Title: If oxytocin receptors are blocked? Post by: buhneeduh1218 on Sep 2, 2012 A) the mammary glands will not secrete milk.
B) the mammary glands will be replaced by connective tissue. C) milk will not be ejected into the lactiferous sinuses. D) the menses will begin. E) the mammary glands will produce only colostrum.

Stimulation of milk ejection (milk letdown): Milk is initially secreted into small sacs within the mammary gland called alveoli, from which it must be ejected for consumption or harvesting. Mammary alveoli are surrounded by smooth muscle (myoepithelial) cells which are a prominant target cell for oxytocin. Oxytocin stimulates contraction of myoepithelial cells, causing milk to be ejected into the ducts and cisterns. http://www.vivo.colostate.edu/hbooks/pathphys/endocrine/hypopit/oxytocin.html |
