|---|---|
 Endocrine System | slower to respond, long-lasting effects, hormones & target tissues, hypothalamus |
| Nervous System | fast acting, nerve impulses, hypothalamus |
| Pituitary gland | master gland |
| Thyroid | secretes thyroxin, controls metabolic rate |
| Testies | testosterone/androgens |
| Parathyroid | for glands embedded in the thyroid; secretes parathormone; controls announces level of calcium and phosphate (which influence levels of excitability) |
| Adrenal | gland which increases heart rate, blood pressure, and breathing rate |
| Pancreas | located partially behind the stomach in the abdomen, and it functions as both an endocrine and exocrine gland. It produces digestive enzymes as well as insulin and glucagon |
| Ovaries | located one on each side of the uterus in the female pelvis, functioning to secrete estrogen and progesterone |
| Thymus | the primary gland of the lymphatic system, located within the mediastinum; helps maintain the body's immune response by producing T lymphocytes |
| Steriods | estrogen, testosterone, aldosterone, cortisol, cholesterol |
| Amino acid-based | Amines, thyroxine, peptide, and protein hormones |
| Target cells | cells that have receptors for a particular hormone |
| hormones | chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues |
| Negative feedback mechanisms | The most common homeostatic control mechanism. The net effect is that the output of the system shuts off the original stimulus or reduces its intensity. |
| Pineal body | a structure found between the cerebral hemispheres of vertebrates; secretes melatonin |
| Oxytocin | stimulates contraction of uterus and the milk "letdown" reflex; pituitary |
| ADH | hormone that increases the reabsorption of water; pituitary |
| Growth hormone | a hormone produced by the anterior pituitary gland, Stimulates growth and metabolism |
| Prolactin | Stimulates milk production; anterior pituitary |
| Thyroxine | hormone produced by the thyroid glands to regulate metabolism |
| Calcitonin | reduces blood calcium level; thyroid |
| PTH | increases blood calcium level; parathyroid |
| Insulin | Pancreas; protein hormone that helps to decrease blood sugar |
| Glucagon | a hormone secreted by the pancreas, Raises blood glucose |
| Testosterone | affects masculinization and reproduction; testies |
| Androgens | Support sperm formation; development and maintenance of male secondary sex characteristics; testies |
| Estrogens | stimulate uterine lining growth; development and maintenance of female secondary sex characteristics |
| Progesterone | promotes growth of uterine lining; Ovaries |
