Endocrine system Flashcards
Anterior Pituitary
1 .Growth hormone - Stimulate bone and muscle
- Thyroid stimulating hormone
- Adrencorto tropic - Stimulate the adrenal cortex
- Follicle stimulating hormone - production of egg and sperm
- Lutenizing hormone - release of egg and sperm
- Prolactin - Stimulate milk production
Posterior pituitary
Oxytocin- releases milk from breast + bonding hormone
Antidiuretic- prevent water overload and dehydration
Thyroid
Thyroid Hormone
Calcitonin
BOTH ENERGY PRODUCTION
Parathyroid
Parathyroid Hormone -
Increases Ca2+
Adrenal cortex - LONG TERM STRESS RESPONSE
mineralcorticoids - INCREASE mineral content
Glucocorticoids- INCREASE glucose levels in the blood - this is the long term stress response -
Gonadcorticoids- sexual response
Adrenal Medulla - SHORT TERM STRESS RESPONSE
- Epinephrine
- NOR Epinephine
Pancreas
Glucagon -Incraese blood glucose
Insulin - decrease blood glucose
Ovaries
- estrogen
- progestrone
FEMALE REPRODUCTIVE HORMONES
Testies
Testosterone
Pineal gland
Melatonin -
body rythem
AUTOcrines
AUTOcrines - chemicals that exert their effects on the same cells that produce them
Paracrines-
Locally acting chemicles that affect cells other than those that secrete them
Hormones
Long distance acting chemicals
Regulate the metabloloc function of other cells
have lag times ranging from seconds to hours
Tend to have prolonged affects
Are classified as aminoacid based hormones or steriods
Eicosanoids
biologically active lipids with local hormones like activity
Target Cell Specificity
Hormones circulate to all tissues but only activate
cells referred to as target cells
▪ Target cells must have specific receptors to which
the hormone binds
▪ These receptors may be intracellular or located on
the plasma membrane
