Nervous and Endocrine Flashcards
growth hormone
where does it come from?
What does it do?
what type of molecule is it?
anterior pituitary
increases bone and muscle growth by increasing cell turnover rate
growth hormone is a peptide molecule
prolactin
where does it come from?
What does it do?
what type of molecule is it?
prolactin comes from the anterior pituitary
prolactin stimulates milk production
prolactin is a peptide
Thyroid stimulating hormone TSH
where does it come from?
What does it do?
what type of molecule is it?
TSH is produced by the anterior pituitary
TSH increases the production and release of thyroid hormone from the thyroid
TSH is a peptide hormone
adrenocorticotropic hormone ACTH
where does it come from?
What does it do?
what type of molecule is it?
ACTH stimlates release of cortisol and aldosterone from the adrenal cortex
ACTH is released from the anterior pituitary
ACTH is a peptide hormone
Luteinizing hormone LH
where does it come from?
What does it do?
what type of molecule is it?
LH is producec by adenohypophysis
stimulates testosterone production in males, ovulation in females, maintenance of the corpus luteum
FSH follicle stimulating hormone
where does it come from?
What does it do?
what type of molecule is it?
stimulates ovary/follicle development in females. FSH stimulates spermatogenesis in males
made in A.P.
FSH is a peptide
vasopressin/ADH
where does it come from?
What does it do?
what type of molecule is it?
ADH made in neurohypophysis (post. pit.)
ADH promotes water permeability in the Distal convoluted tubule of the nephron. this allows water to be reabsorbed from the filtrate. ADH secretion from the Post-Pit. is stimulated by low blood pressure or dehydration
ADH is a peptide.
oxytocin
where does it come from?
What does it do?
what type of molecule is it?
oxytocin is released from the posterior pituitary.
it stimulates milk let down and production. also stimulates uterine contraction
thyroid hormone (TH, thyroxine) where does it come from? What does it do? what type of molecule is it?
produced and released from thyroid
its necessary for the mental and physical development of children. TH affects temperature and metabolic rate in adults
thyroid is a modified amino acid
calcitonin
where does it come from?
What does it do?
what type of molecule is it?
calcitonin is made and released from the thyroid C cells.
calcitonin lowers serum calcium concentrations
calcitonin is a peptide hormone
parathyroid hormone PTH
where does it come from?
What does it do?
what type of molecule is it?
PTH raises serum calcium levels
released from parathyroid
its a peptide hromone
thymosin
where does it come from?
What does it do?
what type of molecule is it?
released from thymus only in children.
thymosin directs T cell development
peptide
what hormones are released from the adrenal medulla and cortex?
medulla: epinepherine
cortex: cortisol, sex steroids, aldosterone
what does aldosterone do?
what kind of hormone
increases reabsorption of sodium
aldosterone is a mineralocorticoid steroid hormone
what kind of hormone is cortisol?
glucocorticoid (steroid)
