A woman's nipple is able to produce milk because it has many little holes that are connected to milk glands in the breast (they are actually somewhat analogous to sweat glands). Tiny muscles contract when stimulated (typically by a sucking sensation on the nipple), and thus squeeze the milk from the glands.
Each breast contains a cluster of alveoli or sacs in which milk is produced. The alveoli release the milk into ducts, which work like pipes to take the milk to the nipples Mammary glands produce milk in mammals.
Only mammals produce milk.
Yes, cows typically produce more milk than calves need, as they are bred to produce milk for human consumption as well.
The inside of a female breast is mostly fatty tissue (glandular tissue and adipose tissue) with a gland in the center (the mammary gland) that goes to the nipple. Use the link below to see a diagram and learn more.
A supernumerary nipple (also known as a third nipple, accessory nipple, polythelia or polymastia) is an additional nipple occurring in mammals including humans. Often mistaken for moles, supernumerary nipples are diagnosed at a rate of 2% in females, less in males. The nipples appear along the two vertical "milk lines" which start in the armpit on each side, run down through the typical nipples and end at the groin. They are classified into eight levels of completeness from a simple patch of hair to a milk-bearing breast in miniature. Polythelia refers to the nipple alone while polymastia denotes the presence of glandular tissue. Sourced from: http://www.elresearch.com/Polythelia Hilarious...
No because if the boyfriend s_ucks their nipple the boyfriend gets the milk.
Yes, Enrique Iglesias is known for having lots of chest muscle but can produce breast milk. His breast milk is actually Spanish milk. It is hard for him to produce milk because of his breast size and the nipple is folded under his chest
The level of hormones that produce lactation is high.
The nipple feeds by providing mother's milk for the infants. The milk is produced within the glands of the breast and come through the tip of the nipple.
When girls become mothers they use their breasts to produce milk for their babies. The material in their breasts turns into milk.
No, you cannot get any STDs from sucking on a person's nipple. However, you can get STD's through breast milk.
Milk is transported to the nipple through a network of ducts in the breast known as milk ducts. During breastfeeding or pumping, the hormone oxytocin stimulates the muscles around these ducts to contract, pushing the milk toward the nipple. The milk is stored in the lactiferous sinuses, which are reservoirs located just beneath the nipple, ready to be released when the baby latches on or when expressed.
Virgin girls don't normally produce milk. If that is happening, see a doctor.
They are mamary glands, after pregnancy they produce milk which is used to feed babies.
There's a dent at the center of the nipple where milk comes out if needed.
The breasts have what is called mammary glands in them. When puberty begins the breasts normally enlarge from the hormone, (O)estrogen. The breasts have a series of tubes that radiate from the common center, ie' the nipple, where a number of slight nodules on the areola are formed by the milk glands under the surface of the skin. The tubes, ranging from 15 to 20 extend from the lobes of the breast and open at the nipple. When a breast is inactive, no pregnancy, is consists of mainly connective tissue and fat. During pregnancy, or attempting to induce lactation, the breasts enlarge and the mammary glands become active and when sufficient levels of the hormone required to trigger milk production, is present, milk is released into tiny ducts where stimulation of the nipple and areola may cause the milk to be ejected from the nipple. Additionally, Note, that a woman does not have to be pregnant, or have had a child for this to happen, it may also happen due to the effects of a hormone imbalance which may be unexplainable, caused by a pituitary tumor, or caused by regular nipple stimulation. Some women have started lactating by heavy nipple play alone.
They don't until they get pregnant. Though milk can be produced when not pregnant, females do not have an age at which they start to produce.
