A

Interosseus palmaris nerve (part of median nerve from C8-T1)

33
Q

True or false: the median nerve innervates the five muscles originating from the medial epicondyle

A

TRUE

34
Q

Which muscles originate from the medial epicondyle? (5)

A

1) pronator teres
2) flexor carpi radialis
3) flexor carpi ulnaris
4) flexor digitorum superficialis
5) palmaris longus

35

Ulnar nerve

36
Q

Which nerve supplies all the extensor muscles in the arm and forearm?

A

Radial nerve

37
Q

Which nerve is damaged in a humeral fracture?

A

Radial nerve - all muscles innervated by this nerve lose function

38
Q

2) flexor pollicis longus
3) pronator quadratus

39
Q

Name the extensor muscles of the wrist and fingers (4)

A

1) extensor carpi radialis longus
2) extensor carpi radialis brevis
3) extensor carpi ulnaris
4) extensor digitorum communis

40
Q

2) flexor carpi ulnaris
3) palmaris longus
4) superficial flexor digitorum
5) flexor pollicis longus

41
Q

Which nerve innervates the extensor muscles of the wrist and fingers?

A

Radial nerve

42
Q

Which nerve innervates all the flexor muscles of the wrist and fingers, except for flexor carpi ulnaris?

A

Median nerve (flexor carpi ulnaris is innervated by ulnar nerve)

43
Q

What is compartment syndrome?

A

When there is a fracture in fascial compartments, it leads to bleeding in these compartments and the arteries collapse. This increases the pressure and the blood supply to the muscle is cut off so the muscle undergoes necrosis

44
Q

What is an olecranon bursa?

A

Sac fills with fluid when it becomes inflamed

45
Q

Which mnemonic is used to remember the carpal bones?

A

She Looks Too Pretty

Try To Catch Her

Q

Name the carpal bones (8)

Scaphoid
Lunate
Triquetral
Pisiform

Trapezium
Trapezoid
Capitate
Hamate

47
Q

What makes up the three borders of the cubital fossa?

A

Lateral border-brachioradialis muscle
Medial border-pronator teres muscle
Superior border-imaginary line between epicondyles of humerus

48
Q

Which tendon runs through the cubital fossa?

A

Biceps tendon

49
Q

Which artery runs through the cubital fossa and what does it bifurcate into at the apex?

A

Brachial artery

Into radial and ulnar arteries

50
Q

Which nerve runs through the cubital fossa?

A

Median nerve
