Term
What is PTH?
Definition
Parathyroid Hormone - Protein - Formed from Amino Acids
Term
Where is PTH located?
Definition
Posterior surface of the Thyroid Gland
Term
What does PTH do?
Definition
Secretes a hormone that regulates the concentrations of calcium & phosphate ions in the blood.
Term
What are the hormones in the Adrenal Medulla?
Definition
Epinephrine - Norepenephrine
Term
What does Epinephrine & Norepinephrine do(Adrenal Medulla hormones)?
Definition
Stimulate their effectors - Increased heart rate, force of cardiac muscle contraction, elevated blood pressure, increased breather rate, & decreased digestive activity.
Term
What is Aldosterone?
Definition
Steroid Hormone from the Adrenal Gland
Term
What does Aldosterone do?
Definition
Stimulate sodium retention by the kidneys.
Term
What is Negative Feedback?
Definition
Control of hormone secretion. The endocrine gland or the system controlling it senses the concentration of the hormone the gland secretes, a process the hormone controls, or an action the hormone has on the internal environment.
Term
How is Negative Feedback regulated?
Definition
when the concentration of a substance it regulates reaches a certain concentration it inhibits the gland.
Term
What are the hermones in the Posterior Pituitary?
Definition
Antidiuretic Hormone (ADH) - Oxytocin (OT)
Term
What does the Antidiuretic Hormone (ADH) do (Posterior Pituitary)?
Definition
Constricts blood vessel walls, raising blood pressure.
Term
What does the Oxytocin (OT) hormone do (Posterior Pituitary)?
Definition
Has an antidiuretic effect & can contract muscles in the uterine wall. Contracts certain cells associated with production & ejection of mil from the milk glands of the breast.
Term
What does Growth Hormone do?
Definition
Stimulates body cells to grow & divide. Releasing hormone & somatostatin from the hypothalamus control GH secretion.
Term
What are the stress hermones?
Definition
Epinephrine, cortisol, ACTH, glucagon, growth hormone, antidiuretic, renin
Term
What is the effect of stress hermones on hemeostasis?
Definition
Increased activity of the sympathetic nervous system & increased secretion of adrenal hormones.
Term
What is insulin?
Definition
A protein.
Term
What does insulin do?
Definition
Stimulates the liver to form glucagon from glucose & inhibites conversion of noncarbohydrates into glucose.
Term
What are the hormones in the Anterior Pituitary?
Definition
Growth Hormone, Prolactin, TSH, ACTH, FSH, LH
Term
What are the steroid hormones?
Definition
Aldosterone, cortisol, testerone, estiriol
Term
How are the steroid hermones regulated?
Definition
Insoluble in water. Carried int he bloodstream weakly bound to plasma proteins.
Term
What are the amine hormones
Definition
Norepinephrine & Epinephrine
Term
What are the peptide hormones?
Definition
Antidiuretic & Oxytocin
Term
How does ADH & Oxytocin function?
Definition
ADH causes the kidney to excrete less water. Oxytocin has an antidiuretic effect and can contract muscles in the uterine wall.
Term
What is the characteristic of red blood cell.
Definition
Erythrocytes - tiny. biconcaved disc.
