Secretion of Hormones Flashcards
Oxytocin
by Posterior Pituitary
in response to Childbirth
Vasopressin (ADH)
by Posterior Pituitary
in response to High Plasma Osmolality
FSH
by Anterior Pituitary
in response to GnRH
LH
by Anterior Pituitary
in response to GnRH; estrogen spike from follicle just before ovulation
ACTH
by Anterior Pituitary
in response to CRH, stress
TSH
by Anterior Pituitary
in response to TRH, low plasma levels of T3 and T4
Prolactin
by Anterior Pituitary
in response to Falling progesterone at end of pregnancy
Endorphin
by Anterior Pituitary
in response to Pain
Growth hormone
by Anterior Pituitary
in response to GHRH
Calcitonin
by Thyroid
in response to High plasma [Ca2+]
T4 and T3
by Thyroid
in response to TSH
Parathyroid hormone
by Parathyroid
in response to Low Plasma [Ca2+]
Glucagon
by Pancreatic alpha cells
in response to Low Blood [Glucose]
Insulin
by Pancreatic beta cells
in response to High Blood [Glucose]
Somatostatin
by Pancreatic delta cells
in response to Varies –> usually high hormone levels
Cortisol
by Adrenal Cortex
in response to Stress
Aldosterone
by Adrenal Cortex
in response to ACTH, Angiotensin II, Low BP
Epinephrine
by Adrenal Medulla
in response to Sudden Stress
Estrogen
Female: Ovaries
Male: Adrenal
in response to FSH
Progesterone
Female: Ovary, corpus luteum
Male: Adrenal
in response to Ovulation
Testosterone
Female: Ovaries
Male: Leydig cells of testes
in response to GnRH –> LH –> testosterone
