Breast development begins duing the fetal stage

At the ducts ends of the nipples, there are lactiferous sinuses to store the milk.

Initially, both men and women have the [blank_start]same[blank_end] inactive breasts. It is not until [blank_start]puberty[blank_end] that breasts begin to differentiate. The hormones [blank_start]estrogen[blank_end] (encourages cell growth) and [blank_start]progesterone[blank_end] (muscle relaxant) cause breast maturation. Women begin to develop [blank_start]glandular[blank_end] [blank_start]tissue[blank_end], which contains [blank_start]glands[blank_end]--which contain the cells needed to produce [blank_start]milk[blank_end].

Progesterone is a muscle relaxant and specifically allows breast development by

At the end of every menstrual cycle, the alveolar buds retreat and "close up" again.

Due to the hormonal peaks of (alphabetical order) [blank_start]estrogen[blank_end] and [blank_start]progesterone[blank_end], breast [blank_start]tenderness[blank_end] can coincide with [blank_start]ovulation[blank_end]. This is because the hormones are causing the [blank_start]lactiferous[blank_end] [blank_start]ducts[blank_end] within the breast to grow more as well as the [blank_start]alveolar[blank_end] [blank_start]buds[blank_end] to open up in anticipation of producing milk.

What is true regarding Sir Atley Cooper's model of breast?

The [blank_start]Tanner[blank_end] stages are a way to measure proper breast development.

Which of these are pregnancy changes in breasts?

At roughly week [blank_start]16[blank_end] during pregnancy, the breast will start producing [blank_start]colostrum[blank_end], which is essentially a milk precursor. This [blank_start]sticky[blank_end] substance will continue to be produced until the first incident of infant [blank_start]suckling[blank_end], which will then enable milk production ([blank_start]lactation[blank_end]) to take place.

Once parturition happens, two hormones play pivotal roles. Within the breast, [blank_start]prolactin[blank_end] causes milk to be produced and then released into the [blank_start]ducts[blank_end]. Then, upon the infant [blank_start]suckling[blank_end], [blank_start]oxytocin[blank_end] causes the external release and also the final step of lactation--[blank_start]milk[blank_end] [blank_start]ejection[blank_end].

Label the stages--> pay attention to how the breast looks not just within but also externally (the answers can be more than 1 word)

Which of these contribute to neo natal immunity?

IgA specifically provides protection within...

Within the alveolar buds: [blank_start]Lactocytes[blank_end] actually make the milk. These are surrounded by [blank_start]myoepithelial[blank_end] cells, which contract and squeeze the milk into the ducts. These contractile cells contract when they receive the hormonal [blank_start]let[blank_end]-[blank_start]down[blank_end] reflex.

Hormonal basis for Lactational amenorrhea (all lower case, no prepositions)

Suckling causes [blank_start]turgor[blank_end] pressure, which leads to [blank_start]prolactin[blank_end] being promoted and milk being produced.
