The American Council on Exercise states that the rotator cuff, in the shoulder, is made up of four muscles: the infraspinatus, the teres minor, the subscapularis, and the supraspinatus. Each of these muscles is individually responsible for a...
The shoulder is a ball-and-socket joint, which gives it a full range of motion and high flexibility. The tendons in the shoulder are used both for movement and stability, and they assist the labrum--a cap of connective tissue--in keeping the head...
The rotator cuff is actually the tendon of four separate muscles: the supraspinatus, infraspinatus, subscapularis and teres minor. The shoulder joint is a ball-and-socket joint and these four muscles cover the ball portion of the joint. The four...
Your rotator cuff comprises four tendons -- the subscapularis, supraspinatus, infraspinatus and teres minor -- that encircle the shoulder joint. These tendons stabilize your shoulder and assist in the various movements that rotate the shoulder...
Injuries to the rotator cuff occur in a spectrum ranging from mild inflammation to complete destruction of the shoulder. Pain can be present in the shoulder with any of the conditions. The range of motion of the shoulder may be decreased in any...
Your supraspinatus is a muscle in your shoulder that forms part of a structure called the rotator cuff. This structure is responsible for keeping your upper arm bone, or humerus, in its socket, as well as connecting your humerus to your shoulder...
The supraspinatus is one of four tendons that help make up the rotator cuff. The other tendons are the infraspinatus, subscapularis and teres minor. The distal supraspinatus attaches to the top of the upper arm bone and aids in extending the arm...
The rotator cuff is susceptible to injury if you play sports that require overhead arm movements, such as baseball, softball, swimming, tennis and volleyball. A rotator-cuff strengthening program is a critical part of a sport-specific...
Sometimes called swimmer's shoulder or thrower's shoulder, impingement syndrome is a shoulder joint problem caused when the four tendons of the rotator cuff-- the supraspinatus, infraspinatus, teres minor and subscapularis -- become trapped in the...
The shoulder joint is an amazingly complex structure with many muscular attachments that enable it to move in multiple directions. When the structures surrounding the shoulder are strong and balanced, the muscles are capable of generating great...
Tendons are tough bands of inelastic fibrous tissue that connect muscle to bone. Every movement in the body depends on the ability of tendons to stretch and retract on demand. Tendons create motion. Tendons are not to be confused with ligaments,...
The rotator cuff is a critical component of the shoulder that takes part in almost every movement of this joint. As described in an article published in "American Family Physician," the rotator cuff is composed of four muscles--the subscapularis,...
The rotator cuff is made up of four tendons--the supraspinatus, infraspinatus, teres minor and subscapularis. These originate from the shoulder blade and attach to the humeral head (the top of the arm bone, which moves against the glenoid portion...
Your rotator cuff is a group of four muscles and their tendons -- supraspinatus, infraspinatus, teres minor and subscapularis -- that help stabilize your shoulder. The American Academy of Orthopaedic Surgeons states that tears in your rotator cuff...
The rotator cuff is composed of the following muscles and their associated tendons: supraspinatus, infraspinatus, teres minor and subscapularis. According to the MayoClinic.com website, rotator cuff injuries irritate or damage the rotator cuff...
Your rotator cuff is a group of muscles and tendons that helps hold your shoulder joint together and also helps you rotate and lift your arm. Tears in your cuff can develop gradually over time or occur quickly as a result of a traumatic injury. As...
Your rotator cuff consists of four muscles--supraspinatus, infraspinatus, teres minor and subscapularis--and the tendons that attach them to the bones. The muscles and tendons connect the upper arm bone, or humerus, to the scapula, or shoulder...
The shoulder is a mechanically sophisticated joint formed by the junction of three bones and several muscles, ligaments, tendons and bursae. The complexity of the shoulder enables its remarkable range of motion, but also leads to injury...
The challenge in defining a rotator cuff tear lies in its symptoms. According to Sport Med Center, the symptoms of a tear do not differ from those of rotator cuff tendinitis and impingement syndrome or other injuries to the shoulder.
According to the textbook "Basic Biomechanics," your rotator cuff includes the tendons of the subscapularis, supraspinatus, infraspinatus and teres minor muscles, which attach to your shoulder joint. These muscles function to rotate your humerus...
The elbow and shoulder are common areas injured while playing golf. Overtraining, muscle tightness and poor swinging technique may lead to injuries like golfer's elbow and a rotator cuff tear. Signs of an injury are objective findings that are...
Strength training should be a regular part of your exercise routine, with the Centers for Disease Control and Prevention suggesting that all adults get at least two days of strength training exercise each week. Strength training helps build...
Yoga exercises can improve the strength and flexibility of your rotator cuff muscles. Strong rotator muscles are less likely to tear or develop shoulder impingement syndrome, bursitis or tendonitis. The rotator muscles include the supraspinatus,...
The rotator cuff is a collection of small muscles and tendons that surround the joint of the shoulder. When the tendons of the rotator cuff become inflamed and irritated from overuse, tendonitis can develop. Along with pain in the shoulder, this...
The glenohumeral joint is where the top of the arm bone (humeral head) meets the glenoid portion of the shoulder blade. The acromioclavicular joint is where the collarbone (clavicle) meets the acromion portion of the shoulder blade. The...
When a shoulder muscle or tendon in the rotator cuff tears, people lose both strength and range of motion. Shoulder function can diminish greatly due to inflammation and tissue damage, especially if the injury affects the bones or nerves as well....
The rotator cuff consists of a group of muscles and tendons surrounding the shoulder joint. You may experience pain and difficulties in raising and rotating your arm with tendon injuries. Injuries to rotator cuff tendons can develop through wear...
This rotator cuff is made up of tendons and four muscles known as the supraspinatus, infraspinatus, teres minor and subscapularis. According to the American Academy of Orthopaedic Surgeons, traumatic injuries and consistent overhead motions are...
