HORMONE (COORDINATION RESPONSE) Flashcards
What are the hormones in posterior lobe of pituitary gland?
Antidiuretic (ADH) and Oxytocin
State the organ/target tissue and function of ADH
-kidney tubule
stimulates reabsorption of water
organ and functions of oxytocin
uterine muscles-stimulates contraction of uterine muscle during birth
mammary gland-stimulates production of milk from mammary gland
What are the hormones in anterior lobe of pituitary gland?
LH (luteinizing hormone) GH (growth hormone) ACTH (adrenocorticoprotic) TSH (thyroid-stimulating hormone) FSH (follicle-stimulating hormone)
LH (luteinizing hormone)
*ovary/testis
stimulates ovulation
development of corpus luteum
secretion of oestrogen+progesterone
GH (growth hormone)
*soft tissue bone
stimulates growth
protein synthesis
fat metabolism
ACTH (adrenocorticoprotic) hormone
*adrenal cortex
stimulates adrenal cortex to secrete hormone
TSH (thyroid-stimulating hormone)
*thyroid gland
stimulates thyroid gland to secrete thyroxin
FSH (follicle-stimulating hormone)
*ovary/testis
stimulates development of follicle growth
stimulates spermatogenesis
What are the main organs involved in hormone secretion?
thyroid gland adrenal gland pancreas ovary testis
thyroid gland (hormone,target tissues functions)
throxin all increase metabolism rate increase body temperature increase growth and development
adrenal gland
aldosterone
kidney
increase level of sugar and fatty acids in blood
increase respiratory rate and heartbeat
pancreas
hormone:insulin and glucagon
target tissues:liver-muscle-adipose tissue
insulin hormone
to decrease blood sugar level
promotes conversion of excess glucose to glycogen
glucagon hormone
to increase blood sugar level
conversion of glycogen to glucose
ovary
hormone:oestrogen and progesterone
oestrogen
*gonad-skin-muscle-bone
stimulates follicle growth
stimulates thickening of uterus
progesterone
*gonad
stimulates formation of placenta
stimulates development of uterus wall
testis
*testosterone
gonad-skin-muscle-bone
stimulates development of secondary sexual characteristics in male
-spermatogenesis
What are the health issues related to hormone
Diabetes mellitus Diabetes insipidus Hypothyroidism Hyperthyroidism Gigantism Dwarfism
DIABETES MELLITUS
cannot produce insulin
blood glucose level is high
symptom of diabetes mellitus
urinate frequently
always feel thirsty
numbness at sole of feet
blurred vision
hypoglycaemia
blood glucose level is low
symptom-fatigue-difficulties to sleep at night-headache
DIABETES INSIPIDUS
posterior lobe of pituitary gland cannot secrete (ADH)
symptoms of diabetes insipidus
produce large amount of urine-often feel thirtsy-experience dehydration
HYPOTHYROIDISM
inadequate thyroxin secretion
symptoms of hypothyroidism
slow heartbeat
extremely sensitive to cold
gain weight easily
HYPERTHYROIDISM
too much thyroxine is secreted
symptoms of hyperthyroidism
excessive sweating-heat intolerance
GIGANTISM
excessive secretion of GH
symptoms of gigantism
abnormal elongation of bones
extremely tall
DWARFISM
low secretion of GH
symptoms of dwarfism
delay growth of bones
