Study Notes
Cutaneous Nerves of the Thigh
- Ilioinguinal nerve originates from L1
- Femoral branch of genitofemoral nerve originates from L1-2
- Lateral cutaneous nerve of the thigh originates from L2-3
- Intermediate cutaneous nerve of the thigh originates from L2-3
- Medial cutaneous nerve of the thigh originates from L2-3
- Saphenous nerve originates from L3-4
- Cutaneous branch from the anterior division of the obturator nerve originates from L3-4
Cutaneous Vessels of the Thigh
- Lateral vessels of the thigh
- Obturator vessels of the thigh
- Intermediate vessels of the thigh
- Upper part of great saphenous vein
Superficial Inguinal Lymph Nodes
- Located in the superficial fascia of the thigh (Fig.A85)
Deep Fascia (Fascia Lata) of the Thigh
- Fibrous tough sheath that surrounds the thigh like a stocking, except for the saphenous opening
- Thinned out medially to form the cribriform fascia
- Thickened laterally to form the iliotibial tract
- Superior attachments:
- Medially: pubic arch, ischial tuberosity, and sacrotuberous ligament
- Anteriorly: inguinal ligament and superior pubic ramus
- Laterally: iliac crest
- Posteriorly: sacrum and coccyx
- Inferior attachments:
- Condyles of the femur and tibia
- Patella and head of fibula
- Thick popliteal fascia posteriorly
