Hormone Glands
Horomone glands are pituitary gland, thyroid gland, parathyroid glands, pancreas and others
Pituitary Gland is a hormone gland located at the base of brain just below the hypothalamous. Its function is to activate the other glands. It consisted of two portion: the Anterior lobe and posterior lobe.  There are many types of hormone functions:
1. Prolatin (PRL) Promotes milk production.
2. Follicle-stimulating hormone (FSH) is a glycoprotein called gonadotropins; regulates and stimulates both male and female gonads.
3. Luteinizing Hormone (LH) is similar to FSH, but it is essential for the release of egg cells from ovaries. 
4. Thyroid Stimulating hormone (TSH) is a glycoprotein that controls secretion of hormones from thyroid gland, and stimulates growht of the gland. High level of TSH may result of goiter.
5. Melacyte Stimulating Hormone (MSH) regulates pigment production.
6. Growth Hormone (GH), also called somatotrophin (STH), stimulates the growth of the size of the body.
7. Adrenocorticotropic Hormone (ACTH) is located above kidney, controls the production and secretion of certain hormones from adrenal cortex. It is also a fat metabolism.
Thyroid gland: Located below larynx, and surrounds trachea except its posterior. The thyroid plays major part of development and maturation of nervous system. It produces thyroxine and calcitonin hormone.

- Thyroxine: controlled by TSH from pituitary gland, and is essential for development and maturation of nervous syetem. It regulates the metabolism of carbohydrate, fat, and proteins. It contains four atom of iodine.
- Calcitonin: Synthesized by C-cell, regulates blood calcium and phosphate concentration.
Parathyroid Glands: are four dots located posterior of thyroid gland, and lateral to trachea. Their functions are to secrete a hormone, called Parothyroid Hormone (PTH), which regulates Target three known tissues of PTH.

- Intestines: PTH absorption of calcium, cause high calcium in blood. Low calcium causes convulsion and possible death calcitonin (thyroid decreases calcium.
- Kidneys: PTH inhibits secretion of calcium from the body.
- Bone: PTH increases activity of Osteoblasts, which dissolve Calcium phosphate, causing increase of calcium in blood.
Pancreas: is an endocrine and exocirne gland. It consists of Alpha cells and Beta cells.

-Alpha Cells: Produced glucogon, which increases blood glucose.
-Beta Cells: Produced Insulin which decreases blood glucose.

Glucose level Control:
High Level - Pancrea secretes insulin, causing liver converts glucose to glycogen, then stored in liver. 
Low Level- Panceas secrete glucogon, causing liver converts glycogen to glucose.
Ovaries: Produced estogen and progesterone for female.
Testis: Produced testoterone for the males.
Thymus: Located superior of heart. Its function is to produce thymosin which affects T-lymphacyte differentation and development. Thymus is only present up to pubesty.
