Study Notes
Lower Limb Regions
- The lower limb consists of six regions or parts: Gluteal region, Femoral region (Thigh), Knee joint, Leg region, Ankle joint, and Foot.
Thigh Compartments
- The thigh is divided into three compartments by intermuscular septa:
- Anterior compartment (extensor)
- Posterior compartment (flexor)
- Medial compartment (adductor)
Anterior Thigh Compartment Muscles
- Hip flexors: Quadriceps femoris, Sartorius, Psoas major, and Iliacus
- Blood vessels: Femoral vessels and Great saphenous vein
- Nerves: Femoral nerve
Anterior Thigh Compartment Structures
- Femoral Triangle
- Femoral Sheath
- Adductor Canal
Quadriceps femoris
- Consist of four muscles:
- Rectus femoris
- Vastus medialis
- Vastus intermedius
- Vastus lateralis
- Nerve supply: Femoral nerve
- Action: Knee extension and hip flexion (rectus femoris)
Sartorius Muscle
- Oblique muscle
- Nerve supply: Femoral nerve
- Action: Knee flexion, hip flexion, thigh abduction, and lateral rotation
Psoas Major
- Nerve supply: L1-L3 nerves
- Action: Hip flexion, thigh lateral rotation
Iliacus
- Nerve supply: Femoral nerve
- Action: Hip flexion, thigh lateral rotation
Medial Compartment of the Thigh
- Muscles: Adductor longus, brevis, Magnus, Gracilis, Pectineus, and Obturator externus
- Blood supply: Deep artery of the thigh and Obturator artery
- Nerve supply: Obturator nerve
Obturator Artery
- A branch of the internal iliac artery
- It enters the medial compartment of the thigh through the obturator canal
- It bifurcates into anterior and posterior branches forming a channel around the obturator membrane.
Obturator Nerve
- Arises from the lumbar plexus
- Enters the thigh through the obturator foramen and divides into anterior and posterior divisions.
Femoral Artery
- Continuation of the external iliac artery.
- It descends vertically through the femoral triangle before passing through the adductor canal, and exiting as the popliteal artery
- Branches: superficial epigastric artery, superficial circumflex iliac artery, superficial external pudendal artery, deep external pudendal artery, and profunda femoris artery.
Deep Artery of Thigh(Profunda femoris artery)
- Largest branch of the femoral artery.
- Supplies the thigh
- Passes between the pectineus and adductor longus, between adductor longus and brevis muscles
- Penetrates the adductor magnus to connect with branches of the popliteal artery behind the knee.
- Branches: Lateral circumflex femoral A, Medial circumflex femoral A, Four Perforating arteries
Femoral Vein
- Major deep vein draining the limb
- Becomes external iliac vein when passing under inguinal ligament and entering abdomen
Great Saphenous Vein
- Originates from dorsal aspect of foot.
- Ascends medial side of the leg, knee, and thigh
- Connects with the femoral vein via the saphenous ring in deep fascia inferior to the inguinal ligament.
