Mammary Gland Lobules

Last updated: Jul 31st, 2024

The mammary gland lobules, or mammary gland lobes, are located within the female breast. There are fifteen to twenty irregularly shaped lobes, each of which includes alveolar glands, and a duct (lactiferous duct) that leads to the nipple and opens to the outside. The lobes are separated by dense connective tissues that support the glands and attach them to the tissues on the underlying pectoral muscles.
