byrjar: cubital fossa
-runs along lateral aspect and related to brachioradialis m
-in distal forearm, lateral to flexor carpi radialis
-leaves forearm, passes under
Abd.pollicis longus og ext. pollicis brevis (anatomical snuff box)
–> extensor pollicis longus, penetrating milli metacarpals 1+2
–> reaches palm of hand
-At palm–> Deep palmar arch
-runs w spf. ramus of Radial nerve
Ulnar A
byrjar: cubital fossa
-In forearm runs milli flexor digitorum spf+profundus
-In distal forearm runs milli flx carpi ulnaris + flx digit. profundus
-leaves forearm, enters palm of hand, SPF to flexor retinaculum!
-At palm–> Superficial palmar arch
-runs w ulnar nerve
radial og ulnar artery
(radial A) (ulnar A)
1) radial recurrent aa + ant+post ulnar recurrent aa
*for elbow joint

Veins of upper limbs
með valves to prevent reflux
-spf veins drain into deep veins via perforating veins
*deep veins:
-acc. Arteries.
-named acc. to corresp. aa (t.d radial A og radial veins
eða brachial A og brachial veins, axillary A og axillary veins)
-Are usually paired, to the level of axillary A
*Spf. veins:
-drain skin og subq tissue
-no acc. arteries
-empty into deep veins
- basilic, cephalic og median cubital vein
