Incorrect statement regarding lactation
-
Incorrect statement: IgG provides active immunity through colostrum to newly born
Explanation
-
Correct statement: IgG is not present in colostrum. Instead, colostrum contains high levels of IgA, which is the primary antibody providing passive immunity to the newborn.
- IgG is a different type of antibody that is transferred to the fetus through the placenta during pregnancy, providing passive immunity before birth.
- Colostrum is the initial secretion from the mammary glands soon after parturition, rich in antibodies, growth factors, and nutrients essential for the newborn's health.
- Oxytocin is the hormone responsible for milk let-down, causing the contraction of smooth muscle cells around the alveoli to release milk into the ducts.
- Milk let-down is a neuro-endocrine reflex involving both neural and hormonal responses to stimuli such as suckling, leading to the release of milk from the mammary glands.
