The Endocrine Glands Also includes organs from other systems that produce hormones Examples:

The Endocrine Glands

Produces hormones that act on the pituitary Hypothalmus Part of the brain Produces hormones that act on the pituitary Releasing hormones Example: Inhibiting hormones

Pituitary Gland “Master gland” that controls many of the other glands Two parts: Anterior and posterior Hormones: Growth hormone Thyroid-stimulating hormone Adrenocorticotropic hormone Endorphins Antidiuretic hormone FSH, LH (reproductive)

Growth hormone Controls cell division, protein synthesis and bone growth in children and adolescents Problems can lead to dwarfism or giantism

Thyroid and Parathyroid Found in the front of the throat Hormones: Thyroxine: Calcitonin: Parathyroid hormone (PTH):

Thyroid and Parathyroid Thyroxine: Contains 4 iodine atoms Lack of iodine in diet, causes this hormone to be overproduced and to build up in the thyroid Disorder called goiter

Thyroid and parathyroid Important for the control of calcium levels Calcium is found in the: Bone Important for? Blood

Control of calcium levels

Adrenal Gland Located on the kidneys Hormones: Epinephrine and Norepinephrine: Aldosterone: Cortisol:
