Endocrine System
Organs/parts
Hypothalamus
Control center of the brain
Thyroid
In the anterior neck
Increases metabolic rate
produces thyroid hormone
Thymus
Organ of the immune system
produces t cells
located in anterior thorax
Adrenal glands
Located superior to the kidney
Has medulla and cortex areas
A hormone secreting gland
Pancreas
Posterior to the stomach
Produces exocrine and endocrine secretions
Ovaries
Female sex organ
Ova are produced
Female gonad
coordinate control and regulate body functions
Testes
Male sex organ
Produces sperm
Pituitary gland
Endocrine glands
Growth hormone
Stimulates growth of cells
Stimulates epiphyseal plate growth
Thyroid hormone
Stimulates thyroid to release hormone
Adrenocorticotropic hormone
Stimulates the adrenal cortex
Gonadotrophin
follicle stimulating hormone
Luteinizing hormone
Thyroid hormone
increases metabolic rate
nutrients + oxygen to energy
Calcitonin
Produced by thyroid
Parathyroid hormone
Works on its own
Increases blood calcium level
Zona glomerulosa
secrete mineralocorticoids
Has kidneys retain sodium and water
Zona fasciculata
Secretes glucocorticoids
Maintains blood glucose level
Zona reticularis
secretes glucocorticoids and androgen
androgen is converted into testosterone and estrogen in other tissues
Terms: Glands, tissues and cells
Hormone
Chemical messenger
Travels in the blood

Parathyroid
Adrenal gland
Endocrine tissue
GI tract
Placenta
Kidneys
Skin
Pancreas
Gonads
Hypothalamus
Heart
Endocrine cells
Synthesize and secrete hormones
Target cells
Hormones effect these target cells
Bears the receptor for the hormone
Control of the hypothalamus
Anterior pituitary
True endocrine gland
Glandular tissue
Inhibits a release of hormone
Posterior pituitary
Stores hormones
oxytocin - stimulates contraction of the uterus
