Superior boundary of the gluteal region
iliac crest
medial boundary of gluteal region
intergluteal cleft
inferior boundary of gluteal region
gluteal fold
Anterior compartment at the thigh: innervation and action
flexes the thigh and extends the knee joint
innervated by the femoral nerve
Posterior compartment of the the thigh: innervation and action
extends the thigh and flexes the knee
innervated by the tibial nerve (Branch of the sciatic nerve)
Medial compartment of the thigh
innervation and action
adducts the thigh at the hip joint
innervation is the obturator nerve
iliac muscle
(O)- iliac fossa
(I)- lesser trochanter
(N)- femoral nerve
(A)- flex the the thigh at the hip
Psoas muscle:
(O)- T12 - L5
(I)- the lesser trochanter
(N)- Femoral nerve
(A) - flex thigh at the hip

The Femoral triangle
a junctional region between the trunk and
lower limb.
▪ It is a triangular fascial space in the superoanterior third of the
thigh.
FEMORAL TRIANGLE- CONTENT
▪ Femoral nerve and its branches
▪ Femoral sheath and its contents
▪ Femoral artery and its branches
▪ Femoral vein and its proximal tributaries
(great saphenous and deep femoral
veins)
