Review Upper Extremity

Shoulder

100

the SIT muscles of the rotator cuff all attach to this bony prominence

greater tuberosity

200

this structure in the shoulder helps resist too much translation of the humerus and helps deepen the joint socket

glenoid labrum

300

This muscle assists the deltoid in abducting the shoulder and is also most active during first 30 degrees of abduction (hint: muscle is in subacromial space)

supraspinatus

400

an abnormality in the coordination of the glenohumeral and scapulothoracic joints results in this

scapular dyskinesis

500

this muscle inserts here as shown, to depress the scapula but it primarily works to internally rotate, extend and adduct the glenohumeral joint

latissimus dorsi

Elbow

100

This ligament helps stabilize the radius against the ulna

annular ligament

200

these two actions occur at the radio-ulnar joints

pronation and supination

300

Normal elbow range of motion is from 0 degrees of extension to ________________ degrees of flexion

150

400

this is the anatomical name for the "elbow" joint

humero-ulnar

500

The ulnar nerve can be found between which two bony landmarks

medial epicondyle and olecrannon

Wrist and Hand

100

this bone is the most commonly fractured but hard to heal carpal bone

scaphoid

200

This structure is formed by the flexor retinaculum making the "roof" and the carpal bones making the "floor" of it

carpal tunnel

300

this structure increases the articulation between the ulna and the lunate/triquetrum

TFCC

400

this part of the metacarpal is also referred to commonly as the knuckle

head of the metacarpal

500

a muscle that originates on the forearm but inserts onto the hand or wrist to work the radio-carpal joint is said to be _____________________

extrinsic

Muscles

100

This muscle flexes both the shoulder AND the elbow

bicep brachii

200

this is the only rotator cuff muscle that does internal rotation

subscapularis

300

this is the origin of this muscle shown in red

coracoid process

400

the main action of this muscle shown here is

scapular protraction

500

This muscle of the elbow is a weak extensor and assists the tricep brachii

Anconeus

Anything Goes

100

this is the joint that is being bent

PIP joint of 5th digit

200

this is the bone developing Kienbock's disease

lunate

300

this part of the humerus articulates with the radial head

capitulum

400

This bursa in the elbow decreases friction between the tricep and the underlying bone

subtendinous bursa

500

this joint of the shoulder is often injured due to a blow to the lateral shoulder, even though it is designed to accept axial loading

acromioclavicular joint
