| Question | Answer |
|---|---|
| Endocrine Glands | Cells secrete their products into interstital fluid (the fluid that surrounds tissue cells). Then the hormones diffuse into capillaries and blood carries them throughout the body. |
| Exocrine Glands | Secrete their products into ducts that carry them into a body cavity, into the lumen of an organ, or onto the outer surface of the body. |
| Role of Target Cells and Receptor Sites | Target cells respond when they come into contact with hormones. Recptors bind and recognize the hormone. |
| Locations of Receptor Sites for Lipid and Water Soluble Hormones | Lipid Soluble Site: receptors within the target cell Water Soluble Site: receptors tha protrude from the target cell surface |
| 3 Ways Hormone Secretions are Controlled | 1. Signals from the nervous system 2. Chemical changes in the blood 3. Other hormones |
| Human Growth Hormone (hGH) | Causes the production of IGH (insulinlike growth hormone) which causes the body cells to duplicate |
| Thyroid-Stimulating Hormone (TSH) | Stimulates the secretion and synthesis of thyroid hormones by the thyroid gland |
| Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH) | FSH-stimulates reproductive organs to produce follicles & stimulates sperm production in males. LH-Stimulates the female reproductive organs to begin ovulation & promotes the production of estrogen & progesterone.Stimulates testosterone in males. |
| Prolactin (PRL) | Triggers milk production in the mammery glands |
| Oxytocin | Stimlulates the uterine contrations during labor and stimulates lactation in the mammery glands |
| Antidiuretic Hormone (ADH) | Causes the kidneys to retain more water, increasing the urin volume, constricts arterioles, and raising BP |
| Thyroxine (T4) and Triiodothyronine (T3) | Controls the basal metabolic rate, the body energy used, temperature and cell metabolism |
| Glucagon | Increases blood glucose level when it is too low |
| Insulin | Lowers blood glucose level when it is too high |
| Cortisol | Promotes protein breakdown, breakdown of triglycerides, and decreases inflammation caused by white blood cells |
| Epinephrine | Increases the functions for the Flight or Fight syndrome and works mostly on the heart pumping blood |
| Norepinephrine | Same are Epinephrine but works on the rest of the body rather then just the heart |
| Estrogen and Progesteron | Female sex hormones that regulate the menstual cycle, maintain pregnancy and promotes lactation. Also establish and maintain the feminine body shape |
| Cushings Disease | Cause: Caused by having too much cortisol Symptoms: Spindly arms and legs, a rounded "moon face", humpon back and hanging abdomen |
| Addisons Disease | Cause: Caused by having too little cortisol Symptoms: Mental lethargy, anorexia, nausea and vomiting, weight loss, hypoglycemia, and muscular weakness |
| Type I Diabetes | Cause: Causes bu having not enough insulin because the pancreas is insufficient Symptoms: the beta cells have been destroyed |
| Type II Diabetes | Cause: By having too high blood glucose because the target cells are insufficient Symptoms: overweight |
| Hyperinsulinism | Cause: By having too low blood glucos because there is too much insulin in the blood Symptoms: hypoglycemia |
| lact(o) | milk |
| acromegaly | enlarged and distorted extremities of the face |
| acidosis | accumulation of acids in the blood |
| anorexia | loss of appetite |
| cachexia | state of malnutrition, wasting |
| diaphoresis | excessive sweating |
| emaciation | extremely thin, wasting |
| gangrene | death of tissue secondary to low oxygen levels |
| hypophysectomy | removal of pituitary gland |
| neurophathy | disease of nerves, commone with diabetes |
