Name the muscle that has its proximal attachment (origin) on the supraspinous fossa:
Supraspinatus
The muscle which that has its proximal attachments (origin) on the supraglenoid tubercle and also on the coracoid process of the scapula is the:
biceps brachii
Which muscle from the list below has its proximal attachment (origin) on the lower lateral border and inferior angle of the scapula:
teres major
All of the following are members of the rotator cuff EXPECT:
teres major
All of the following muscles are capable of externally (laterally) rotating the shoulder at the glenohumeral joint EXCEPT:
subscapularis
What are the concentric actions of the muscle that has its proximal attachment (origin) on the medial half of the clavicle, the sternum, and the cartilages of upper eight ribs, and its distal attachments (insertion) on the humerus next to the distal attachment (insertion) of the latisimus dorsi?
adduction, horizontal adduction, internal (medial) rotation and assists with flexion of the humerus
Which muscle's primary action is to depress and abduct the scapula and due to it's anatomical position, may also entrap the brachial plexus nerves?
pectoralis minor
Extension of the shoulder at the glenohumeral joint takes place in which plane?
sagittal
The levator scapulae has it's origin at the transverse processes of C1-C4 and it's insertion at the superior angle of the scapula
true
What is the PRIMARY CONCENTRIC ACTION of the muscle that has its proximal attachment (origin) on the occiput, ligamentum nuchae, and the spinous process of C7 and its distal attachment (insertion) on the clavicle, scapular spine and acromiun process?
scapular elevation
The PRIMARY CONCENTRIC ACTION of the muscle that has its proximal attachment (origin) on the anterior shaft of the humerus (lower half) and its distal attachment (insertion) on the coronoid process and tuberosity of the ulna is:flexion of the elbowThe PRIMARY CONCENTRIC ACTION of the muscle that has its distal attachment (insertion) on the olecranon process is:extension of the elbowWhich muscles are part of the force couple that work together to rotate the glenoid fossa superiorly, a motion also know as upward rotation of the scapula?upper and lower trapziusThe muscle that has its proximal attachment (origin) on the lateral supracondlyar ridge and its distal attachment (insertion) on the styloid process of the radius is the:brachioradialisWhich of the following is a member of the superficial flexor pronator mass/superficial forearm muscle group?pronator teresWhat muscle has its proximal attachment (origin) above the medial epicondyle of the humerus, on the coronoid process of the ulna, and the common flexor tendon?Pronator teresWhich statement is true?-The elbow is distal to the wrist -the brachialis is deep to the biceps brachii tendon at the elbow -the flexor digitorum superficialis is deep to the flexor digitorum profundus -the unlar groove lies on the lateral aspect of the elbow posterior to the lateral epicondyle -the brachialis is deep to the biceps brachii tendon at the elbowThis muscle's distal attachment (insertion) is primary on the pisiform bone, plus with ligaments to the hamate and base of the 5th metacarpal:flexor carpi ulnarisWhich muscle does not have a proximal attachment (origin) on either epicondyle of the humerus?-pronator teres -supinator -flexor digitorum superficialis -flexor digitorum profundus -flexor digitorum profundusAll of the following muscles flex the wrist EXCEPT:-flexor carpi radialis -flexor carpi ulnaris -flexor digitorum -brachioradialis -brachioradialis
