus is covered by the trapezius. Atrophy of the shoulder muscles is a common finding in patients with rotator cuff tears.

Comparing deltoid and lumbar muscle activation is an unfair advantage in favor of the Shake Weight, as the shoulder position is different. The Shake Weight model has the arms elevated while the dumbbell model has her elbows at her sides. By default, the anterior deltoids and the muscles of the lower back will have a greater contraction.

The intended action for the upper part of this muscle is to elecate the scapula and extend the head at neck. The intended action for the Middle part of this muscle is to create elevation upward rotation and adduction of the scapula. The intended action for the lowerpart of this muscle is to create depression adduction, upward rotation of the scapula. Workouts that target these areas would be Barbell Shrugs, Cable shrugs and Dumbbell Shrug.

Scabies is an itchy skin condition caused by the microscopic mite, Sarcoptes scabei. It is common all around the world, and can affect any one. Scabies spreads quickly in places such as hospitals, child-care centers, and nursing homes. This occurs because of crowded conditions where there is often skin-to-skin contact between people. Scabies can easily be transferred by household members. Sharing bedding, towels, and clothes can usually spread scabies. This can occur more easily when the infested person has crusted scabies, a severe form of scabies caused by delayed treatment of the infestation, mite-filled wounds covered by scabs. Scabies cannot be acquired by a pet because they get a different mite infection called "mange." Therefore, Scabies is a highly contagious and intensely itchy infestation that can be prevented and treated.

Scabies is a major global health problem caused by the mite Sarcoptes scabiei var. hominis, an obligate human ectoparasite measuring between 330 and 450 µm in length. Treatment of this disease has undergone various changes from the days of Roman physician Celsus, when sulphur mixed with liquid pitch was used as a primary approach.

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

I have chosen the constellation Scorpius. I chose Scorpius because it is one of the most interesting looking constellations (in my opinion), and it contains many bright stars. Scorpius means scorpion in Latin, and it is a zodiac sign, although its name is changed to Scorpio. It is in the southern hemosphere, and it lies between Sagittarius and Libra.

For shoulder flexion 61% of the variance could be accounted for by the sit-and-reach. A correlation was also found between the modified sit-and-reach test and both the shoulder extension and hip flexion tests. For shoulder extension 33% of the variance was accounted for by the modified sit-and-reach and for hip flexion 22% of the variance was accounted for by the modified sit-and-reach.

This causes these muscles to become stronger. When this happens, you’re posture is affected. The body is not aligned correctly which may cause injury down the road. Many simple routines of stretching can correct this misalignment and make you feel much better.

The main aim was to see if scapula-stabilising exercises could influence the velocity and accuracy of the tennis serve. This experiment focused on recreational tennis players due to limited research in this area of tennis.
