vessels

Question 1

principles of the vessels supplying the limbs

Answer 1

• single stem artery
• changes its name according to the region it traverses
• persists to roughly the middle joint where it then divides into 2 branches that continue towards the distal aspect
• distal compartment –> vascular arches –> digital end arteries
• always located on the flexor aspect of the limb

Question 2

what is the single stem artery supplying the upper limb

Answer 2

subclavian artery

Question 3

what is the name changes of the vessels originating from subclavian artery

Answer 3

subclavian –> axillary –> brachial –> radial and ulnar –> digital arteries

Question 4

when does the subclavian artery become the axillary artery

Answer 4

at the outer border of the first rib

Question 5

when does the axillary artery become the brachial artery

Answer 5

at the lower border of teres major where it enters the arm

Question 6

3 parts of the body that the axillary artery supply

Answer 6

anterior chest wall and breast
humerus
anastomoses around the shoulder joint

Question 7

what is enclosed in the axillary sheath

Answer 7

axillary artery, axillary vein and brachial plexus

Question 8

explain the route of the brachial artery

Answer 8

crosses from the medial side towards the elbow. Gets halfway between the lateral and medial epicondyle

Question 9

where does the brachial artery split into the radial and ulnar arteries

Answer 9

at the level of the neck of the radius

Question 10

explain the routes of the radial and ulnar arteries

Answer 10

radial artery slips in under brachioradialis
ulnar artery slips in under FCU with ulnar nerve
both help form the superficial and deep palmar arches

Question 11

what artery supplies the posterior compartment of the upper arm

Answer 11

the brachial artery gives a deep brachial artery/the profunda brachii

Question 12

what structure runs with the profunda brachii artery

Answer 12

the radial nerve

Question 13

what is endangered with fracture of the shaft of the humerus

Answer 13

both the radial nerve and the profunda brachii artery

Question 14

what artery supplies the posterior compartment of the forearm

Answer 14

branch of the ulnary artery –> common interosseous artery –> anterior and posterior intraosseous arteries that run down the front and the back of the intraosseous membrane

Question 15

route of the radial nerve and radial artery when they get to the hand

Answer 15

win onto the back of the dorsum of the hand

• artery goes beneath the tendons of the anatomical snuff box
• radial nerve forms part of the roof (just beneath the skin)

Question 16

explain the branching of the digital arteries

Answer 16

ulnar arteries give rise to common digital arteries –> and then branch again to proper digital arteries

Question 17

where do the veins of the forearm originate

Answer 17

commense at the doral venous arch in the superficial tissues in the back of the hand

Question 18

2 main veins that drain the forearm

Answer 18

cephalic (lateral) vein

basilic (medial) vein

Question 19

what is the communication between the cephalic vein and the basilic vein at the elbow joint

Answer 19

median cubital vein

Question 20

all of the lymph from the upper limb ends up in the

Answer 20

axillary lymph nodes
