The Glands
The following glands are the glands involved in the endocrine system:
-​Pituitary Gland
​-Pineal Body*

 The Pituitary Gland:

The pituitary gland is considered the "master gland" of the endocrine system.  This is because it holds the ability to produce hormones that control various other glands throughout the system.  It produces endorphins, which are chemicals that act on the nervous system and decrease feelings of pain and discomfort in the body.  Additionally, the pituitary releases hormones that tell the reproductive glands to make sex hormones such as LH and FSH.

The pituitary gland is located in the lower brain beneath the hypothalamus.​​​​​
The pituitary gland is split into two sections:

The anetrior lobe and the posterior lobe.​​

​The Anterior Lobe
This part of the piuitary gland regulates the thyroid, adrenal glands, and reproductive glands (testes and ovaries).  It also produces hormones such as growth hormone, prolactin, thyrotropin, and corticotropin.

The Posterior Lobe​​
The​ posterior lobe of the pituitary releases antidiuretic hormone, which helps to control water balance in the body.  It also produces oxytocin, which is a hormone that makes the uterus contract in females during the birthing process.


​Did you know that the pituitary gland is no bigger than the size of a green pea?
The Thyroid:

The thyroid gland is located in the lower neck, closer to the front.  The thyroid gland's shape can be compared to that of a butterfly or a bowtie.  ​​
The release of thyroid hormones is controlled by thyrotropin (released by the pituitary gland).  The thyroid makes thyroxine and triiodothyronnie (what a mouthful! try eye doh thy ruh neen) which regulate the rate at which the cells burn fuels from food to make energy.  Additionally, the thyroid gland is partially responsible for the growth of kids' and teens' bone growth and development and the development of the brain in children.  It is also involved in the metabolism and body temperature
 ​The Parathyroids:
​The parathyroid glands​​ are the mini glands embedded in each side of the thyroid gland. They regulate calcium levels in the blood and bone metabolism by releasing parathyroid hormone.
