31
Q

What two arteries does the Brachial artery slip into in the cubital fossa?

A

Radial and Ulnar arteries

32
Q

Where is the Brachial artery in the level of the elbow and why is it clinically important?

A

at the level of the elbow Brachial artery is anterior aspect after piercing through the cubital fossa. This location is where to take BP.

33
Q

A

very superficial especially near the wrist

36
Q

What does the Radial artery travel just lateral to in the wrist?

A

distal flexor carpi radialis tendon

37
Q

what is the clinical importance of the distal flexor carpi radialis tendon?

A

Pulse point

38
Q

what does the radial artery travel into posteriorly after the distal flexor carpi radialis tendon?

A

anatomical snuff box

39
Q

what does the anatomical snuff box sit directly superficial to?

A

scaphoid bone

40
Q

The snuff box is found by three tendons what are they?

A

Lateral aspect: extensor pollicis brevis and abductor pollicis longus
Medial aspect: extensor pollicis longus
Floor aspect: most proximal and lateral carpal bone: scaphoid

41
Q

does scaphoid bone have good blood supply?

A

No. The posterior is very avascular.

42
Q

which carpal bone fractures the most often?

A

the scaphoid bone

43
Q

If someone comes and complains about falling and wrist pain, which bone do you palpate?

A

the scaphoid bone

44
Q

After the Radial artery traveled through the anatomical snuff box it will dive back anteriorly toward the palm side and do what?

45
Q

what is the distal palmar split of the radial artery?

A

Splits into superficial palmar arch and deep palmar arch

46
Q

what does superficial palmar arch and deep palmar arch come together to form?

A

anastomosis

47
Q

The Ulnar artery travels deep to what?

A

Flexor carpi ulnaris

48
Q

what nerve runs along side of the ulnar artery deep to flexor carpi ulnaris?

A

Ulnar nerve

49
Q

What aspect of the forearm is the Ulnar artery and ulnar nerve running?

50
Q

As soon as the Ulnar artery branches from the brachial artery what does it give off?

A

the common interosseous artery

51
Q

The common interosseous artery branches into what two arteries?

A

posterior and anterior interosseous arteries

52
Q

what nerves travel along the posterior and anterior interosseous artery?

A

posterior and anterior interosseous nerve

Q

What does the Ulnar artery travel into the hand through?

A

Guyon’s canal

Q

what artery does the Ulnar artery anastomose with in the hand?

A

radial artery

Q

What test is to test the purfusion of the hand testing the ulnar and radial artery?

A

Alan’s test

58
Q

How is the subclavian vein found in the origin region? HINT: what muscle is it oriented to?

A

Anterior to the anterior scalene

59
Q

What bone is the subclavian vein level to?

60
Q

What vein does the subclavian vein become once it passes the level of the clavicle?

A

Axillary vein

61
Q

What vein is the most medial in the axillary fossa?

A

Axillary vein

62
Q

What would the axillary vein look like?

A

Brachial vein

65
Q

What does the brachial vein branch into in the arm area?

A

Smaller veins that surround the Ulnar and radial arteries. they are called Cephalic vein and Basilic vein.

66
Q

Superficial venous Cephalic vein travels how on the arm?

67

68
Q

What does the Cephalic vein travel through?

A

Delto-pectoral groove

69
Q

Where does the Cephalic and Basilic veins join at ?
