1) The muscular branches for the m. piriformis, m. obturatorius internus with mm.gemelli and quadratus femoris;
2) The superior gluteal nerve emerges through the foramen suprapiriforme from pelvis
3) The inferior gluteal nerve emerges through the foramen infrapiriforme
4) The pudendal nurve emerges through the foramen infrapiriforme curving around spina ischiadica, passes back into the pelvis through the foramen ischiadicum minus.
Morpho-functional characteristics of skin covering of the lower limb. Superficial and deep veins of lower extremity, their topography and projections. Lymphatic vessels and nodules of lower limb. Cutaneous nerves of the lower limb, its supply region.
Superficial veins:
-small saphenous vein: The origin of the small saphenous vein, is where the dorsal vein from the fifth digit merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein. It is a superficial vein being subcutaneous, (just under the skin).
-great saphenous vein: The great saphenous vein (GSV), previously also called the long saphenous vein, is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body running along the length of the leg.
The Lymph Glands of the Lower Extremity—The lymph glands of the lower extremity consist of the anterior tibial gland and the popliteal and inguinal glands.
Cutaneous nerves of thigh: Anterior cutaneous branches of the femoral nerve; Cutaneous branch of the obturator nerve; Posterior cutaneous nerve of thigh.
Common fibular nerve (blue) - labeled as "peroneal nerve". Also Lateral sural cutaneous nerve. Saphenous nerve, a branch of the femoral nerve. Superficial fibular nerve - labeled as "superficial peroneal nerve". Also Medial dorsal cutaneous nerve. Sural nerve. Also Medial sural cutaneous nerve.
