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 |
