| Question | Answer |
|---|---|
| O - 1st rib and costal cartilage I - inferior, lateral clavicle | Subclavius |
| Which fibers of trapezius - extend the head & neck - laterally flex head & neck to same side - rotate head and neck to opposite side - elevate & upwardly rotate scapula | Upper |
| What artery passes under pec minor? | Axillary |
| Which fibers of trapezius depress and upwardly rotate the scapula? | Lower |
| Three headed muscle of the shoulder that is an antagonist to itself... | Deltoid |
| This muscle draws the clavicle down, stabilizes the sternoclavicular joint, and elevates first rib for inhalation | Subclavius |
| O - upper 8 - 9 ribs I - medial border of scapula | Serratus anterior |
| What is the most superficial muscle of the lower back? | Latissimus dorsi |
| O - 3rd, 4th & 5th ribs I - coracoid process | Pectoralis minor |
| All of the deltoids insert into the... | Deltoid tuberosity |
| Flexing and horizontally adducting the shoulder would help you passively shorten the upper fibers of this muscle. | Pectoralis major |
| These muscles adduct (retract), elevate and downwardly rotate the scapula. | Rhomboids |
| Swimmer's Muscle | Latissimus dorsi |
| O - medial clavicle, sternum and cartilage of first six ribs I - greater tubercle of humerus | Pectoralis major |
| This muscle adducts and medially rotates the shoulder. It will help with flexing the shoulder also. | Pectoralis major |
| What nerve plexus passes under pec minor? | Brachial plexus |
| What is the most superficial muscle of the upper back? | Trapezius |
| Which fibers of trapezius adduct and stabilize the scapula? | Middle |
| The distal end of the clavicle is known as the? | Acromion process |
| The shaft of the clavicle, acromion process, spine of scapula and deltoid tuberosity are bony landmarks that will help you isolate what muscle? | Deltoid |
| Pectoralis major and lats lie superficially to this muscle. | Serratus anterior |
| O - Last six thoracic vertebrae, thoracolumbar aponeurosis, & posterior iliac crest I - lesser tubercle of humerus | Latissimus dorsi |
| O - anterior head: lateral 3rd of clavicle middle head: acromion process posterior head: spine of scapula I - deltoid tuberosity | Deltoid |
| O - spinous processes T2 to t5 I - medial border of scapula | Rhomboids major |
| What muscle does serratus anterior interdigitate with? | External oblique |
| What other muscle besides trapezius also adducts (retracts) & elevates the scapula? | Rhomboids |
| All fibers of this muscle abduct the shoulder joint. | Deltoid |
| Anterior fibers - flex, medially rotate and horizontally adduct the shoulder Posterior fibers - extend, laterally rotate and horizontally abduct the shoulder | Deltoid |
| Depresses, abducts, tilts anteriorly, and assists in forced inhalation. | Pectoralis Minor |
| O - spinous processes of C7 to T1 I - medial border of scapula | Rhomboids minor |
| Abducts (protracts) & depresses the scapula and may help in forced inhalation | Serratus anterior |
| The “little helper” that extends, adducts, and medially rotates the shoulder. | Teres Major |
| O - inferior angle of scapula I - lesser tubercle of humerus | Teres Major |
| Upper fibers of this muscle can have referrals to headaches, back & side of neck, and behind the eye. | Trapezius |
| The main muscle for shoulder extension. It also adducts and medially rotates the shoulder. | Latissimus dorsi |
| Prime protractor of scapula | Serratus anterior |
| O - Occiput, nuchal line, ligamentum nuchae and spinous processes of C7 to T12 I - Outer 3rd of clavicle, acromion process and spine of scapula | Trapezius |
| This muscle mimics a heart attack | Pectoralis major |
| Shoulder girdle refers to movement of the... | Scapula |
| Shoulder joint refers to movement of the | Humerus |
| O - transverse processes of C1 to C4 I - superior angle of the scapula | Levator scapula |
| Trapezius has the same insertion as this muscle's origin. | Deltoid |
| The clavicle, scapula and the humerus all make up the... | Shoulder girdle |
| The shoulder joint is also called the... | Glenohumeral joint |
| Supraspinatus, Infraspinatus, Teres minor and Subscapularis are part of what group? | Rotator cuff |
| Supraspinatus, Infraspinatus & Teres minor all insert onto this bony landmark. | Greater tubercle |
| What rotator cuff muscle abducts the shoulder? | Supraspinatus |
| Levator scapula _________ the scapula. | Elevates |
| Prime mover or agonist for supination of the forearm? | Biceps brachii |
| Prime mover or agonist of elbow extension? | Triceps brachii |
| O - infraspinous fossa I - greater tubercle of humerus | Infraspinatus |
| O - 1st to 4th cervical transverse processes I - superior angle of the scapula | Levator scapula |
| O- long head: infraglendoid tubercle of scapula lateral head: posterior, proximal humerus medial head: posterior, distal humerus I - olecranon process | Triceps brachii |
| O - coacoid process of scapula I - medial middle humerus | Coracobrachialis |
| This artery is an extension of the axillary artery. It runs between biceps & triceps brachii. | Brachial |
| O - subscapular fossa I - lesser tubercle of humerus | Subscapularis |
| This rotator cuff muscle does not actually rotate the shoulder. | Supraspinatus |
| Coracobrachialis can _________ & ________ the glenohumeral joint (shoulder). | Flex & adduct |
| Prime mover or agonist for scapular protraction. | Serratus anterior |
| Rhomboids and Serratus anterior are ________ to each other. | Antagonist |
| This muscle has 3 sections: clavicular, sternal & costal. | Pectoralis major |
| The glenohumeral joint is stabilized by what group of muscles? | Rotator cuff |
