QUESTION
Oxytocin has specific effects on?
OPTIONS
(A) Smooth muscles of uterus
(B) Myoepithelial cells of mammary gland
(C) Facilitates parturition
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
Oxytocin stimulates contraction of uterine smooth muscle and mammary myoepithelial cells. Uterine contractions help fetal expulsion during parturition, while mammary contractions produce milk ejection. Thus, both listed target tissues and the stated obstetrical effect are valid. Choosing only one would omit another established physiological action, making all of the above the most complete response.
