Muscle attachments
| Question | Answer |
|---|---|
| The two muscle attachment sites of the clavicle are? | Sternal extremity(medial), Acromial extremity(lateral) |
| What is the ligament attachment site on the clavicle called? | Conoid tubercle |
| Name the 12 muscle attachment sites on the scapula. | Coracoid process, Spine, Glenoid cavity, Subscapular fossa, Medial margin, Lateral margin, Superior angle, Inferior angle, Supraspinous fossa, Infraspinous fossa, Supraglenoid tubercle, Infraglenoid tubercle |
| What is the most lateral and superior landmark on the scapula? | The Acromion |
| Name the 7 muscle attachment sites on the humerus. | Greater tubercle, Lesser tubercle, Intertubercular groove, Deltoid tuberosity, Medial epicondyle, Lateral epicondyle, Olecranon fossa |
| Name the 2 muscle attachment sites on the ulna. | Coronoid process, Olecranon |
| Name the ligament attachment on the ulna. | Styloid process |
| Name the 2 muscle attachment sites on the radius. | Radial tuberosity, Styloid process |
| What is the proximal (origin) attachment of Pectoralis major (sternal head) | Sternum, Costal Cartilages 1-6 |
| What are the proximal attachments of Latissimus dorsi (coughing muscle)? | T6-S5 vertebrae, Illiac crest, Ribs 9-12 |
| Name the 3 functions of the deltoid | prime mover of abduction of should joint, strong flexor of humerus, extension of shoulder, lateral rotation and medial rotation |
| Name the four rotator cuff muscles | Teres minor, infraspinatus, supraspinatus, subscapularis |
| Proximal attachments for Trapezius | Posterior skull, C7-T12 vertebrae |
| List 2 structures that attach to the coracoid process | coracoid humeral ligament, coracoidclavicular ligament |
| The "crank like" shape of the clavicle functions to....? | Increase shoulder region mobility. Amplify greater rotation movement of shoulder |
| Eccentric muscles work to control or slow effect of gravity, thus it works to provide what sort of muscle contraction? | Muscle lengthening |
| Muscles with parallel form are better adapted to produce: | movements of large range |
| Name 3 structural differences between skeletal muscle cells and smooth muscle cells: | smooth muscle cells have a single nuclues - skeletal muscle cells have several nuclei; myofilaments in smooth muscle are not arranged in sarcomeres; smooth muscle cells contain a 3rd type of contractile protein (desmin) |
| Name the 3 muscles that join to the coracoid process | Pectoralis minor, biceps brachii and coracoidbrachialis |
| What contributes to the stability of the radioulnar joint? | interosseous membrane, collateral and annular ligaments, articular disc, and pronator quadratus |
| Name the proximal attachments for biceps brachii | coracoid process, superglenoid tubercle of scapula |
| Name the proximal attachments for rhomboid major | T2-T5 vertebrae |
| Name the proximal attachments to rhomboid minor | C7-T1 vertebrae |
