Description
The lower limb is made up of six regions: the gluteal, femoral (or thigh), knee, leg, talocrural (or ankle), and foot regions.
Arterial supply to the gluteal region arises directly or indirectly from the internal iliac artery, while the principal blood supply to the remaining lower limb is via the external iliac and femoral arteries. The inguinal region acts as a transitional zone, providing a passageway for vessels and nerves to pass between the abdominal cavity and lower limb.
The obturator canal is a small opening in the obturator membrane that acts as a passage for the obturator vessels and nerve to travel between the pelvis and femoral region.
The gluteal region communicates with the lower limb and abdominopelvic cavity via the greater and lesser sciatic foramina, respectively.
