Which is true statement about Anterior Pituitary Hormones?

(A) Secretion of anterior pituitary hormones is pulsatile # Secretion of anterior & posterior pituitary hormones, adrenal glucocorticoids, mineralocorticoids and catecholamines, gonadal sex steroids, parathormone, insulin and glucagon is pulsatile (burst-like or episodic).> Neuronal inputs, cellular excitability and feedback with time delays constitute proximate mechanisms driving recurrent pulses.> Both the amplitude and frequency of gonadotropin, thyrotropin, prolactin and sex-steroid pulses determine their mean concentrations.> In contradistinction, primarily the amplitude of growth hormone, adrenocorticotropin, cortisol, parathormone and insulin pulses controls their average values.> Gonadotropin-releasing hormone and growth-hormone pulses convey unique signaling information to target tissues.
