Lecture 19 - Thigh Flashcards
2 fascial layers of the thigh
- superficial fatty layer
- deep membranous layer
The 2 fascial layer of the thigh are superficial to what?
fascia latae
deep fascia of the thigh
fascia latae
cutaneous nerves of the thigh
- ilioinguinal nerve
- genitofemoral nerve
- medial cutaneous nerve
- intermediate/anterior cutaneous nerve
- lateral femoral cutaneous nerve
- superficial/anterior branch of obturator nerve
- posterior cutaneous nerve
nerve from L1
ilioinguinal nerve
nerve from L1-2
genitofemoral nerve
nerve from L2-3
lateral femoral cutaneous nerve
cutaneous branches of femoral nerve
- genitofemoral nerve
- medial cutaneous nerve
- intermediate cutaneous nerve
ilioinguinal nerve
- L1
- supplies small area of skin below medial end of inguinal ligament
genitofemoral nerve
- L1-2
- lateral to femoral artery and pierces the sheath and fascia latae
- femoral branch enters femoral sheath
- supplies skin over femoral triangle
medial cutaneous nerve of thigh
- branch of femoral nerve
- supplies skin on medial side of thigh
intermediate cutaneous nerve of thigh
- also called anterior cutaneous nerve
- branch of femoral nerve
- supplies skin on front of thigh down to knee
lateral femoral cutaneous nerve of thigh
- L2-L3
- supplies anterolateral and posterolateral surfaces of thigh
superficial/anterior brach of obturator nerve
- supplies medial aspect of thigh
posterior cutaneous nerve of thigh
- branch of sacral plexus
- supplies posterior aspect of thigh
What represents an area of skin supplied by a specific spinal nerve, regardless of the cutaneous nerves distributed to the same area?
dermatome
Why are dermatomes important?
Can be tested for touch and temperature and are related to specific spinal cord levels
2 superficial veins of lower limb
- great saphenous vein
2. small/lesser saphenous vein
The ____ _______ vein drains the _____ venous arch, passes _____ to the medial _______, runs on the ______ side of the leg and then _______ to the medial _______ of the tibia and femur, ends on the _____ aspect of the thigh in the _______ vein after passing through the _______ _____ in the deep fascia.
The GREAT SAPHENOUS vein drains the DORSAL venous arch, passes ANTERIOR to the medial MALLEOLUS, runs on the MEDIAL side of the leg and then POSTERIOR to the medial CONDYLES of the tibia and femur, ends on the MEDIAL aspect of the thigh in the FEMORAL vein (after passing through the SAPHENOUS HIATUS in the deep fascia.
The _____ _______ vein begins ______ to the lateral malleolus (a continuation of the _____ _______ vein of the foot) and runs along the _____-_______ and reaches the _____ of the leg where it perforates the _____ fascia (at the _____ base) to drain into the ______ ______.
The SMALL/LESSER SAPHENOUS vein begins POSTERIOR to the lateral malleolus (a continuation of the LATERAL MARGINAL vein of the foot) and runs along the TENDO-CALCANEUS and reaches the MIDDLE of the leg where it perforates the DEEP fascia (at the POPLITEAL base) to drain into the POPLITEAL VEIN.
nodes located in upper part of femoral triangle
superficial inguinal nodes
nodes that lie on the medial side of the femoral vein
deep inguinal nodes
