| Question | Answer |
|---|---|
| specialized chemical produced and secreted by and endocrine cell or tissue. Travels through blood stream and only effective in target areas. | Hormone |
| hormone secreting cells | endocrine organs |
| Secrete product into interstitial fluid surrounding secretory cells | endocrine glands |
| Integrating link b/n endocrine and nervous system | Hypothalamus |
| acts intercellularly to modify protein synthesis | steroids |
| acts on cell membrane | amine/amino acid derivatives |
| vassopressin, insulin, growth hormone, andrenocorticotropic hormone | Protein/Peptide hormone |
| Master endocrine gland | Pituitary gland(hypophysis) |
| Secretes hormones that regulate a wide range of bodily activities from growth to reproduction | Anterior pituitary (adenohypophysis) |
| Acts primarily on bones and muscles. Stimulates the growth of the bone and in the muscles. | GH or somatotropin |
| Condition where pituitary does not secret | hypopituitarism |
| hyposecretion of growth hormone leads to | stunted growth |
| Stimulates secretion of prolactin for milk production, growth of breast | Prolactin releasing hormone |
| Secreted at the end of pregnancy (3rd trimester) and acts on mammary gland | Prolactin |
| regulates the ecdocrine activity of the cortex portion of the adrenal gland | Adrenocorticotropic hormone |
| Influences the growth and activity of the gonads. Stimulates production and secretion of thyroid hormones | thyroid stimulating hormone(TSH) or Thyrotropic hormone(TH) |
| Regulates hormonal activity of the gonads. | Gonadotropic hormone |
| stimulates follicle development in the ovaries for female. Stimulates sperm development by the testes in male | Follicle stimulating hormone(FSH) |
| triggers ovulation of an egg from the female's ovary. In males, referred as interstitial cell stimulating hormone(ICSH) | Luteinizing Hormone |
| Storage area by the hypothalamus; hypothalamic neurons | posterior pituitary(neurohypophysis) |
| Helps regulate the body's fluid balance. Maintains proper water balance. effect on raising blood pressure. | Antidiuretic hormone(ADH)(vasopressin) |
| Bridge that connects the 2 lobes of thyroid gland | Isthmus |
