CUTANEOUS NERVES AND VESSELS OF LOWER LIMB

1. CUTANEOUS NERVES AND SUPERFICIAL VEINS OF LOWER LIMB

2. GLUTEAL REGION CUTANEOUS NERVES ARE DERIVED FROM POSTERIOR & ANTERIOR RAMI OF SPINAL NERVES: UPPER MEDIAL QUADRANT -> POSTERIOR RAMI OF THE UPPER 3 LUMBAR NERVES & THE UPPER 3 SACRAL NERVES UPPER LATERAL QUADRANT -> LATERAL BRANCHES OF ILIOHYPOGASTRIC (L1) & 12 TH THORACIC NERVES LOWER LATERAL QUADRANT -> BRANCHES FROM LATERAL CUTANEOUS NERVE OF THIGH (L2 & 3, ANTERIOR RAMI) LOWER MEDIAL QUADRANT -> BRANCHES OF POSTERIOR CUTANEOUS NERVE OF THIGH (S1, 2 & 3, ANTERIOR RAMI)

3. FRONT & MEDIAL ASPECT OF THIGH CUTANEOUS NERVES: LATERAL CUTANEOUS NERVE OF THIGH BRANCH OF LUMBAR PLEXUS (L2 & 3) SUPPLIES SKIN OF: LATERAL ASPECT OF THIGH AND KNEE LOWER LATERAL QUADRANT OF THE BUTTOCK FEMORAL BRANCH OF GENITOFEMORAL NERVE BRANCH OF LUMBAR PLEXUS (L1 & 2) SUPPLIES A SMALL AREA OF SKIN THE GENITAL BRANCH SUPPLIES THE SKIN OF CREMASTER MUSCLE ILIOINGUINAL NERVE BRANCH OF LUMBAR PLEXUS (L1) SUPPLIES THE SKIN BEOW MEDIAL PART OF INGUINAL LIGAMENT MEDIAL CUTANEOUS NERVE OF THIGH BRANCH OF FEMORAL NERVE SUPPLIES SKIN OF MEDIAL ASPECT OF THIGH JOINS THE PATELLAR PLEXUS INTERMEDIATE CUTANEOUS NERVE OF THIGH BRANCH OF FEMORAL NERVE SUPPLIES SKIN OF ANTERIOR ASPECT OF THIGH JOINS THE PATELLAR PLEXUS BRANCHES FROM ANTERIOR DIVISION OF OBTURATOR NERVE SUPPLY SKIN ON MEDIAL ASPECT OF THIGH PATELLAR PLEXUS

4. BACK OF THIGH CUTANEOUS NERVES : POSTERIOR CUTANEOUS NERVE OF THIGH

5. FRONT OF LEG SKIN: CUTANEOUS NERVES: LATERAL CUTANEOUS NERVE OF CALF : BRANCH OF COMMON PERONEAL NERVE SUPPLIES SKIN ON UPPER PART OF LATERAL SURFACE OF THE LEG SUPERFICIAL PERONEAL NERVE : BRANCH OF COMMON PERONEAL NERVE SUPPLIES SKIN OF LOWER PART OF ANTEROLATERAL SURFACE OF THE LEG SAPHENOUS NERVE : BRANCH OF FEMORAL NERVE SUPPLIES SKIN OF ANTEROMEDIAL SURFACE OF LEG SUPERFICIAL VEINS: DRAIN INTO GREAT SAPHENOUS VEIN

6. BACK OF LEG CUTANEOUS NERVES : POSTERIOR CUTANEOUS NERVE OF THIGH SUPPLIES SKIN OVER THE POPLITEAL FOSSA & UPPER PART OF BACK OF LEG LATERAL CUTANEOUS NERVE OF CALF BRANCH OF COMMOM PERONEAL NERVE SUPPLIES SKIN OF UPPER PART OF POSTEROLATERAL SURFACE OF THE LEG SURAL NERVE BRANCH OF TIBIAL NERVE SUPPLIES SKIN ON THE LOWER PART OF POSTEROLATERAL SURFACE OF THE LEG SAPHENOUS NERVE BRANCH OF FEMORAL NERVE GIVES OFF BRANCHES THAT SUPPLY THE SKIN ON THE POSTEROMEDIAL SURFACE OF THE LEG SUPERFICIAL VEINS: DRAIN INTO SMALL SAPHENOUS VEIN

7. DORSUM OF FOOT SENSORY SUPPLY SUPERFICIAL PERONEAL NERVE- supplies the skin on the dorsum of the foot; the medial side of the big toe; and the adjacent sides of the second, third, fourth and fifth toes. DEEP PERONEAL NERVE- supplies the skin of the adjacent sides of the big and second toes. SAPHENOUS NERVE- supplies the skin along the medial side of the foot as far forward as the head of the first metatarsal bone SURAL NERVE- supplies the skin along the lateral margin of the foot and the lateral side of the little toe MEDIAL AND LATERAL PLANTAR NERVES- nail beds and the skin covering the dorsal surfaces of the terminal phalanges.

8. Dorsal Venous Arch: The dorsal venous arch lies in the subcutaneous tissue over the heads of the metatarsal bones. Drains on the medial side into the great saphenous vein and on the lateral side into the small saphenous vein. The great saphenous vein leaves the dorsum of the foot by ascending into the leg in front of the medial malleolus. The small saphenous vein ascends into the leg behind the lateral malleolus .

10. SOLE OF FOOT SENSORY NERVE SUPPLY : MEDIAL CALCANEAL BRANCH OF THE TIBIAL NERVE -> MEDIAL SIDE OF HEEL BRANCHES FROM MEDIAL PLANTAR NERVE -> MEDIAL 2/3 rd OF SOLE BRANCHES FROM LATERAL PLANTAR NERVE -> LATERAL 1/3 rd OF THE SOLE
