Chapter 11 : Endocrine System (Gland+Hormone) Flashcards
Anterior Pituitary Gland Hormones
Growth Hormone Thyroid - Stimulating Hormone Adrenocorticotropic Hormone Follicle - stimulating Hormone Luteinizing Hormone Prolactin
Growth Hormone Target cells
Targets most body tissues such as bone and muscle
Growth Hormone Action
Stimulates growth
Thyroid - Stimulating Hormone
Target Cells
Thyroid Gland
Thyroid - Stimulating Hormone
Action
Increases thyroxine production
Adrenocorticotropic Hormone
Target Cells
Cortex of adrenal gland
Adrenocorticotropic Hormone
Action
Increases the secretion of glucocorticoids
Follicle - Stimulating Hormone
Target Cells
Ovarian follicles of females, seminiferous tubules of males
Follicle - Stimulating Hormone
Action
Stimulates follicle growth and estrogen secretion in females, spermatogenesis in males
Luteinizing Hormone
Target cells
Ovaries in females or interstitial cells of testes in males
Luteinizing Hormone
Action
Promotes ovulation and progesterone secretion in females and promotes testosterone secretion in males
Prolactin
Target cells
Mammary glands in females
Prolactin
Action
Stimulates milk production
Posterior Pituitary Gland
Antidiuretic hormone
Oxytocin
Antidiuretic hormone
Target cells
Kidneys
Antidiuretic hormone
Action
Decrease water loss to urine
Oxytocin
Target cells
uterus and mammary glands
Oxytocin
Action
Increases uterine contractions during menstruation and child birth and stimulates milk ejection
Thyroxine and Triiodothryonine
Target cells
Most body cells
Thyroxine and Triiodothryonine
Action
Regulates metabolic rate
increases the rate of energy release, protein synthesis, growth, and nervous system activity
Calcitonin
Target cells
Osteocytes (bone cells)
Calcitonin
Action
Inhibits bone breakdown by osteoclasts when blood calcium levels are high
Parathyroid Hormone
Target cells
Bone
Kidney
Digestive tract
Parathyroid Hormone
in bones
Increases osteoclast activity (bone breakdown)
Parathyroid Hormone
in Kidneys
Decrease Calcium loss to urine
Parathyroid Hormone
in the intestines
Increases vitamin D usage and absorption of calcium from diet
