Breast development
Breast Development
Breast development, also known as mammary gland development, is a complex biological process that occurs primarily in female mammals, although it also occurs in a rudimentary form in males. The process is regulated by a variety of hormones, including estrogen, progesterone, and prolactin.
Pronunciation
Breast Development: /ˈbrɛst dɪˈvɛləpmənt/
Etymology
The term "breast" comes from the Old English "brēost," which means "chest, womb, abdomen." The term "development" comes from the Old French "desveloper," which means "unwrap, unfurl."
Stages of Breast Development
Breast development occurs in distinct stages, as outlined by the Tanner scale. These stages include:
- Prepubertal Stage: This is the stage before puberty begins. The breasts are flat and only the tip of the nipple is raised.
- Budding Stage: This is the first visible sign of puberty. Small bumps (buds) begin to form under the nipple, which may cause the nipple and the areola to swell.
- Growth Stage: The breasts and areolas continue to enlarge, although they do not yet have a rounded shape.
- Mature Stage: The breasts become fully rounded and only the nipples are raised.
