Study Notes
Anatomy
- The breast is a glandular organ located on the chest wall, consisting of:
- Adipose tissue (fat)
- Glandular tissue (lobules and ducts)
- Connective tissue (ligaments and Cooper's ligaments)
- The breast is divided into four quadrants:
- Upper outer quadrant
- Upper inner quadrant
- Lower outer quadrant
- Lower inner quadrant
Function
- The breast is responsible for:
- Producing milk for lactation (nourishment of offspring)
- Regulating hormones (estrogen and progesterone)
Development
- Breast development occurs during:
- Embryonic development (week 6-8)
- Puberty (estrogen and progesterone influence)
- Pregnancy (hormonal changes)
Changes During Life Stages
- Puberty: Breast buds form, and estrogen and progesterone stimulate growth
- Pregnancy: Hormonal changes prepare the breast for lactation
- Lactation: Milk production and secretion
- Menopause: Hormonal changes lead to breast tissue atrophy
Clinical Relevance
- Breast cancer: Most common cancer in women, affecting glandular tissue
- Breastfeeding: Important for infant nutrition and bonding
- Breast cosmetic procedures: Augmentation, reduction, and reconstruction for aesthetic or functional purposes
