| Question | Answer |
|---|---|
| glands without ducts-make hormones | Endocrine System |
| glands with ducts make other substances-not hormones | Exocrine System |
| 1: sweat 2:oil 3:tears 4:salivary amylase HCl producing glands (oxyntic) of the stomach 5: digestive enzymes 6:bile (emulsifies fats) produce cerumen (ear wax) | 1:Sudoriferous glands 2:Sebaceous glands 3:Lacrimal glands 4:Salivary glands 5:Pancreas 6:Liver 7:Cerumenous glands |
| (third eye) melatonin | Pineal gland |
| monitors many bodily functions, contains appetite and thirst centers, regulates temperature, via hormones and neurological signals controls pituitary gland, portion of sex drive | Hypothalamus |
| (neurohypophysis)-1) ADH (anti-diuretic hormone, vasopressin)-controls urinary output by kidneys-suppressed by alcohol consumption. Deficiency causes diabetes insipidus | Posterior pituitary |
| causes uterine contractions during labor, snuggle (cuddle) hormone, causes release of milk from mammary glands | oxytocin |
| produces 7 hormones | Anterior pituitary |
| stimulates milk production by mammary glands. Produced by LACTOTROPHS. | Prolactin |
| stimulates thyroid to produce T3 (triiodothyronine) and T4 (Thyroxine) (thyroid hormones). Produced by THYROTROPHS. Is a TROPIN (a hormone that causes the production of another hormone). | Thyroid Stimulating Hormone (TSH) |
| in females stimulates the ova in the ovarian follicles to “ripen” and causes production of estrogen by the theca interna of the follicle.In males, works in conjunction with testosterone to form sperm. Produced by GONADOTROPHS | Follicle Stimulating Hormone (FSH) |
| in females causes ovulation and production of progesterone and estradiol (estrogen) by the corpus luteum (yellow body) (empty follicle) in the ovary; in males stimulates Leydig cells in testes to produce testosterone. Produced by GONADOTROPHS. | Leutenizing hormone (LH) |
| causes production of melanin (skin pigment) by melanocytes. Produced by CORTICOTROPHS. | Melanocyte Stimulating Hormone (MSH) |
| stimulates the adrenal glands (the cortex) to produce corticosteroid, mineralocorticoid and glucocorticoid hormones. Produced by CORTICOTROPHS. | Adrenocorticotropic Hormone (ACTH) |
| produced in the greatest quantity by the anterior pituitary. Has receptor sites on ALL cells of the body for growth and repair. Increases glycogenolysis , inhibits protein breakdown, enhances amino acid entry into cells. Produced by SOMATOTROPHS. | Somatotropin (hGH, human growth hormone)- |
| Through genetic engineering in bacteria, this has been produced to enhance the size and milk production in cows. | recombinant bovine somatotropin |
| Deficiency in somatotropin causes | pituitary dwarfism |
| excess amount of somatotropin can cause both | gigantism and diabetes mellitus |
| A dwarfism that is not associated with hGH is | ACHONDROPLASTIC DWARFISM |
| only gland that stores hormones (T3-triiodothyronine and T4-thyroxine up to 100 days). Produced by FOLLICULAR CELLS. | THYROID GLAND |
| tiredness,weight gain, dry skin and hair, brittle nails, slow heart rate,depression, always cold myxedema. Might develop a GOITER (usually associated with an iodine deficiency Babies develop CRETINISM | Hypothyroidism (too little) |
| Weight loss, always hot ,nervous ,rapid heart rate (with arrhythmias) ,oily skin and hair | Hyperthyroidism |
| the body produces antibodies to the thyroid gland that resemble TSH, but are not under any feedback control. In addition to the above symptoms, patients also suffer with EXOPHTHALMOS. | Graves’ Disease |
| Antibodies are produced against the thyroid tissue (anti-peroxidase antibody) and against the thyroid hormones themselves (anti-thyroglobulin antibody). | Hashimoto’s Thyroiditis |
| Produced by the thyroid.This hormone helps to deposit calcium into bones | CALCITONIN |
