Questions- Chemical Coordination and Integration Video Lecture - NEET

to friends this video on chemical
coordination and integration part 19 is
brought to you by exam fire comm no more
fear from exam now it is time to look at
some of the questions so I hope that
this lesson would have helped you
because I am NOT going to take up all
the questions because most of them have
already been answered by I was teaching
the lesson so let us look at some of the
questions here question number one list
the hormones secreted by the following
hypothalamus so what are the hormones
secreted by hypothalamus so if you talk
about hypothalamus they secrete two
types of hormones one is the releasing
hormones that is the hornwood so the
hormone sectors are secreted by
hypothalamus are the releasing hormones
and that inhibiting hormones right so
what do we do the releasing hormones
actually tell the pituitary to release
the pituitary hormones similarly the
inhibiting hormones actually tell the
pituitary to stop releasing any more
hormones so these are the two types of
hormones which are secreted by the
hypothalamus next is the pituitary
pituitary the master gland so it
secretes a lot of hormones so that these
organs in turn can control the other
glands of the body so some of the
hormones secreted by the pituitary are
the growth hormone the luteinizing
hormone the thyroid stimulating hormone
follicle-stimulating hormone ACTH that
is adrenocorticotropic hormone prolactin
so these are the hormones which are
secreted by the pituitary so mostly the
most of them are secreted by the
anterior pituitary other than this the
posterior pituitary also separates the
oxytocin and vasopressin next is the
thyroid the thyroid secretes the
thyroxine that is T 3 T 4 T C T that is
kind of calcitonin
parathyroid so parathyroid secretes para
hormone which is often written as
II pth or or that you can read it in an
apartment because not many people are
aware of the short forms of many of the
hormones next is the adrenal no adrenal
again that renal medulla secretes the
adrenaline noradrenaline adrenaline and
noradrenaline
these are secreted by the adrenal
medulla and what about the adrenal
cortex it secretes the cornichons and
aquatic ecology we can have so many
times if you go cortical it's
mineralocorticoids etc pancreas in
pancreas we talk about the islets of
langerhans and it leads to very
important hormones that is insulin and
glucagon
next is the testes testes secretes the
male intrusion that is the testosterone
ovary which secretes the female hormones
that is the estrogen and the
progesterone estrogen and progesterone
so estrogen takes care of all the female
sex organs on the female behaviors the
female secondary sexual character and
progesterone takes care of things
related to pregnancy thymus gland so it
releases the whole book on thymosin
which builds up the immune system act
reom what does it release add three of
the reasons that our tree and that tree
Heretic factor which is also known as a
and F in short form that is act real man
tree you read thick factor of a what a
and F
kidney so what does the give me secrets
it secretes any throat poison so adding
through point in is it treated like
kidney and the GI tract that is the
gastrointestinal tract
a lot of hormones like the gas stream
the secret in the CCK that is the
cholecystokinin so these are some of the
volvo secreted by the gastrointestinal
tract let us look at the next question
fill in the blanks hormones target gland
so now you have to tell which are the
target glands for these hormones so
hypothalamic hormone so hypothalamic
hormones control which gland pituitary
gland so their target gland and is going
to me with children
next is the thyrotropin or TSH thyroid
stimulating hormone thyroid robbing is
just another name for TSH so which is
the target land it is secreted by the
pituitary but it targets the thyroid
gland because it it wants to control the
secretion of the thyroid hormones from
the thyroid gland corticotropin that is
my Drano corticotropin hormone which is
again secreted by the pituitary and
which is the target gland the target
gland is the adrenal cortex so adrenal
cortex is going to be the target cloud
because it will target this land so that
it can regulate the secretion of
hormones from this gland gonadotropins
so Ferrando drop-ins what does it do so
gonadotropins well actually this LH and
FSH so their target organs are going to
be the ovaries and testes so that it can
regulate the secretion of testosterone
progesterone and estrogen from these
orphans Milano drop in the target gland
is going to be the pineal gland and
therefore it that is how it will
regulate the secretion of the melanin
team from the pineal gland
let us look at question number 3 give
examples of high
like semicolon and hypoglycemic hormones
so hyper means more glycemic that is
more glucose so whenever you say more
glucose in the glove like that means the
organ which increases the level of
glucose in blood and that is glucagon
and just the opposite of glucagon is
hypoglycemic which is nothing but
insulin hypercalcemia hormone a hormone
which increases the level of calcium in
the blood
what does that hormone it is
parathormone which is secreted by the
parathyroid gland
gonadotropic hormones that is those
which actually stimulates the gonadal
activity like that LH luteinizing
hormone and qualified stimulating
hormone purchased a tional hormone so
this hormone is the one which supports
during pregnancy and that is
progesterone blood pressure lowering
organs the which almond lowers the blood
pressure this is very important this is
non adrenaline which is released by the
adrenal medulla androgens and estrogens
so examples of androgen would be the
testosterone testosterone of course is
an example of androgen astrojet example
of this trojan would be is tried ion so
these are examples of all these hormones
question number four which hormone
deficiency is responsible for the
following
diabetes mellitus as i have mentioned
before also deficiency of what will
cause increase of glucose level in the
blood insulin so the efficiency of
insulin will cause diabetes vital will
be caused due to deficiency of iodine so
I will being impact which Harun it
impacts the
I am for rules so you can say that I
dachshunds t3 or the t4 so you can
unpack the thyroid hormones clintonism
again is caused due to deficiency of
them thyroid hormones so imperialism
there will be retarded mental and
physical growth of children now question
number five match the following so you
have a couple of things in column 1 and
column 2 and you have to match them t44
is a thyroid hormone right so it will
match with thyroid PTH is the pilot
hormone so which is secreted by the
parathyroid so it would match with 4
GnRH that is gonadotropin-releasing
hormone or releasing hormones are
released by the hypothalamus so it will
match with y l h that is luteinizing
hormone which is secreted by the
pituitary so it will match with 3 so
with this we have reached towards the
end of this lesson and I hope that the
this lesson would have helped you and
this way we have also reached towards
the end of the lesson of our class 11 so
see you all in class 12th biology
