IBCLC - Breast Anatomy, Development and Physiology fully solved 2024/2025

IBCLC - Breast Anatomy, Development and PhysiologyOxytocin - released from *posterior pituitary* - correct answer *Stimulates Milk Ejection Reflex* - released in a pulsatile fashion, with maternal blood levels remaining elevated for about 1.5 to 2 minutes *Multiple milk ejections may occur during a breastfeed w/ first one experienced within the first minute* - both breasts are affected simultaneously, with milk movement towards the nipple evident in both breasts. - Infant milk intake is associated with number and duration of milk ejections - causes increased uterine activity, reducing the risk of haemorrhage - causes the skin temperature of the mother's breast to rise, providing warmth to the infant *decreases maternal anxiety and increases calmness; enhances parenting behaviours* causes thirst Prolactin - released from *anterior pituitary* - correct answer Stimulates lactogenesis and initiates milk secretion. Released by *anterior pituitary* Tanners's phases of breast development - correct answer 5 phases of breast development - part of Mammogenesis Axillary Nodes - correct answer A group of lymph nodes located in the axillary (or armpit) region of the body. They perform the vital function of filtration and conduction of lymph from the upper limbs, pectoral region, and upper back. - *collect most of the lymph drainage from the lactating breast*
