Endocrine System Flashcards
FSH
Peptide
Anterior Pituitary
Stimulates follicle maturation in females.
Stimulates spermatogenesis in males.
LH
Peptide
Anterior Pituitary
Stimulates ovulation in females.
Stimulates testosterone synthesis in males.
ACTH
Peptide
Anterior Pituitary
Stimulates adrenal cortex –> glucocorticoids
TSH
Peptide
Anterior Pituitary
Stimulates thyroid to produce thyroid hormones
Prolactin
Peptide
Anterior Pituitary
Stimulates milk production and secretion
Endorphins
Peptide
Anterior Pituitary
Decrease sensation of pain; can promote euphoria
GH
Peptide
Anterior Pituitary
Stimulates bone and muscle growth; raises blood glucose levels
ADH
Peptide
Posterior Pituitary
Stimulates water reabsorption by increasing permeability of collecting duct
Oxytocin
Peptide
Posterior Pituitary
Stimulates Uterine contractions during labor and milk secretion during lactation; may promote bonding behavior
T3 and T4
Amino Acid derivatives
Follicular cells
Stimulate metabolic activity
Calcitonin
Peptide
Parafollicular cells
Decreases blood calcium concentrations
PTH (parathyroid hormone)
Peptide
Parathyroid
Increases blood calcium concentrations
Glucocorticoids
i.e. cortisol and cortisone
Steroid
Adrenal Cortex
Increase blood glucose concentrations; decrease protein synthesis; anti-inflammatory
Mineralocorticoids
i.e. aldosterone
Steroid
Adrenal Cortex
Increase water reabsorption by increasing sodium reabsorption; promote potassium and hydrogen ion excretion
Epi and norepi
Amino Acid derivatives
Adrenal medulla
Increase blood glucose and heart rate; dilate bronchi; alter blood flow patterns
