| Question | Answer |
|---|---|
| which 2 muscles as a sole action, rotate the arm laterally, and then which of these has an origin of the lateral border of the scapula and an insertion greater tubercle of the humerus. | Infraspinatus and Teres Minor |
| This muscle flexes and adducts the arm and has the insertion of the shaft of the humerus and its origin is the coracoid process of the scapula | coracobrachialis |
| This muscle has the origin of the ocipital bone and spines of the cervical and thoracic vertebra, and an insertion of the clavicle spine and acromian process of the scapula | Trapezius |
| This muscle elevates the scapula, and has the origin of the transverse processes of the cervical vertabrae and the insertion of the medial margin of the scapula | Levator scapula |
| The muscle abducts,extends,and flexes the arm | Deltoid |
| This muscle has an origin of the acromion process, spine of scapula and the clavicle | Deltoid |
| This muscle extends, adducts and rotates the arm medially, or pulls the shoulder downward and back with the origin point of the spines of the sacral, lumbar and lower thoracic vertebrae iliac crest and lower ribs | Latissimus dorsi |
| this muscle has the origin of the sternal ends of the upper ribs, an insertion of the coracoid process of the scapula and pulls the scapula forward and downward or raises ribs. | Pectoralis minor |
| This muscle the sole function of rotating the arm medially | Subscapularis |
| This muscle is one which raises and adducts the scapula with the insertion of the medial border of the scapula and an origin of the spines of the upper thoracic vertebrae | Rhamboideus Major |
| This muscle extends, adducts, and rotates the arm medially with the insertion of the interbercular groove of the humerus and an origin of the lateral border of the scapula | Latissimuss Dorsi |
| This muscle has an origin of the outer surface of the ribs | Serratus Anterior |
| Muscle used when weight lifting and doing bench pressing | Pecoralis minor |
| This muscle has an origin of the clavicle, sternum, and costal cartilages of the upper ribs with and insertion of the interrubercular groove of the humerus and flexes,adducts,rotates the arm medially | Pectoralis major |
| This muscle has a sole function of abducting the arm | Supraspinatus |
| This muscle has an origin of the posterior surface of the scapula above the spine and its insertion is the greater tubercle of the humerus and abducts the arm | Supraspinatus |
| This muscle is one of the two muscles in wich sole function is to rotate the arm laterally, but has an origin of the posterior surface of the scapula below the spine | Infraspinatus |
