| Question | Answer |
|---|---|
| what is the intrernal secretion of hormones directly into the bloodtream to reach target cells helps regulate metabolism | Endrocrine ( into Blood) |
| what is secreation of product out of the area?IE: acid in GI or Sweat | exocrine ( exiting area) |
| chemistry of Hormones 2 types: | non- steroids & steroids |
| What are Chemical messengers | Hormones |
| What are Amino Acid compounds called? | Non -Steroids Hormones |
| what are lipid based hormone derived from cholesterol (dosn't disoves in lipids) called? | Steroids Hormones |
| Non- Steroids1. Amines | derives from amino acid tyrosine-epinephrine & norepinephrine ( adrenaline and noradrenaline) |
| Non- Steroids2. Protein | composed of long chains of amino acidsparathyroid hormone, Growth Hormone and Prolactin |
| Non- Steroids 3. Glycoproteins | proteins joined to carbohydrates, FSH follicle stimulation hormoneLH luteinizing HormoneTSH thyroid stimulation Hormone |
| Non- Steroids4. Peptide | Short chains of amino acidsADH Antidiuretic HormoneOT Oxytocin HormoneTRH Thyrotropin Releasing HormoneSS SomatostatinGnRH Gonadotropin Releasing |
| Non- Steroids5. Prostaglandins | Fatty acids produced in a wide variety of cells |
| Steroids | Lipid base derived fron cholesterol ( dissolves in lipids) |
| Steroids has 2 hormones what are they? | 1. Sex Hormones 2. Adrenal cortex secretions |
| What are the 2 Sex Hormones Called? | 1. Testosterone2. Estrogen |
| What are the two Adrenal Cortex Secretion called? | 1.Aldosterone 2. Cortisol |
| What are Target Cells? | cells that the hormone will be acting upon |
| What hormone does the Pineal secreat? | Melatonin |
| what Action does the Pineal Gland have? | its your Sleep & Wake cycleLight & dark cycles |
| Hypothalamus gland | Tropic Hormones that regulate other Hormones |
| Pituitary Gland Posterior Lobe 2 Hormones | 1. Oxytocin2. Antidiuretic |
| Oxytocin creates what type of Action? | Uterine contraction & milk let down |
| What type of Action does the antidiuretic Hormone produce? | Water retention |
| Thyroid Gland has what 2 Harmones? | 1. Thyroxine ( T4)2. Triiiodothyroxine (T3)2.Calcitonin |
| What action does T3 & T4 produce and regulate? | stimulates Metabolisimand regulates TSH |
| Parathyroid gland | Parathyroid hormone( PTH) |
| What type of Action does the Parathyroid hormone cause? | Raises blood Calcium levels |
| What type of Action from the calcitonin hormone produce? | Decreases the Blood Calcium levels |
| what type of Hormone does the Thymus gland have? | Thymosin Hormone |
| what are the 2 adenal Glands called? | 1. Adrenal Medulla2. Adrenal cortex |
| the Adrenal Medulla has 4 Homones called what? | 1. Epinephrine2. Norepinephrine3. Adrenaline4. Noradrenalinethe Flight or fight response |
| What type of action does the Adrenal Medula gland produce? | Raises blood glucose increases rate of medtabolism constrict certain blood vessels |
| what are the names of the three hormones from the Adrenal Cortex? | 1.Glucocorticoids also known as Cortisol2. Mineralocaorticoids also know as Aldosterones3. Sex Hormones also know as adrenal androgens |
| What happens with the cortisol hormone? | 1. aids in metabolism of carbohydrates,proteins,and fats2. active during stress by increasing the levels of nutrients in the blood3. supresses the inflamatory response |
| Aldosterone or mieralocorticoid its action | aids in regulating K & Na and water balancepromotes reabsorbtion of sodium and potasium in kidneys |
| what's the Action in the adrenal androgens hormone? | progestrons and estrogen |
| Pancreatic islets has 3 hormones: | 1.Insulin 2. Glucagon 3. Somatostatin |
| what type of cell does Insulin have? | beta cell |
| what type of cell does the glucagon have? | alpha cell |
| what type of cell does the somatostatin have? | Delta cell |
| what happens to glucose when insulin is introduced to the body? | Reduces blood glucose |
| what happens to glucose when Glucagon is in the blood? | raises the blood glucose stimulated by liver |
| what does the Somatostatin hormone do in the blood? | Inhibits secretions of Glucagons and insulin in blood. |
| Anterior Pituitary Lobe has 6 hormones | 1. GH Growth Hormone2. PRL Prolactin ( stimulates milk production)3. FSH follicle stmulating Hormone4. LH Luteninizing Hormone 5. TSH Thyroid stimulating hormone6. ACTH AdrenoCorticoTropic Hormone |
| ACTH Adrenacorticotropic hormone does what action? | Stimulates the Adrenal Cortex to secrete glucocorticoids ( cortisol) |
