 Hormones Hormones are chemicals synthesized by the endocrine glands that are secreted in the bloodstream. Hormones affect the brain and many other tissues of the body. For example, adrenaline increases heart rate, blood pressure, blood sugar, and feelings of excitement during emergency situations.  Hormones vs. Neuros Released Released in in Chemical blood stream brain by Epinephrine neurons by glands (adrenal gland Slow Aka: adrenaline) Fast acting Norepinephrine acting Longer Shorter lasting lasting  The Endocrine System The Endocrine System is the body’s “slow” chemical communication system. Communication is carried out by hormones synthesized by a set of glands.  Pituitary Gland Is called the “master gland.” The anterior pituitary lobe releases hormones that regulate other glands. The posterior lobe regulates water and salt balance. Thyroid & Parathyroid Glands Regulate metabolic and calcium rate.  Adrenal Glands Adrenal glands consist of the adrenal medulla and the cortex. The medulla secretes hormones (epinephrine and norepinephrine) during stressful and emotional situations, while the adrenal cortex regulates salt and carbohydrate metabolism.  Gonads Sex glands are located in different places in men and women. They regulate bodily development and maintain reproductive organs in adults.
