neurovasculature of the upper limb Flashcards
Name the branches of the arteries in the upper limb (in order)
Subclavian artery
Axillary artery
Brachial artery
Radial artery
Ulnar artery
Where does the subclavian artery originate from in the left and right arm
Left-arch of aorta
Right-brachiocephalic trunk
When does the subclavian artery become the axilla
lateral border of the first rib
What is formed around the surgical neck of the humerous and is prone to damage during a fracture?
Anterior and posterior circumflex humeral arteries
When does the axilla become the brachial artery?
Lower border of the teres major muscle,
Name an important branch of the brachial artery. What does it travel with and through where? What does it supply?
Profunda brachii
Travels with radial nerve- Through radial groove of humerous
Supplies structures in posterior aspect of the arm
Where will you find the brachial pulse?
Medial to the distal tendon of biceps brachii. In the cubital fossa
When does the brachial artery form the Radial and Ulnar arteries?
At the cubital fossa underneath bicipital aponeurosis
What does the ulnar artery give rise to? What does this supply?
Gives rise to the anterior and posterior interosseous arteries, which supply deeper structures in the forearm.
What does the ulnar and radial artery produce in the hand?
Deep and superficial palmer arch
Which artery- radial or ulnar contributes the most to each palmer arch?
Ulnar- deep
Radial- superficial
Where are the radial and ulnar pulses located?
Radial- Lateral to tendon of felxor carpi radialis
Ulnar- Lateral to tendon of flexor carpi ulnaris
Which pulse out of the ulnar and radial, is easier to palpate and why?
Radial pulse is easier
Ulnar pulse runs deeper and lies under pisiform bone
Where else can you palpate the radial pulse?
Anatomical snuff box
What are collateral arteries? Name the 4 in the arm
They are found around joints to allow continuouse supply of blood during movments at the joint.
- Anterior and posterior circumflex arteries
- superior ulnar collateral artery
- Inferior ulnar collateral artery
- Radial collateral artery
Name the superficial veins?
Which is more medial and which is more lateral?
Where are they located?
Basilic- Medial
cephalic - Lateral
Median antecubital- connects across anterior of cubital fossa
Located in the superficial fascia
Name the deep veins
Which compartment are they located in?
Deep veins take the name of accompanying arteries
Subclavian artery and vein
Axillary artery and vein
Brachial artery and vein
Radial artery and vein
Ulnar artery and vein
Located in the deep fascia (muscular compartments)
