Adult Upper Limb Arteries:
- Discussion: Upper Limb Development;
-
subclavian artery projects into the early upper limb bud & forms
subclavian-axillary-brachial
trunk;
- its distal portion becomes interosseous artery that initially supplies
plexus of arteries in the primitive hand;
- branch of trunk artery,
median artery, temporarily replaces interosseous
artery in supplying the hand;
- subsequently,
ulnar and then
radial arteries are formed & supplies
forearm and of
superficial &
deep palmar arches of hand;
-
deep branch of
brachial artery
& arteries about shoulder
& elbow arise relatively late as branches of primary axial vessel;
- Discussion: Lower Limb Development:
- umbilical artery it gives off small branch,
ischiadic artery, that temporarily
serves supplies the growing limb;
- external iliac artery, arising from umbilical artery slightly proximal to
ischiadic,
soon provides most of the blood supply to the limb and goes on to
successively,
femoral , popliteal, &
posterior tibial artery;
- anastomosis is formed as
popliteal artery
passes near
ischiadic,
artery and the lower part of
ischiadic becomes
peroneal
artery;
-
anterior tibial artery is subsequently formed;
- persisting distal portions of
ischiadic artery
become peroneal &
inferior genicular
arteries;
- proximal portion persists as branch of
inferior gluteal artery, which lies
anastomoses w/ lateral &
MFCA
& first
perforating branch of
deep femoral artery;
- anastomosis sometimes called
cruciate or crucial anastomosis;
- early vascular plexus of foot is supplied by
ischiadic artery
- as this connection regresses, plexus is supplied by posterior tibial;
- later, new
anterior tibial artery
reaches foot & comes to supply
dorsal arcuate artery & its branches, &
posterior tibial artery
supplies the plantar arteries.
