Endocrine System Flashcards
Ecdysone
Hormone
Early development of insects
Endocrine gland
Ductless glands that secrete hormones
Brain hormone
Made in hypothalamus
Pheromones
Hormones that act between different organisms
Juvenile hormones
Inhibits ecdysone and prevents insects from maturing too quickly
Glucocorticoids
Steroid hormone
Regulates glucose level
Mineralcorticoids
Steroid hormones
Salt and water balance
Aldosterone
Thyroid gland
Growth development metabolic rate
Thyroxin
Secreted by thyroid
Oxygen consumption
Hypothyroidism
Not enough thyroid hormone is made
Hyperthyroidism
Too much thyroid hormone made
Calcitonin
Lowers calcium level
Parathyroid
Glands Located near thyroid
Secrete thyroid hormones
Estrogen
Female sex hormone
Amine
Neurotransmitter in plants and animal
cAMP
Second messenger
Mediates actions between hormones
Protein based hormones
Hydrophilic and not lipid soluble so have to bind to receptor proteins in cell membrane
Trigger secondary messenger
Lipid based hormones
Hydrophobic and lipid soluble so bind to receptor proteins in cytoplasm and nucleus
Transcription factors that turn on genes
Kinase cascade
Phosphate group transfers
G proteins
Second messengers activated by receptor proteins
Anterior pituitary
FSH LH ACTH growth hormone TSH prolactin
Growth, ect.
Posterior pituitary
Oxytocin vasopressin
Uterine contraction, kidney water absorption
Thyroid
Thyroid hormone calcitonin
Metabolic rate, lowers calcium level
Parathyroid
Parathyroid hormone
Increase blood calcium
Adrenal cortex
Alsosterone
Increases na and h2o reabsorption in kidneys
Adrenal medulla
Epinephrine nopinephrine
Increase blood glucose and heart rate
Pancreas
Insulin glucagon
Decrease blood sugar, increase sugar
Ovaries
Estrogen progesterone
Sex characteristics and endometrial lining
Testes
Testosterone
Sex characteristics and spermatogenesis
