Endocrine Glands

The endocrine glands secrete hormones directly into the blood

~ Small Part of the brain ~ hormones influence activity of the Pituitary gland

~ Back of the Thyroid ~ Secretes Parathormone ~ Controls Calcium metabolism

~ secretes Thyroxin ~ Located in neck ~ Regulates rate of metabolism and is essential for normal (physical and mental) development

~ The male and Female reproduction organs ~Ovaries and Testes

~ Located at top of each kidney ~ Outer layer is called Adrenal Cortex ~ Inner layer is called Adrenal Medulla ~ Secretes Adrenaline ~ Increases Blood Glucose level and accelerates the rates or heartbeat and Breathing ~ Releases hormone in state of stress and heavy exercise

~ Located at the base of the brain ~ Many hormones are secreted ~ Regulates activities of other endocrine glands

~ Pituitary Hormone ~ Widespread of effects in the body ~ Stimulates growth of long bones

~ Pituitary Hormone ~ Stimulates the secretion of Thyroxin

~ Small groupps found throughout the Pancreas ~ Secretes Insulin and Glucagen

~ Promotes the absorbtion of Glucagen ~ Lowers blood glucose level

~ Increases blood glucose level ~ Promotes the conversion of glycogen to glucose in the liver and skeletal muscle

~ Secretes female sex hormone called Estrogen ~ Estrogen develops the female sex organs, stimulates the production of egg cells and influences the development of female secondary sex characters

~ Secretes male sex hormone called Testosterone ~ Testosterone stimulates the development of male reproductive organs, and secondary characteristics ~ Stimulates production of sperm cells

~ FSH ~ Pituitary Hormone ~ stimulates the development of follicles in the ovaries (for females) and influences sperm production (for males)

~ mechanism that regulates the secretion of hormones by the endocrine glands.

~ An Enlargement of the thyroid gland that is most commonly caused by a lack of iodine

Disorder in which the islets of Langerhans do not secrete an adequate amount of insulin and the blood glucose level is elevated/.
