Nipple Breast

The breast nipple (lat. papilla mammae) is a physiological element of the mammary gland (lat. mammula), the most prominent and noticeable element of the female breast (lat. mamma).

The mammary glands are located under the skin. Between the large muscles lies a layer of fat. Laying down on the bed, the chest fills with blood. The papillae enlarge and harden. It is through them that feeding occurs.

The nipple plays a huge role during feedings. It stimulates milk production. This is the main organ of lactation. It maximizes the flow and reduces the outflow of milk. Milk penetrates inside through it.

The length of the female nipple varies from 2 to 3.5 cm, width - 0.4-1 cm. The size of the nipples does not depend on the volume of the mammary glands. The diameter of the mammary gland in women is from 1 to 18 cm. The size of the male nipple is 6 mm, diameter is up to 6 cm.
