What Makes A Gardener, An Athlete And A Carpenter

It is the largest bone in the arm. It is also the only bone in the upper arm. The humerus is connected to many parts such as muscles that help move the shoulder and the elbow. The humerus is so important to many types of actives such as texting, eating and cocktail shaking. The humerus is at the proximal end. The end of the humerus is smooth and round. Because it forms a ball it is connected to the shoulder to form a ball and socket joint. The glenoid cavity of the scapula acting at the socket because of this the humerus can move n full circles and rotate at the shoulder joint. The humerus is a long bone we know this because it is longer than it is wide. It is also a hollow bone which is supported inside by small layers of spongy bone also

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)

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.

Biceps Brachii - It's attachments are the coracoid process, supraglenoid tuberosity, and radial tuberosity. When it contracts it causes flexion and supination. It's located close to the endangerment site the antecubital. This area is known for housing chronic pain.

Four muscles that are attached to the shoulder blade make up the rotator cuff. These muscles work together to ensure the shoulder moves and rotates properly. If the muscles become inflamed or torn, you will struggle

The labrum is a rim of soft tissue that makes the socket into more of a bowl-like shape. The labrum transforms the hard, angled surface of the glenoid into a deeper socket that molds to fit the head of the humerus. When the head of the humerus doesn't fit into the socket, this is when one will experience problems. The rotator cuff connects the humerus to

The rotator cuff refers to the group of muscles and tendons in your shoulder that connects your shoulder blade to your upper arm.

This paper is going to be over rotator cuff injuries and what to do if this occurs to an athlete. The rotator cuff consists of four muscles which are the Subscapularis, infraspinatus, teres minor, and the supraspinatus and their associated tendons that insert into the Humerus. These groups of muscles are responsible for rotating the arm internally and externally as well as abducting the shoulder. The acronym for the four muscles of the rotator cuff is known as SITS. The best treatment for symptomatic, nontraumatic rotator cuff tears is unknown. The purpose of this trial was to compare the effectiveness of physiotherapy, acromioplasty, and rotator cuff repair for this injury. The way this trial worked was that 180 shoulders with the symptomatic,

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," ).

RCT is a common disease. According to general population surveys, the prevalence of rotator cuff tear is 25 % in those older than 50 years of age and 20 % in those older than 20 years of age (1). The rotator cuff is a group of 4 muscles and their tendons supraspinatus, infraspinatus, teres minor, and subscapularis (2). These muscles connect the upper-arm bone, or humerus, to the shoulder blade. The important job of the rotator cuff is to keep the shoulder joint stable. RCT can be caused by degenerative changes, repetitive micro-traumas, severe traumatic injuries, and secondary dysfunctions. Falling on an outstretched hand, unexpected force when pushing or pulling or during shoulder dislocation can cause traumatic injury to the rotator cuff.

Millions of people across the United States suffer from either Bursitis or a rotator cuff injury every year. Although sometimes the two can be misconceived, they are very different in all actuality. Bursitis is the inflammation or irritation of the bursa. A bursa is a fluid-filled sac used as a bumper near the joints to reduce friction. There are many bursae located in your body, some of which being in the hip, shoulder, wrist, and elbow. However, a rotator cuff injury only affects the shoulder area of the body. The “rotator cuff” is composed of the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. There is only one main way to be diagnosed with Bursitis and it happens when you overuse a joint in sports or on the job. You can put the bursa under pressure for a long time, thus causing the bursa to become inflamed.

The rotator cuff is a group of 4 muscles, the supraspinatus, infraspinatus, subscapularis, and the teres minor. These muscles helps to lift your shoulder up over your head and also rotate it toward and away from your body. Unfortunately, it is also a group of muscles that is frequently injured by tears, tendonitis, impingement, bursitis, and strains. The major muscle that is usually involved is the supraspinatus muscle. Rotator Cuff Injuries are usually broken up into the following categories.

For example, people who play volleyball tend to get supraspinatus tendonitis because they have to constantly raise their hand and apply force to the volleyball. Other hobbies like weightlifting, swimming, rowing, painting, and tennis are all activities that can cause supraspinatus tendonitis because it makes it more likely for the supraspinatus to pass under the acromion. Although this condition occurs more often in athletes and active individuals, people who are between 30 to 60 years old also commonly get this condition as well. Older people get supraspinatus tendonitis, due to supraspinatus tendinosis, which is when there is chronic degeneration without any inflammation. This can cause supraspinatus tendonitis because this condition can occur over time and slowly weaken the shoulder. Additionally, any long term joint disease like like osteoarthritis can cause supraspinatus tendonitis in older individuals because it can also abate the

^8,5 ASI occurs when the arm is in adduction with the shoulder internally rotated. The biceps complex pulley, also known as a capsuloligamentous complex, adjoins the anterior glenoid causing injury when in extreme motions. With the PSI, the pulley is put into risk with abduction and external rotation on the posterosuperior glenoid. ^8 PSI is also associated with partial-thickness tears on the deep side of the articular surface of the rotator cuff. ^5 This can be a common cause for a peel-back mechanism associated with a SLAP lesion. ^8 Peel-back mechanisms can be produced many different ways, but are mostly seen with a SLAP lesion or internal impingement. These can occur when the shoulder is placed into abduction and extreme external rotation with a torsional force added to the labro-bicipital complex that is at the base of the biceps on the posterior superior labrum. ^1,5 This causes fatigue and failure of the humeral head that rotates medially over the upper rim of the glenoid fossa creating a shearing force. ^1,5 Increased superior labral strain in overhead athletes occurs during the late-cocking phase of throwing when arm is externally rotated. ^1

Shoulder injuries are a very common injury that occurs in most sports. All injuries and the rehabilitation done to the injured shoulder are based on the anatomy and structures of the shoulder. Doctors have developed different tests for evaluating the degree and seriousness of injured shoulders. Some have also developed different phases a person must go through to properly rehabilitate the shoulder.
