a. pituitary.
b. hypothalamus.
c. thyroid.
d. gonads. 2 points save answer

The answer is letter b, the hypothalamus. Puberty's trigger lies in a small part of the brain called the hypothalamus, a gland that discharges gonadotropin-releasing hormone (GnRH). GnRH arouses the pituitary gland, a pea-sized organ connected to the bottom of the hypothalamus, to emit two hormones: luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These two hormones motion the female and male sex organs to begin releasing the appropriate sex hormones, including estrogens and testosterone, which unveil the other signs of puberty in the body.
