Anatomy

Breast are specialized accessory glands of the skin that are capable of secreting milk. Each Breast consists of 15-20 lobes, which radiate out from the nipple. The main duct from each lobe opens separately on the summit of the nipple and possess a dilated ampulla just prior to its termination. Breast is supplied by perforating branches of the internal thoracic artery and the intercostal arteries. The Lymph Drainage of the mammary gland is of considerable clinical importance because of the frequent development of the cancer in the gland and the subsequent dissemination of the malignant cells along the lymph vessels to the lymph nodes. The nerves are derived from the anterior and lateral cutaneous branches of the fourth, fifth, and sixth thoracic nerves.

Abdominal Muscles consist of three broad thin sheet that are aponeurotic in front: they are external oblique, internal oblique , transverses. Blood Supply comprises mainly of Superior Epigastric Artery ,Inferior Epigastric Artery, Deep Circumflex iliac Artery-Lower lateral part of the abdominal wall, Posterior intercostal Arteries-Lateral part of the abdominal wall. The cutaneous lymph drainage above the level of umbilicus drain upward into the anterior axillary lymph nodes. The vessels below this level drain downward into superficial inguinal nodes.

Buttocks region is largely made up of gluteal muscles and a thick layer of superficial fascia. The superior and inferior gluteal arteries supply the gluteal muscle. The lymphatic vessels of the lower extremity consist of two sets, superficial and deep, and in their distribution correspond closely with the veins. 

Thigh is divided into three compartments, each having muscles, nerves and arteries. The compartments are front , inner and lateral thigh. Profunda femoris artery is a large artery that arises from the lateral side of the femoral artery in the femoral triangle. Obturator nerve arises from the Lumbar Plexus (L2,3,4) and arises in the medial border of the psoas muscle within the abdomen. Lymph from the skin and superficial fascia on the back of the thigh drains upward and forward into the vertical group of superficial inguinal lymph nodes.
