33
Q

What is the origin and insertion of flexor carpi ulnaris?

A

Origin is at the medial epicondyle and the posterior ulna. Insertion is at the pisiform, hamate, and base of 5th metacarpal

34
Q

identify the route of the radial nerve as it relates to the cubital fossa

A

Radial nerve: Adjacent to cubital fossa, it branches to the superficial radial nerve (between brachioradialis and extensor carpi radialis longus) and the deep branch (posterior interosseous nerve) which pierces the supinator

35
Q

Identify the route of the ulnar nerve as it relates to the cubital fossa

A

Adjacent to the cubital fossa, the ulnar nerve enters the forearm between the two heads of the flexor carpi ulnaris and is found between the flexor carpi ulnaris and the flexor digitorum profundus

Near the hand, the ulnar nerve breaks into the dorsal branch and palmar branch

36
Q

What are the contents of the cubital fossa?

A

TAN

Bicep brachii tendon

Brachial artery

Median nerve

37
Q

What nerve supplies the palmaris longus, flexor carpi radialis, pronator teres, and flexor digitorum superficialis?

A

Median nerve

38
Q

What nerve supplies flexor carpi ulnaris?

A

Ulnar nerve

39
Q

What is the origin and insertion of flexor digitorum superficialis?

A

Origin is at the medial epicondyle of the humerus, coronoid process of ulna and the oblique line of the radius

Insertion is at the middle phalanges of the 2-5 fingers

40
Q

What is the origin and insertion of flexor digitorum profundus?

A

Origin is at the medial surface of the ulna and insertion is at the base of the distal phalanges of fingers 2-5

Q

What nerve supplies the flexor digitorum profunda?

A

The medial half is supplied by the ulnar nerve and the lateral half is supplied by the medial nerve.

42
Q

What is the origin and insertion of the flexor pollicus longus?

A

Origin is at the anterior radius and the insertion is at the base of the distal phalynx of the thumb

43
Q

What is the origin and insertion of the pronator quadratus?

A

Origin is at the distal anterior ulna and insertion is at the distal anterior radius

44
Q

What nerve supplies the flexor pollicis longus and pronator quadratus?

A

median nerve (anterior interosseous nerve)

45
Q

After leaving the cubital fossa, the brachial artery branches to the radial and ulnar arteries. The radial artery continues distally along with which nerve?

A

The superficial radial nerve along the brachioradialis

46
Q

After leaving the cubital fossa, the brachial artery branches to the radial and ulnar arteries. The ulnar artery then supplies the common interosseous artery. The ulnar artery then travels distally to meet what nerve?

A

The ulnar artery travels with the median nerve through the two heads of the flexor digitorum superficialis then medially to meet the ulnar nerve

47
Q

What is the course of the median nerve as it passes through the cubital fossa?

A

At the apex of the cubital fossa, the median nerve supplies the branch of the anterior interosseous nerve then it passes through the 2 heads of the pronator teres. Distally it continues through the 2 heads of the flexor digitorum superficialis (running with the ulnar artery)

48
Q

What is the origin and insertion of the supinator?

A

The origins are at the lateral epicondyle and the supinator crest of the ulna The insertion is at the proximal radius (Brings the radius back to the posterior ulna)
