Hormones Flashcards
Melatonin
Comes from pineal gland; controls season rhythms such as waking up
Hypothalamus hormone
Regulate the anterior pituitary secretion and sends hormones through the posterior pituitary
Posterior pituitary
Oxytocin & antidiuretic hormone (ADH)
Oxytocin
Stimulates contraction of uterus and milk “let down” reflex
Antidiuretic hormone (ADH)
Promotes retention of H2O by kidneys
Anterior pituitary
Growth hormone (GH), prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), thyroid stimulating hormone (TSH) adrenocorticotropic hormone (ACTH)
Growth hormone (GH)
Stimulates growth, most commonly in muscles and bones & regulates metabolism
Prolactin (PRL)
Stimulates milk production
Follicle-stimulating hormone (FSH)
Stimulates production of ova and sperm
Luteinizing hormone (LH)
Stimulates ovaries and testes
Thyroid stimulating hormone (TSH)
Stimulates thyroid gland
Adrenocorticotropic hormone (ACTH)
Simulates adrenal cortex to secrete glucocorticoids
Parathyroid hormone (PTH)
Raises blood calcium level
Thymosin
From thymus, programs T lymphocytes
Epinephrine and norepinephrine
From adrenal medulla; raises blood glucose level; increases metabolism; constrict certain blood vessels
Glucocorticoids
Cortisol: From adrenal cortex; increase blood glucose
Mineralocorticoids
Aldosterone: Promotes reabsorption of sodium and excretion of potassium and kidneys
Insulin
From the pancreas; reduces blood glucose
Glucagon
From the pancreas raises blood glucose
Androgens
From testes; support sperm formation; development and maintenance of secondary sex characteristics in males
Calcitonin
Reduces blood calcium level
Estrogens
Stimulate uterine lining growth; development and maintenance of secondary sex characteristics in females
Progesterone
Promotes growth of uterine lining
Thyroxine (t4) and triiodothyronine (t3)
Stimulates metabolism from thyroid
