Biology ESystem
chapter 3
| Question | Answer |
|---|---|
| exocrine gland | produces molecules produced in the glands, not secreted to the blood |
| endocrine gland | produces molecules produced in the glands, secreted to the blood |
| gland shrinks with age | thymus |
| gland affected by the levels of iodine in your diet | thyroid |
| Why homeostatic regulation of calcium levels so important | increase blood calcium levels |
| prostaglandins | local hormones produced by tissues, used local targets |
| gland serves as master control system of the E system | hypothalmus |
| hormone | a molecule that travels through the blood stream to a target in the body |
| steroid hormone | derived from cholesterol; altering the gene expression of the cell |
| steroid hormone function | enters all cells, steroid receptor complex enters the nucleus |
| peptide | hormone is composed of amino acids or proteins, non-steroid hormones are more common than steroids |
| prostaglandins | local hormones produced by tissues made of fatty acids/lipids, work at local targets |
| camp | created when atp has two PO4 molecules removed, also called a master molecule |
| Hormones in the Hypothalamus | RH-releaseing hormone IH- inhibiting hormone |
| Hormones in Anterior Pituitary | TSH-thyroid stimulating, ACTH-adrenocortictropic, FSH, LH, PRL-prolactin GH-growth, Endorphins |
| Hormones in Posterior pituitary | ADH,- anit-diuretoc hormone, oxytocin |
| Hormone in Pineal gland | Melatonin |
| Hormones in Thyroid gland | Thyroxines and Calcitonin |
| Hormones in Parathyroids | PTH-parathyroid hormone |
| Hormone in Thymus | Thymosins |
| Hormone in heart | ANP-atrial natiuretic peptides |
| Hormones in pancreas | Insulin, glucagon |
| Hormones in stomach | gastrin, ghrelin |
| Hormones in Small intesine | secretin, cholecystokinin |
| Hormones in Kidneys? | EPO-erythropoietin, cacitriol |
| homrones in adrenal cortex | aldosteron, androgens, glucocorticoids |
| Hormones in adrenal medulla | adrenaline, noradrenaline |
| hormones in ovaries | estrogen, progesterone |
| hormones in testes | testosterone |
| Thyroid stimulating hormone | stimulates thyroid gland |
| adrenocorticotropic hormones | stimulates adrenal glands |
| follicle stimulating hormones in women | stimulates follicle growth in ovaries |
| follicle stimulating hormones in men | assist along with testosterone in spern production in testes |
| luteinizing hormone (LH)women | hormone causes ovulation |
| luteinizing hormone (LH) | allows for production of testosterone |
| Prolactin (PRL) women | lactation, high levels can interfere with other sex hormones |
| Prolactin (PRL) men | high levels may be involved with infertility |
| Growth hormone | regulates growth and aspects of metabolism and cellular functions, decreases with agemay help in healing process |
| Endorphins | natural pain inhibition |
| Anti-diuretic hormones (ADH)aka vasopressin | helps kidneys retain water to increase blood volume and pressure |
| what happens to urine levels for people who drink alcohol | dehydrate and use water |
| Oxytocin (OT) | initiates labor may facilitate sperm transport |
| Melatonin | circultaion rhythms and sleep, released at dark, timing of puberty, |
| Thyroxines | regulation of metabolic rate, requires iodine, |
| Calcitonin | encourages bone to store excess calcium, lowers blood calcium levels, decreases calcium reabsorption by the kidneys |
