ENDOCRINE GLANDS
Endocrine glands are glands of the endocrine system
that secrete their products, hormones, directly into the blood rather than
through a duct.
The main endocrine glands include the pituitary gland, pancreas, ovaries,
testes, thyroid gland,
and adrenal glands.
The
hypothalamus is a neuroendocrine organ. Other organs which are not so well
known for their endocrine activity include the stomach, which produces such
hormones as ghrelin.

THYROID
GLAND
-
The thyroid is one of the
largest endocrine glands in the
body. This gland is found in the neck
inferior of the
thyroid cartilage.
-
The thyroid controls how
quickly the body burns energy, makes proteins, and how sensitive the body
should be to other hormones
-
The thyroid gland is shaped
somewhat like a bow tie and is located in front of and slightly below the
larynx.
-
The thyroid participates in
these processes by producing thyroid hormones, principally thyroxine (T4)
and triiodothyroxine
(T3).
-
These hormones regulate the
rate of metabolism and affect the growth and rate of function of many
other systems in the body.
-
Iodine is an essential
component of both T4 and T3. The thyroid also produces the hormone
calcitonin,
which plays a role in
calcium homeostasis
-
It is non-iodinated thyroid
hormone which checks the concentration of Calcium and Sulphate
in blood plasma by decreasing metabolism from bones.
-
It’s deficiency results in
osteoporosis or loss of bone density
-
The thyroid is controlled by
hypothalamus and
pituitary.
