L7.2 - Vessels of UL Flashcards
What can be found around major joints?
Anastomosis
Where is the axillary vein located in terms to axillary artery?
Medial
Axillary artery divides into 3 parts
Above, beneath and below pec. minor
RaBAM at cubittal fossa
Going lateral to medial:
- Radial Nerve
- Biceps tendon
- Artery, Brachial
- Median Nerve
Brachial artery - how it descends
Starts off medial but ends up in between CEO and CFO as it descends to forearm
BS for triceps
Profunda brachii that winds around to back of arm to supply tricpes.
*Accompanied by radial nerve posteriorly
Radial artery - what does it run under?
Joins superficial branch of radial nerve and runs under brachioradialis
Radial artery - how does it travel to palmar aspect of the hand? Where does the radial nerve want to travel to, dorsal or palmar?
Goes through snuffbox, over the floor and pierces 1st dorsal interosseous
Radial nerve - dorsal
Ulnar artery - what does it run under?
FCU, along with ulnar nerve. Going over the top of the flexor retinaculum and into the palm
What branch does the ulnar artery give off?
After its origin, it gives off a common interosseous artery which divides into ant and post, running front and back, respectively, supplying deep muscles of the forearm
What artery forms the superficial palmar arch? Deep? What structures do they supply?
Superficial - ulnar a (placed at level of distal border of outstretched thumb, supplies medial 3 1/2 fingers)
Deep - radial a (more proximally paced and supplies 1 1/2 lateral fingers, has MC branches)
Always 2 types of veins - what are they?
Superficial - always visible
Deep - accompanies arteries
*Free anastomosis between the 2 and valves present to ensure unidirectional flow
Dorsal venous arch
The dorsal venous network of the hand is a network of veins formed by the dorsal metacarpal veins.
-It is where the bulk of venous blood from palm is, driven by the pressure of gripping
Cephalic vein in deltopectroal groove pierces the clavipectoral fascia and joins the axillary vein
Basilic vein goes halfway up the arm to lower border of teres major and piece deep fascia to join brachial vein to form axillary vein
Cephalic vein in deltopectroal groove pierces the clavipectoral fascia and joins the axillary vein
Basilic vein goes halfway up the arm to lower border of teres major and piece deep fascia to join brachial vein to form axillary vein
Which lymph node does all of UL drain into?
Axillary lymph nodes
