Excerpt from Cyclopædia of Obstetrics and Gynecology, Vol. 9: Diseases of the Female Mammary Glands and New Growths of the Uterus The arteries of the mammary glands are chie¿y given Off from the in ternal mammary and long thoracic arteries, the branches of these arteries anastomose to a considerable extent, and are much enlarged during the activity of the gland. They spread out into finer and finer twigs, until they form a capillary net-work surrounding the single lobules. From these capillary net-works arise numerous venules, which, following the course of the arteries, form dense net-works under the skin, and finally empty into the internal mammary and thoracic vein, many of the sub cutaneous veins emptying into the external jugular (luschka). The mammary glands are very rich in lymphatic plexuses, which are partly situated deep down in the gland, partly subcutaneous. They form tolerably narrow closed plexuses, not communicating with the connective tissue interspaces (langhaus), which surround the lobules of the glands near the capillary plexuses and accompany the excretory duct. They arise from club-like processes in the papillae of the mammary areola (as in the skin), form cutaneous and subcutaneous plexuses, and then unite to form lymphatic trunks. The superficial as well as the deep lymphatic trunks pass for the most part to the lymphatic glands of the axillary space, where they unite with the lymphatic vessels of the intercostal spaces and through these with those Of the thoracic cavity.
