QUESTION
The hormone which is essential for cervix dilation is?
OPTIONS
(A) Oxytocin
(B) L.H.
(C) F.S.H
(D) Relaxin
ANSWER
(D) Relaxin
EXPLANATION
Relaxin promotes remodeling and softening of cervical connective tissue and relaxation of pelvic structures around parturition. Oxytocin chiefly stimulates myometrial contractions rather than being the primary connective-tissue relaxing hormone. LH regulates ovulation and luteal function, while FSH supports follicular development. Cervical dilation involves several coordinated signals, but relaxin is the best match for the function asked here.
