In surgical parlance, the cleavage or intermammary cleft is also known as the "medial definition" or "medial fold" of breasts. [ 15 ] [ 16 ] An imaginary line between the nipples that crosses the intermammary cleft, serving as a landmark for some CPR procedures, is known as the "intermammary line".
A review of historical literature shows that Spence himself never wrote that adipose or breast-tissue extends into the axilla. He only published that surgeons should not operate on breast cancer if they found "an undefined tail-like projection creeping up from the breast towards the axilla”, as though referring to the tumor tissue itself.

From the cosmetological point of view, it is an important aesthetic component of the breast which should be taken into consideration during various kinds of breast surgery. [1] [2] Histologically, the inframammary fold is an intrinsic dermal structure consisting of regular arrays of collagen held in place by a specialized superficial fascia ...
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.
Afterwards, the patient is laid supine, and the excess breast skin is cut; to avoid a scar at the inframammary fold, a purse-string closure gathers the excess folds of skin at the lower pole of the breast; in due course, the three joined pillars of skin will integrate to the inframammary fold. Again, the supine patient is elevated to a sitting ...
The pectoralis major receives dual motor innervation by the medial pectoral nerve and the lateral pectoral nerve, also known as the lateral anterior thoracic nerve. The sternal head receives innervation from the C7, C8 and T1 nerve roots, via the lower trunk of the brachial plexus and the medial pectoral nerve. The clavicular head receives ...
The mammary ridge is primordial for the mammary glands on the chest in humans, and is associated with mammary gland and breast development.. In human embryogenesis, the mammary ridge usually appears as a narrow, microscopic ectodermal thickening during the first seven weeks of pregnancy and grows caudally as a narrow, linear ridge. [1]
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.
