The
Glands
The
following glands are the glands involved in the endocrine
system:
-Pituitary
Gland
-Tyroid
-Parathyroid
-Pineal Body*
-Adrenals
-Testes/Ovaries
-Pancreas
-Thymus
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.
FUN
FACT!
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.
