Anat_Hormones
The hormones produced by the endocrine system
Question | Answer |
---|---|
Epinephrine/Norepinephrine | Trigger cellular energy utilization and the mobilization of energy resources. Produced by the Adrenal Medulla. |
Aldosterone | Produced by Zona Glomerolosa. Targets kidney cells to regulate the ionic content of urine, causing the retention of water. Reduces losses at sweat glands, salivary glands and the digestive tract |
PTH | Parathyroid-hormone. Stimulates bones to release calcium, kidneys to decrease the excretion of calcium, also stimulates the release of vitamin D by the kidney to increase the intestinal absorption of calcium |
Calcitonin | Produced by the Thyroid gland. assists in the regulation of calcium ion concentration in the body fluids. It lowers calcium concentration by inhibiting osteoclasts and by stimulating calcium ion excretion from the kidneys |
T3 | Triiodothyrinine, active form of thyroid hormone which is about 10% of blood thyroid hormones |
T4 | Thyroxine, the inactive form of thyroid hormones and is 90% of the throid hormone sin the body |
MSH | Anterior Pituitary, Melanocyte-Stimulating Hormone, produced by the pars intermedia; increase the rate of melanin production in the skin; secreted in fetal development |
GH, HGH | Anterior Pituitary, Somatotrophin, stimulates cell growth and the replication by accelerating rate of protein synthesis (especially in skeletal and muscular systems) |
PRL | Anterior Pituitary, Prolactin, involved in the development of mammary glands and the production of milk; its function in males is not known |
LH | Anterior Pituitary, Lutenizing hormone, induces ovulation; releases of progestrins, release of androgens- "gonadotrophin" |
FSH | Anterior Pituitary, Follicle Stimulating Hormone, involved in the development of oocytes in ovaries, release of estrogens; sperm production- "gonadotrophin" |
ACTH | anterior pituitary, adrenocorticotropic hormone, releases adrenal cortex glucocorticoid steroid hormones (affect glucose metabolism) |
TSH | anterior pituitary, Thyroid Stimulating hormone, release thyroid hormones |
ADH | posterior pituitary, antidiuretic hormone or vasopressin, released in reponse to increased concentration of electrolytes in blood or fall in blood volume; acts to decrease water loss at kidney and constricts peripheral blood pressure |
Oxytocin | Posterior Pituitary, stimulates contractions of smooth muscle of uterus and contractile cells of mammary glands |
Humoral Stimuli | changes in the composition of the extracellular fluid |
Hormonal Stimuli | arrival or removal of specific hormone |
Neural stimuli | the arrival of neurotransmitters at neuroglandular junctions |
3 General Characteristics of Hormones | Stability, Communication, Distribution |
Water Soluble Hormone Types | Amino Acid Derivatives, Peptide Hormones, Protein Hormones |
Lipid Soluble Hormone Types | Steroid Hormones and Fatty Acid Derivatives |
