Upper Limb 3 Flashcards
What are the muscles of anterior compartment of the forearm (superficial, middle, deep, oddity)?
- pronator teres
- flexor carpi radialis
- palmaris longus
- flexor carpi ulnaris
- flexor digitorum superficialis
- flexor digitorum profundus
- flexor pollicis longus
- pronator quadratus
- brachioradialis
What is the origin, insertion, action, innervation of the pronator teres?
O: medial epicondyle of humerus
I: lateral surface of radius
A: pronation, flexion
IN: median nerve
What is the origin, insertion, action, innervation of the flexor carpi radialis?
O: medial epicondyle of humerus
I: 2nd metacarpal
A: flexion, abduction
IN: median nerve
What is the origin, insertion, action, innervation of the palmaris longus?
O: medial epicondyle of humerus
I: flexor retinaculum, aponeurosis
A: tightens palmar aponeurosis
IN: median nerve
What is the origin, insertion, action, innervation of the flexor carpi ulnaris?
O: medial epicondyle of humerus
I: pisiform, hamate, 5th metacarpal
A: flexion, adduction
IN: ulnar nerve
What is the origin, insertion, action, innervation of the brachioradialis?
O: lateral supracondylar ridge of humerus
I: lateral surface radius
A: flexion
IN: radial nerve
What is the origin, insertion, action, innervation of the flexor digitorum superficialis?
O: medial epicondyle of humerus, ulna
O: ant border of radius
I: middle phalanges 2-5
A: flexion at IP and MP joints
IN: median nerve
What is the origin, insertion, action, innervation of the flexor digitorum profundus?
O: medial/anterior surface of ulna
I: distal phalanges 2-5
A: flexion at distal IP and hand
IN: median nerve (2-3) and ulnar nerve (4-5)
What is the origin, insertion, action, innervation of the flexor pollicis longus?
O: anterior surface of radius
I: distal phalanx of thumb
A: flexion
IN: median nerve
What is the origin, insertion, action, innervation of the pronator quadratus?
O: ulna
I: radius
A: pronation
IN: median nerve
What is golfer’s elbow vs tennis elbow?
inflammation at medial epicondyle (flexion)
inflammation at lateral epicondyle (extension)
What is carpal tunnel syndrome?
flexor retinaculum – flexor tendons and median nerve
- overuse = pressure/compression of median nerve
