Which hormone causes strong uterine contractions during birth?
Options:
Answer:
A
Solution:
Oxytocin is synthesized by the hypothalamus and is transported axonally to the neurohypophysis (posterior pituitary). During parturition (childbirth), it acts on the smooth muscles of the uterus and stimulates strong uterine contractions.
LH (Luteinizing Hormone) induces ovulation of fully mature follicles (Graafian follicles) and maintains the corpus luteum.
FSH (Follicle Stimulating Hormone) stimulates the growth and development of ovarian follicles in females.
Prolactin regulates the growth of the mammary glands and the formation of milk in them.
Answer: Oxytocin
