blood vessels of the upper limb

Question 1

where does the axillary artery become the brachial artery

Answer 1

at the inferior boarder of the teres major

Question 2

what are the branches we need to know from the brachial artery and the axillary artery

Answer 2

brachial artery gives rise to the deep brachial artery. axiallry artery gives rise to the anterior and posterior circumflex humeral arteries which run around the surgical neck of the humerus

Question 3

where does the deep brachial artery run and what is it running along side

Answer 3

it runs through the radial groove on the humerus along side the radial nerve

Question 4

what is the blood innervation for the anterior arm

Answer 4

brachial artery is the anterior arm compartment

Question 5

whats the blood innervation for the posterior arm

Answer 5

deep brachial artery

Question 6

what does the brachial artery divide into

Answer 6

the brachial artery divides intp the ulnar and radial artery

Question 7

what are the divisions of the ulnar artery and where do they go

Answer 7

ulnar artery divides into the common interosseous artery, which then divides into the anterior and posterior interosseous arteries

Question 8

the radial and ulnar arteries converge to make what

Answer 8

all the arteries of the hand

Question 9

what supplies the posterior forearm

Answer 9

the posterior interosseous artery

Question 10

what supplies the anterior forearm

Answer 10

the radial artery, ulnar artery and the anterior interosseous artery provide blood for the anterior forearm compartment

Question 11

in general in the hand, the radial artery supplies what and the ulnar artery supplies what

Answer 11

Radial artery mainly supply the thumb and the radial side of the index finger
Remaining digits are from ulnar artery

Question 12

the superficial palmar arch is mainly supplied by what.

Answer 12

the ulnar artery hence its bigger in size here

Question 13

where does the superficial palmar arch lie

Answer 13

• Lie superficial to long flexor tendons

Question 14

what are the branches of the superficial palmar arch and where do they go?

Answer 14

the common palmar digital arrtery and the proper palmar digital artery.
the common palmar digital arteries divide aty the fingers to innervate either side of each finger - these division are the proper palmar digital arteries

Question 15

where is the deep palmar arch found

Answer 15

the radial artery passes over the floor of the anatomical sniff box to the palmar side of the hand, but it joins the deep ulnar artery so that is can lie on the metacarpal bones and the interosseous muscles

Question 16

what are the branches of the deep palmar arch

Answer 16

the palmar metacarpal arterues, princeps pollicis artery and the radial indicis artery.

Question 17

what are the two superficial veins that stem from the veins of the upper limb

Answer 17

laterally the cephalic vein and the basilic vein medially

Question 18

where doe the cephalic and basilic veins drain into

Answer 18

the cephalic into the axillary vein and the basilic into the brachial vein

Question 19

what connects the cephalic and basilic veins and where is it found

Answer 19

connected by the median cubital vein which passes over the cubital
