A male breast. The human areola (areola mammae, / ə ˈ r iː ə l ə / [1] [2] or / ˌ ær i ˈ oʊ l ə / [2] [3]) is the pigmented area on the breast around the nipple.More generally, an areola is a small circular area on the body with a different histology from the surrounding tissue, or other small circular areas such as an inflamed region of skin.
Furthermore, areolar tissue is the same as loose connective tissue, adipose tissue is a subset of specialized connective tissue, and reticular tissue is the presence of reticular fibers and reticular cells together forming the stroma of hemopoietic tissue (specifically the red bone marrow) and lymphatic tissue organs (lymph nodes and spleen but ...
Lactiferous ducts are ducts that converge and form a branched system connecting the nipple to the lobules of the mammary gland.When lactogenesis occurs, under the influence of hormones, the milk is moved to the nipple by the action of smooth muscle contractions along the ductal system to the tip of the nipple.
The 2.0–4.5 mm milk ducts are immediately surrounded with dense connective tissue that support the glands. Milk exits the breast through the nipple, which is surrounded by a pigmented area of skin called the areola. The size of the areola can vary widely among women. The areola contains modified sweat glands known as Montgomery's glands.
The legality around the exposure of nipples is inconsistently regulated throughout the US. Some states do not allow the visualization of any part of the breast. Other jurisdictions prohibit any female chest anatomy by banning anatomical structures that lie below the top of the areola or nipple. Such is the case in West Virginia and Massachusetts.
Areolar glands, especially during pregnancy and lactation, emit odors that reliably cause newborn babies to face the breast and locate the nipple. Cleaning the breast or otherwise masking these scents makes it harder for newborns to find the nipple, and to get an important first drink of immunoprotective colostrum .
The dermis is the underlying connective tissue layer that supports the epidermis. It is composed of dense irregular connective tissue and areolar connective tissue such as a collagen with elastin arranged in a diffusely bundled and woven pattern. The dermis has two layers: the papillary dermis and the reticular layer.
The lamina propria is a thin layer of loose (areolar) connective tissue, which lies beneath the epithelium, and together with the epithelium and basement membrane constitutes the mucosa. As its Latin name indicates, it is a characteristic component of the mucosa, or the mucosa's "own special layer."
