If a man looks carefully at the workmanship of God Almighty and the colors in the paintings of this world,
which has been created immensely, then the existence of man, in addition to
other living beings on this earth, also seem to be a question mark.
We will never be able to read the
creatures that live on this earth even if we want to, because after reading
them, our brain may give us the answer as to where this study started and where
it reached.
In the world of science, when the
scope of research has expanded and experts from different countries in
different periods of time have spent some time on the word curiosity in the
world of research, after studying human size and shape, the ancient secrets of
the human body are hidden. By writing about the structure and functions of all
these human organs in order to bring the facts to light, he attracted the whole
world and made himself the axis of the world of science.
As the human body is a masterpiece
of nature, it is also full of complexities where many minds cannot even think.
In all the organs of man today we
will study a very small structure hidden inside the human brain which in the
world of science is also called Pituitary Gland or according to some it is also
called Hypophysis.
This gland is located in the lower
part of our brain. This gland is located in the anterior inclination of the
bone surface called the sphenoid below the brain. It has two lobes at the front
and back in which the front is large and rectangular While the back is round.
It is the most famous and essential for the survival of our body. It produces
many types of hormones. Due to which it also affects the function of other
glands. Hence it is also called Master Gland.
If you look at its size, it measures
about one centimeter and weighs about 0.5 grams.
The bone in which it is embedded in
our brain is called Sella Turcica in scientific terms. This gland is connected
to another structure in the brain upwards which is commonly called Hypophysial
Stalk.
In terms of function, this pituitary
gland is divided into two distinct parts.
The anterior pituitary or
adenohypophysis or sometimes called the neurohypophysis.
Between the anterior part and the
posterior part there is a non-transmissible part called the Pars Intermedia,
which is the idea of gonadalists that this part Para Intermedia has no
specific structure and function in the human body but some It is considered to
be more and more important in living things.
When a human child is growing up in
the darkness of the womb, the formation of this gland also begins, in which two
parts of this pituitary gland appear from different types of sources or cells.
If we talk about the next pituitary,
it takes its existence from this special type of box or bag-like structure
known as Rathke's Pouch which comes into being from another structure called
Pharyngeal Epithelium during growth. Later, the posterior part of this gland,
the posterior pituitary part, also called the adenohypophysis, is made up of a
few neural tissues, a protruding structure of the hypothalamus.
If we look at the front of this
gland, we can see that it is derived from Epithelium and the same nature is
certainly similar to that of Epithelioid Cells, while if we look at the back of
the pituitary gland, it is called Neural Tissues or It is made up of nerve tissue,
so it is clear that our posterior pituitary is made up of the same special
cells Glial-Type that are present in this gland.
ANTERIOR PITUITARY
Interior pituitary
The anterior part of the pituitary
gland is large and rectangular. The hormones in this part are related to the
growth of the body and the reproductive organs. Its excess in small parts
produces gigantic gigantism. The deficiency of this hormone causes the body to stop
growing. If it occurs in childhood, then infatuation occurs. As a result, the
condition of a person remains the same as in childhood even in old age. It
releases the following hormones. ۔
1) GROWTH HORMONE
Growth hormone
Growth Hormone Growth Hormone
maintains the balance of growth in the body.
2) THYROTROPHIC HORMONE
Thyrotrophic hormones
Also called TSH, it stimulates the
adrenal glands to release hormones.
3) ADRENOCORTICOTROPHIC HORMONE
Adrenocortical Trophic Hormone
This hormone stimulates the adrenal
gland to release hormones.
4) LACTOGENIC HORMONE
Lactose intolerance
This hormone produces milk in the
breasts at the end of pregnancy.
5) GONADOTROPHIC HORMONE
Gonadotrophic hormone
This hormone forms the corpus luteum
inside the ovary in women. And in men, it causes the follicles to descend into
the scrotum.
6) Follicle Stimulating Hormone
(FSH)
FSH
It controls the maturation of
follicles in the ovaries in women and controls the production of sperm in men.
7) LUTEINIZING HORMONE
L-H
It changes the size of the ovary to
form corpus luteum and prepares it for breast milk. It is also called ICH
Interstitial-Cell Stimulating Hormone to control testosterone in men.
8) PROLACTIN HORMONE
Prolactin hormone
It is one of the many hormones that
help make breast milk.
9 POSTERIOR PITUITARY
Ter Pachutri
It releases two types of hormones.
1) OXYTOCIN HORMONE
A toxin hormone
It also powerfully stimulates the birth of the baby by helping the
contraction of the Birth Canal in women.
2) VASOPRESSIN HORMONE
Vasopressin
This hormone regulates the amount of water in our body and ensures
proper water retention.
