WEEK 9/1 > LOWER LIMB VESSELS Flashcards
LYMPHATIC VESSELS OF THE LOWER LIMB
- VESSELS
- NODES
VESSELS
- form a deep and superficial system seperated by the deep fascia
where are the nodes located
- proximally in the limb in the region of the femoral triangle
where are small number of nodes located in
- SOMETIMES in the popliteal fossa
NODES
inguinal lymph nodes are in two groups > superficial and deep
where are the superficial nodes located
- beneath the inguinal ligament and along the proximal part of the long saphenous vein
location of the deep nodes
- medial to the femoral vein in the region of the femoral canal
where do the superficial nodes drain into
drain lymph from the superficial lower limb vessels and also from the perineum, and the superficial lower trunk wall then drain into deep group
where do deep group drain into
- into external illiac nodes which are located in the abdominal cavity
ARTERIES OF THE LOWER LIMB
- superior gluteal artery
- inferior gluteal artery
- obturator artery
- femoral artery
- produnfa femoris artery
- popliteal artery
- anterior tibial artery
-dorsal pedis artery - posterior tibial artery
- plantar arteries
where do the lower limb arteries enter through
- gluteal region, obturator canal or femoral triangle
SUPERIOR GLUTEAL ARTERY
SGA Arises from?
- internal iliac artery in the pelvic cavity
SGA Exits from?
- pelvic cavity via the greater sciatic foramen above the piriformis
SGA ENTERS?
- gluteal region > supplying several structures
INFERIOR GLUTEAL ARTERY
IGA arises from?
- internal illiac artery in the pelvic artery
IGA EXITS FROM
- exits pelvic cavity via the greater sciatic foramen below piriformis
WHAT DOES THE IGA FORM
- anastomosis around the proximal femur
OBTURATOR ARTERY
OA arises from
- internal iliac artery in the pelvic artery
OA exits from
OBTURATOR CANAL
FEMORAL ARTERY
FA ARISES FROM
- renamed continuation of the external iliac artery as it passes beneath the inguinal ligament
