hormones Flashcards
Follicle Stimulation Hormone (FSH)
Anterior lobe of pituitary
Responds to GnRH and LH
Responsible for
males: maturation and maintenance of male reproductive system and production of secondary sex characteristics
females: promotes egg maturation and signals secretion of estrogen and progesterone
Growth Hormone (GH)
Anterior Pituitary
Responsible for tissue building, influences nutrient metabolism, directly accelerates the rate of protein synthesis in skeletal muscles and bones, stimulates the production of BPG, contributes to lactation
Thyroid Stimulating Hormone (TSH)
Anterior Pituitary
Responds to thyrotropin releasing hormone from hypothalamus
Responsible for stimulating thyroid hormone release from thyroid
Lutenizing Hormone (LH)
Anterior Pituitary
Responsible for: the release of immature egg into uterine tube/ovulation, trigger production of ovarian hormone in females, and testosterone in males, stimulates androgen production by gonads
Adrenocorticotropic Hormone (ACTH)
Anterior Pituitary
Stimulates hormone release by adrenal cortex, heightens levels during pregnancy
Prolactin (PRL)
Anterior Pituitary
establishment and maintenance of breast milk supply raised during pregnancy
Gonadotropin-releasing Hormone (GnRH)
Hypothalamus
Responds to high levels of reproductive hormones, works as a negative feedback loop
Responsible for initiating puberty, stimulates anterior pituitary to secrete gondatotropins, stimulates the endocrine release off hormones, regulates production of FSH and LH
Corticotropin-releasing hormone
Hypothalamus
triggers release of ATCH
Glucagon
Alpha cells in pancreas
responsible for stimulating liver to begin glycogenolysis and take up amino acids to cover them into glucose, stimulates lipolysis, increase blood glucose
Oxytocin
Posterior pituitary
stimulates uterine contractions and dilation of the cervix, necessary for breastfeeding, plays a role in feeling attachment. Continually released during childbirth as a positive feedback system
Antidiuretic Hormone (ADH)
Hypothalamus, released by posterior pituitary
Responsible for: The amount of water reabsorbed from collecting ducts and tubules in kidneys
Parathyroid Hormone (PTH)
Parathyroid glands on posterior pituitary
Responsible for: regulating blood calcium levels
Melatonin
Pineal Gland
Responsible for body’s circadian rhythms, causes drowsiness
Calcitonin
Thyroid gland
stops the breakdown of bones by osteoclasts and stimulates calcium uptake in bones
responds to high blood calcium levels
insulin
Produced by beta cells
Responsible for uptake of glucose by body cells, stimulates store of glucose as glycogen in liver and muscle cells
