B) Initiates the secretion of LH and FSH
C) Is released in a continuous concentration from the hypothalamus

Answer 1

Acts upon the posterior pituitary

Question 2

The difference between the receptors of peptide hormones and steroid hormones is:

A) There is no difference between the two types of receptors.
B) The receptors for peptide hormones are on the cell surface, whereas receptors for steroids are within the cell.
C) The receptors for peptide hormones can also receive steroid hormones, whereas the receptors for steroid hormones cannot.
