Part I: nerves of the lower limb
Objectives:
By the end of this lab students are expected to be able to identify the following structures:
1. Femoral Nerve
? Deep to inguinal ligament
? Femoral triangle (lateral to femoral artery)
? Divides to branches (Short course)
2. Saphenous nerve (superficial)
? Branch of the femoral nerve at femoral triangle
? Passes through adductor canal
? Medial side of the knee
? Accompany the long saphenous vein down to ankle
? In front of medial malleolus (with great saphenous vein)
3. Obturator Nerve
? Passes through the obturator foramen
? Reach the Adductor compartment
? Divides to anterior and posterior branches (Short course)
4. Sciatic nerve
? Enters the gluteal region by passing through greater sciatic foramen
? Enters the posterior thigh by passing just lateral to the ischial tuberosity
? Divide near the popliteal fossa into tibial and common peroneal
5. Tibial nerve
? Medial terminal branch of the sciatic nerve in popliteal fossa
? Pass deeply between the two heads of gastrocnemius deep to soleus
? Pass behind medial malleolus (with posterior tibial artery)
? Reach the sole of the foot
6. Sural nerve (superficial)
? Branch of tibial nerve
? Emerge between the two heads of gastrocnemius
? Take a superficial course at the Back of the leg (with short saphenous vein)
? Pass behind the lateral malleolus (superficial)
7. Common peroneal nerve
? Lateral terminal branch of the sciatic nerve in the popliteal fossa
? Across the lateral head of the gastrocnemius
? Subcutaneous just distal to the head of the fibula
8. Superficial peroneal nerve
? Lateral compartment of the leg
? Becomes subcutaneous near the middle of the leg
? Pass superficial to extensor retinacula
9. Deep peroneal nerve
? Anterior compartment of the leg (with anterior tibial artery)
? Deep to the extensor retinacula

Part II: vessels of the lower limb
Objectives:
By the end of this lab students are expected to be able to identify the following structures:
1. Femoral artery
? Deep to inguinal ligament
? Midway between ASIS and pubic tubercle
? Femoral triangle (lateral to femoral vein)
? Adductor canal and hiatus
? Continue as popliteal artery
2. Profunda femoris artery
? Branch of femoral artery (from lateral side)
? Pass medially behind the artery
? Pass deep to adductor longus
3. Popliteal artery
? Continuation of femoral artery
? From adductor hiatus to soleus
? Deep to all other neurovascular structures passing through the popliteal fossa
? Divides into anterior and posterior tibial arteries
4. Anterior tibial artery
? Terminal Branch of popliteal artery
? Pass along the anterior compartment of leg (with deep peroneal nerve)
? Pass deep to extensor retinacula
? Continue as dorsalis pedis artery.
5. Dorsalis pedis artery
? Direct continuation of the anterior tibial artery
? Pass along the dorsum of the foot
? Just lateral to extensor hallucis longus tendon (here it can be palpated)
6. Posterior tibial artery
? Terminal Branch of popliteal artery
? Pass along the posterior compartment of leg (with tibial nerve)
? Pass behind medial malleolus where it can be palpated
? Enter the sole of the foot
