Question

Starting with the hypothalamus, place the organs in order to represent the hierarchy of hormonal control involved in the sexual cycle?

1) Hypothalamus, Pituitary gland, Ovaries, Uterus
2) Pituitary gland, Hypothalamus, Ovaries, Uterus
3) Ovaries, Hypothalamus, Pituitary gland, Uterus
4) Uterus, Ovaries, Pituitary gland, Hypothalamus

Answer 1

The correct hierarchy of hormonal control in the sexual cycle is Hypothalamus, Pituitary gland, Ovaries, and Uterus. This starts with GnRH from the hypothalamus, stimulating the pituitary to release FSH and LH, which then act on the ovaries to produce sex hormones affecting the uterus.

Step-by-step explanation:

To represent the hierarchy of hormonal control involved in the sexual cycle starting with the hypothalamus, it is as follows: 1) Hypothalamus, Pituitary gland, Ovaries, Uterus. The process starts with the hypothalamus releasing gonadotropin-releasing hormone (GnRH). This stimulates the pituitary gland to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn act on the ovaries to produce estrogen and progesterone. These sex hormones have various effects including the preparation of the uterus for pregnancy. Therefore, the correct order is Hypothalamus, Pituitary gland, Ovaries, and Uterus.
