Milk-producing glands in the breast that are responsible for synthesizing and secreting milk.

Specialized cells lining the alveoli that synthesize the components of milk.

Hormone responsible for stimulating breast growth and milk production during pregnancy.

The process of milk production in the breast.

The process of milk production in the breast is influenced by hormones such as Progesterone, Estrogen and Placental Lactogen (HPL), which work together to prepare the breast for lactation.

The area around the nipple, which becomes darker and wider during pregnancy.

Small bumps around the areola that secrete an oily substance to protect the nipple during breastfeeding.

The fluid that is produced by the breast before and after birth, containing antibodies and nutrients.

The process of milk moving from the alveoli to the nipple.

The structure that carries milk from the alveoli to the nipple.

Sebaceous glands around the nipple that enlarge during pregnancy and secrete lubrication to protect the nipple during breastfeeding.

Suckling sends signals to the hypothalamus, regulating milk production and mother's behavior.

A recent anatomical study redefined the breastfeeding breast by showing that milk ducts branch closer to the nipple, compared to previous understanding.

Ultrasound imaging of lactating women revealed that milk ducts branch close to the nipple, contrary to the previous theory.

The structures previously understood as lactiferous sinuses have been debunked. There is now a consensus that these structures are not anatomically present in the lactating breast.

The distribution of glandular tissue in the breast is no longer considered even. Research shows that 65% of this tissue is concentrated within 30 mm of the nipple.

Contrary to previous assumptions, the network of ducts in the breast is not always radial or symmetrical. The structure can vary in a non-uniform pattern.

The number of ducts exiting the nipple has been revised downwards. Current research estimates the average number to be 9, ranging from 4 to 18.

Cooper's ligaments are fibrous structures that provide support and elasticity to the breast. They are located in the retromammary fat, behind the glandular tissue.

Retromammary fat is a layer of adipose tissue located behind the glandular tissue in the breast. It helps to cushion and insulate the breast.

Glandular tissue is the primary functional component of the breast. It is responsible for milk production and consists of lobules and alveoli.

Intraglandular fat is adipose tissue found within the glandular tissue of the breast. It helps to support and maintain the structure of the lobes and lobules.
