The 17 muscles attached here fix the scapula to the thoracic wall and allow it to move. Four muscles, namely subscapularis, infraspinatus, teres minor, and supraspinatus, form the rotator cuff, covering the shoulder capsule. These muscles are listed below and classified based on whether they originate from the scapula or insert into it.sectional anatomy chapter 9 &10. The infraspinatus tendon inserts on the?

The suboccipital region is a muscle compartment, located inferior to the external occipital protuberance and the inferior nuchal line. These are anatomical landmarks on the occipital bone of the skull. It is of a pyramidal shape and includes the posterior aspects of the atlas and axis (C1 and C2 vertebrae respectively).triceps brachii. The primary action of muscle on the medial compartment of the thigh is ________. adduction of the thigh. Brachioradialis and sternocleidomastoid are named for ________. the location of their origin and insertion. This pair of muscles includes the prime mover of inspiration, and its synergist.The infraspinatus muscle is situated under the scapular spine in the infraspinous fossa and inserts into the greater tuberosity of the humerus. It is a component of a crucial shoulder muscle group, the rotator cuff. There are a few interesting additional muscles in the infraspinal region. In the literature they are called the infraspinatus superficialis, infraspinatus minor and infraspinatus ...
Infraspinatus inserts here on the back of the greater tubercle, teres minor just below it. Both these muscles produce external rotation of the humerus. These four short muscles, subscapularis, supraspinatus, infraspinatus, and teres minor, converge on the humerus to form an almost continuous cuff of flat, supporting tendons, often referred to ...A full-thickness tear is when the wear in the tendon goes all the way through the tendon. Partial tears can be just 1 millimeter deep (only about 10 percent of a tendon), or can be 50 percent or deeper. When a radiologist looks at an MRI scan, he or she must make a judgment about the type of the rotator cuff changes.…

Fig. 2. The intramuscular tendons of the infraspinatus muscle were counted in a vertical line (dashed above the arrow) midway between the glenohumeral joint space (left-most line) and the insertion of the muscle (right-most line) in the coronal view. The line above the arrow was labeled "the lateral measuring point".Purpose: High-grade partial thickness rotator cuff tears (i.e., those involving at least 50% of the tendon thickness) are especially challenging to treat and various treatment strategies have been described. Prior studies have demonstrated equivalent outcomes between in situ tear fixation and tear completion repair techniques. However, it is unknown how repair of completed high-grade partial ...
