Somatostatin Study guides, Class notes & Summaries

What is a hormone and how does it act? Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. What is a paracrine gland? a secretion that enters interstitial fluid but affects only neighboring cells What is an autocrine gland? A secretion that only affects the secreting cell. What is an en...
