Endocrine System OverviewEndocrine System Overview

Network of ductless glands and other structures

Glands secrete hormones which affect function of targeted organs


adrenal glands located next to each kidney

adrenal cortex (outer part of the gland) secretes steroid hormones which regulate carbohydrate metabolism and salt and water balance

adrenal medulla (inner portion of the gland)

secretes epinephrine and norepinephrine (fight or flight

(responses)

(continued)(continued)


steroid hormones regulate carbohydrate metabolism and salt and water balance

(continued)(continued)


ovaries located one on each side of the uterus

secretes estrogen — Responsible for development of female secondary sex characteristics and regulation of reproduction

Progesterone--hormone of pregnancy


pancreas (islets of Langerhans) located behind the stomach

functions to secrete insulin (in presence of bl. glucose) and glucagon (in the absence of bl. glucose)

parathyroid glands located on the posterior aspect of the thyroid gland in the neck

functions to secrete parathyroid hormone (PTH) Responsible for maintaining Calcium and phosphorus

levels in the blood.


pineal gland Located in the center of the brain

Secretes melatonin (sleep/wake cycles) and serotonin


pituitary gland Anterior pituitary gland (adenohypophysis)

Located at the base of the brain

Secretes thyroid-stimulating hormone, adrenocorticotrophic hormone, follicle-stimulating hormone, luteinizing hormone, melanocyte-stimulating hormone, growth hormone and prolactin

posterior pituitary (neurohypophysis) Releases antidiuretic hormone and oxytocin

Hyperthyroidism and Hyperthyroidism and HypothyroidismHypothyroidism


testes located one on each side within the scrotum in the male

functions to secrete testosterone

thymus gland located in the mediastinal cavity anterior to and above the heart

functions to secrete thymosin


thyroid gland located in the front of the neck

secretes triiodothyronine, thyroxine and calcitonin
