27
Q

roll and slide of humeroulnar and humeroradial joint during flexion

A

Roll and slide: anteriorly

28
Q

roll and slide of humeroulnar and humeroradial joint during extension

A

Roll and Slide: Posteriorly

29
Q

A

Pronation: anterior Spin

31
Q

elbow flexors

A

brachialis
biceps brachii
brachioradialis
pronator teres

32
Q

elbow extensors

A

Triceps
anconeus

33
Q

elbow pronators

A

pronator teres
pronator quadratus

34
Q

elbow supinators

A

biceps brachii
supinator

35
Q

work horse of the elbow flexors; least controversial; uninfluenced by the position of the forearm

active with or without a load; motion is rapid or slow

effective when forearm is pronated

A

Brachialis

36
Q

“supinator longus”

-pure elbow flexor when the forearm is in midposition

A

Brachioradialis

37
Q

three jointed mm (act as shoulder flexor, elbow flexor and forearm supinator)

A

Biceps Brachii

38
Q

biceps brachii is active as elbow flexor when

A

Supinated- with or without load; slow or fast

Pronated- increasing speed and increasing load (greater than 2lbs)

39
Q

biceps brachii little to no activity

A

slow flexion in forearm pronated and 2lbs or
less

40
Q

More powerful, 5x cross section and shortening range 2x than anconeus

  • medial head is next in line after the anconeus “work horse of the elbow extension”

-lateral head- next in line if moderate to high extensor demand

-long head- last to act if high extensors
demand “reserve elbow extensor”

A

Triceps

41
Q

appears to be the fourth head of the extensor mechanism

as to low level of elbow extension, usually first mm to initiate the motion (initiator of elbow extension)

A

Anconeus

42
Q

active during quick elbow supination

A

Biceps Brachii

43
Q

biceps is 4x better as supinator when

A

in 90 deg flexion

44
Q

biceps is 2x better as supinator when

A

elbow is extended

45
Q

active when elbow extended, slow and without resistance

A

Supinator

46
Q

has two heads: humeral and ulnar

-As a primary forearm pronator; strongest

-greatest activity during higher power pronation actions

A

Pronator Teres

47
Q

-pronates the forearm unaided by other mm if pronation is performed slowly without resistance and without active elbow flexion

-is the most active and consistently used pronator muscle, involved during all pronation movements, regardless of the power demands or the amount of associated elbow flexion

-stabilizer of the distal radioulnar joint

A

Pronator Quadratus

48
Q

is the angle formed between the long axis of the upper arm (humerus) and the long axis of the forearm (forearm bones, radius, and ulna) when the elbow is fully extended, and the forearm is supinated (palm facing forward).

A

Carrying angle / Cubital Angle

49
Q

normal values of carrying angle

A

Normal: 15 deg (mean values 5-19 deg)

Men: 11-14 deg

Women: 13-16 deg

50
Q

carrying angles disappears when

A

Full elbow extension with FA pronated

Full elbow flexion with FA supinated

51
Q

increased carrying angle

> 15 deg

A

Cubitus valgus

52
Q

decreased carrying angle, less than 5-15 deg

A

Cubitus varus / Gunstock deformity

53
Q

Mobile Wad of Three

A

Brachioradialis, ECRL, ECR
