Nipple

nipplesteatsNipple erection
The human areola (areola mammae, or ) is the pigmented area on the breast around the nipple. The size and shape of areolae and nipples are also highly variable, with those of women usually being larger than those of men and prepubescent girls.
The nipple is surrounded by the areola, which is often a darker color than the surrounding skin.

Breast

The nipple of the breast is surrounded by the areola (nipple-areola complex).

Lactiferous duct

milk ductsmilk ductductal
The mature human female nipple has several small openings arranged radially around the tip of the nipple (lactiferous ducts) from which milk is released during lactation.
Prior to 2005, it was thought within the areola the lactiferous duct would dilate to form the lactiferous sinus in which milk accumulates between breastfeeding sessions.

Areolar gland

Glands of MontgomeryMontgomery's glandsMontgomery gland
Other small openings in the areola are sebaceous glands, known as Montgomery's glands.
Areolar glands or Glands of Montgomery are sebaceous glands in the areola surrounding the nipple.

Lactation

The mature human female nipple has several small openings arranged radially around the tip of the nipple (lactiferous ducts) from which milk is released during lactation.
Suckling by the baby innervates slowly-adapting and rapidly-adapting mechanoreceptors that are densely packed around the areolar region.

Sebaceous gland

Other small openings in the areola are sebaceous glands, known as Montgomery's glands.
The areolar glands are in the areola that surrounds the nipple in the female breast.

Breastfeeding

Breastfeeding by the baby innervates slowly adapting and rapidly adapting mechanoreceptors that are densely packed around the areolar region.
Pigmentation of the nipples and areola also increases.

Latch (breastfeeding)

Infants sometimes create trauma to the nipple and areolae by latching-on of the infant.
In a good latch, both the nipple and a large portion of the areola are in the baby's mouth.

Paget's disease of the breast

Paget's diseasePaget's disease of the nippleMammary Paget’s disease
Paget's disease of the breast is a malignant condition that outwardly may have the appearance of eczema, with skin changes involving the areola and nipple.
Cancer cells disrupt the normal epithelial barrier and extracellular fluid accumulates on the surface of the skin, resulting in the crusting of the areola skin.

Tanner scale

Rated according to the Tanner scale of physical development, in stage four, the areolae are raised.

Chocolate (color)

The areolae can range from pink to red to chocolate brown to dark brown or nearly black, but generally tend to be paler among people with lighter skin tones and darker among people with darker skin tones.

Human areolae are mostly circular in shape, but many women have large areolae that are noticeably elliptical.

Diameter

The average diameter of male areolae is around 28.0 mm.

Cracked nipple

A function of the specialized dermis of the areola is to protect the regular breast skin from wear, cracking, and irritation.

Mechanoreceptor

Breastfeeding by the baby innervates slowly adapting and rapidly adapting mechanoreceptors that are densely packed around the areolar region. Another function of an areola is to house slowly-adapting mechanoreceptors that trigger oxytocin excretion during nursing.
