Kines Exam 2- Elbow And Radioulnar Joints

Front 1

elbow and radioulnar joints

Back 1

most UE movements involve the E and RU joints
contribute with SG and SJ to the versatility and precision of the UE
impairment at any of the UE joints causes significant reductions in the usefulness of the hands and fingers

Front 2

elbow joint structure

Back 2

humeroulnar: hinge joint
humeroradial: gliding joint

Front 3

radioulnar joints (proximal and distal)

Back 3

pivot joints: between the proximal radius and the radial notch of the Ulna
-between the distal radius and ulna

Front 4

carrying angle

Back 4

slightly abduction of the FA relative to the UA in the anatomical position

larger in females

carrying angle disappears as elbows is flexed and/or pronated

Front 5

ANTERIOR: biceps brachii

Back 5

two heads: long head- origin supraglenoid tubercle on the superior edge of the glenoid fossa of the scapula
short head: origin- coracoid process of the scapula
insertion: radial tuberosity

Front 6

muscle of elbow and radioulnar joint

Back 6

anterior: FLEXION (elbow region) biceps brachii, brachialis, brachioradialis, pronator teres

anterior (wrist region) extension: pronator quadratus

posterior EXTENSION: triceps brachii, anconeus, supinator

Front 7

brachialis muscle

Back 7

flexion on the elbow

Front 8

biceps brachii muscle

Back 8

flexion of elbow, supination of forearm, weak flexion of shoulder joint

Front 9

ANTERIOR brachioradialis

Back 9

flexion of elbow, pronation from supinated position to nuetral, supination from pronated position to neutral

origin:distal 2/3 of lateral condyloid
insertion: lateral surface of the distal end of the radius at the styloid process, under BB

Front 10

pronator teres muscle

Back 10

pronation of forearm
weak flexion of elbow

origin: distal part of the medial condyloid ridge of the humerus and medial side of the proximal ulna
insertion: middle 1/3 of the lateral surface of the radius

Front 11

pronator quadratus

Back 11

origin: distal 1/4 of the anterior side of ulna
insertion: distal 1/4 of the anterior side of the radius

pronation of forearm

Front 12

triceps brachii muscle

Back 12

all heads do extension of the elbow

*long head: extension of shoulder joint adduction of shoulder joint (does nothing to radial ulna just elbow)

Front 13

Anconeus muscle

Back 13

extension of elbow.
origin: posterior surface of the lateral condyle of the humerus
insertion: posterior surface of the olecranon process of the ulna

Front 14

POSTERIOR supinator

Back 14

supination of forearm

origin: lateral epicondyle of the humerus and neighboring posterior part of the ulna

insertion: lateral surface of the proximal radius just below the head

Front 15

flexion

Back 15

BB
brachioradialis (most active mid P/S)
pronator teres- most active when pronated
overall, most force mid to supinated FA
