Final Answer : A, Explanation :  Anterior pituitary hormones are proteins or glycoproteins, such as growth hormone, prolactin, and others. They are transported via the bloodstream, not the hypothalamohypophysial portal system, which is for hypothalamic hormones. They bind to cell surface receptors, not intracellular ones, and typically have shorter half-lives than hours. Their release is regulated by hypothalamic hormones, not directly by action potentials.
