A) melanocyte stimulating hormone and growth hormone; posterior pituitary hormones are released in response to circadian rhythms
B) LH and FSH; posterior pituitary hormones are released at puberty
C) epinephrine and norepinephrine; posterior pituitary hormones are released following neural stimulation by the SNS

Question

Quizplus · Accepted Answer

The posterior lobe of the pituitary gland releases ADH (antidiuretic hormone) and oxytocin, which are actually produced in the hypothalamus and then transported down the pituitary stalk to be released directly from the posterior pituitary. This differs from the anterior pituitary hormones, which are regulated by releasing and inhibiting hormones from the hypothalamus.
