blood vessels of the upper limb Flashcards
where does the axillary artery become the brachial artery
at the inferior boarder of the teres major
what are the branches we need to know from the brachial artery and the axillary artery
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
where does the deep brachial artery run and what is it running along side
it runs through the radial groove on the humerus along side the radial nerve
what is the blood innervation for the anterior arm
brachial artery is the anterior arm compartment
whats the blood innervation for the posterior arm
deep brachial artery
what does the brachial artery divide into
the brachial artery divides intp the ulnar and radial artery
what are the divisions of the ulnar artery and where do they go
ulnar artery divides into the common interosseous artery, which then divides into the anterior and posterior interosseous arteries
the radial and ulnar arteries converge to make what
all the arteries of the hand
what supplies the posterior forearm
the posterior interosseous artery
what supplies the anterior forearm
the radial artery, ulnar artery and the anterior interosseous artery provide blood for the anterior forearm compartment
in general in the hand, the radial artery supplies what and the ulnar artery supplies what
Radial artery mainly supply the thumb and the radial side of the index finger
Remaining digits are from ulnar artery
the superficial palmar arch is mainly supplied by what.
the ulnar artery hence its bigger in size here
where does the superficial palmar arch lie
- Lie superficial to long flexor tendons
what are the branches of the superficial palmar arch and where do they go?
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
where is the deep palmar arch found
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
