what is colostrum? how is milk production hormonally regulated?
Answers
Explanation:
Colostrum is the first milk produced by the mother's mammary glands. It is thick and yellowish in color. It contains some of the very important antibodies, important for the survival of the newborn. The hormone prolactin, that is secreted by the pituitary gland is responsible for the milk production.
Answer:
Colostrum (also known as beestings or first milk) is a form of milk produced by the mammary glands in late pregnancy and the few days after giving birth. Human and bovine colostrums are thick, sticky and yellowish. In humans, it has high concentrations of nutrients and antibodies, but it is small in quantity.
Lactation is controlled by hormones from several endocrine glands. An undisturbed function of the anterior pituitary, of the adrenals, and of the ovaries is a prerequisite for a normal morphogenesis of the mammary gland. The epithelial ducts proliferative under the combined influence of estrogens, glucocorticoids and growth hormone, whereas the lobuloalveolar development depends on progesterone and prolactin in addition to the fore-mentioned hormones.
