Cards

Term
hypothalamus
Definition
Secretes releasing and inhibiting hormones that control anterior pituitary gland • Produces hormones that are transported to and stored in posterior pituitary gland
Term
anterior pituitary gland
Definition
Synthesizes and secretes: thyroid-stimulating hormone (TSH), prolactin (PRL), adrenocorticotropic hormone (ACTH), growth hormone (GH), luteinizing hormone (LH), melanocyte-stimulating hormone (MSH), and follicle-stimulating hormone (FSH)
Term
Posterior pituitary
Definition
Secretes oxytocin and antidiuretic hormone (i.e., ADH or vasopressin); these hormones (synthesized by hypothalamic cells) are transported to posterior pituitary for storage (visible as Herring bodies) and eventually released into capillaries • Pituicytes support hypothalamic axons
Term
Thyroid gland/ para thy
Definition
Follicular cells: synthesize and secrete thyroid hormones T3 (triiodothyronine) and T4 (thyroxine) • Parafollicular cells: synthesize and secrete calcitonin
Term
ovary
Definition
Produces the female sex hormones progesterone, estrogen, and inhibin
Term
testis
Definition
Produces androgens (male sex hormones) such as testosterone
Term
Zona fasciculata
Definition
Produces glucocorticoids (e.g., cortisol) that stimulate lipid and protein metabolism, and regulate blood glucose levels
Term
Zona glomerulosa
Definition
Produces mineralocorticoids, especially aldosterone
Term
Zona reticularis
Definition
Produces sex hormones, chiefly androgens
Term
adrenal medulla
Definition
Produces epinephrine (adrenaline) and norepinephrine (noradrenaline) that work with sympathetic nervous system in "fight-or-flight" responses
Term
adrenal cortex
Definition
Zonula glomerulosa produces mineralocorticoids (e.g., aldosterone) that regulate sodium/potassium ratio in blood and body fluids • Zonula fasciculata produces glucocorticoids (e.g., cortisol) that stimulate lipid and protein metabolism, and regulate blood glucose levels • Zonula reticularis produces steroid sex hormones called gonadocorticoids (e.g., dehydroepiandrosterone or DHEA)
Term
a cells
Definition
• Secretes hormone glucagon
Term
beta cells
Definition
Secretes hormone insulin
Term
delta cells
Definition
somatostatin
Term
F cells(PP cells) are pancreatic polypeptide producing cells
