Histology lab exam 2

major endocrine glands

hypothalamus, pituitary gland, thyroid gland, adrenal gland, pancreatic islets, pineal gland, parathyroid gland,

secondary endocrine glands (organs)

heart, thymus, adipose tissue, digestive tract, kidneys, gonads, ovaries

what hormone does the hypothalamus secrete

ADH and OXT

Anterior lobe Pituitary gland secretes

ACTH, TSH, GH, PRL, FSH, LH and MSH

Posterior lobe pituitary gland secretes

OXT and ADH
IT DOES NOT PRODUCE THEM THOUGH

what is known as the master gland

pituitary gland

Thyroid gland secretes

T4, T3, and CT

adrenal glands two parts

Medulla and cortex

Adrenal Medulla gland secretes

epinephrine(fight flight) and norepinephrine(fight or flight)

Pancreatic Islets secrete

insulin and glucagon

pineal gland secretes

melatonin

Parathyroid gland secretes

Parathyroid hormone (increase calcium levels of blood)

Endocrine vs Exocrine

Endocrine are ductless and release hormones into bloodstream
