Question

Choose the correct combination of labelling of the hormonal control of female reproductive system.

• A. (a)- GnRH, (b)- TSH, (c)- LTH, (d)- uterus
• B. (a)- GnRH, (b)- LH/FSH, (c)- oestrogen or progesterone, (d)- uterus
• C. (a)- GnRH, (b)- STH, (c)- LH, (d)- uterus
• D. (a)- GnRH, (b)- ACTH, (c)- LH, (d)- uterus
• E. (a)-GnRH, (b)- LTH, (c)- oestrogen (d)- uterus

Answer 1

Answer: (B)

(a)- GnRH, (b)- LH/FSH, (c)- oestrogen or progesterone, (d)- uterus

The hypothalamus secretes gonadotropin releasing hormone (GnRH) which stimulates the anterior pituitary gland to release follicle stimulating hormone (FSH)/ LH. The FSH stimulates the secretion and synthesis of estrogens and/or progesterone which in turn acts upon uterus.
So, the correct answer is option B.
