Reaching the age of adolescence - Lecture 1 Video Lecture - Class 8

fellow children to deviant will do study
something about another sense the naming
would have permitted there and CBS
is reaching the age of adolescence know
what is adolescence actually the growth
begins from the day one is born but upon
crossing the age of ten or eleven there
is a sudden spurt in growth which
becomes noticeable growth is a natural
process the period of life leading to
reproductive maturity is called s
adolescence period of life leading to
reproductive maturity
in adolescence it begins around the age
of eleven and lasts up to 18 for 19
years now
there is one more term that is called as
puberty it is a period of sexual
maturity when reproductive organs become
functional
when reproductive organs
because functional
a human females age of puberty ends 10
to 14 years and in males the puberty
period is 13 to 16 years it is a
transition stage in adolescence now let
us discuss something about the changes
activity what are the changes brought
about at puberty period the first
important change that is brought about
is increase in honey there is a sudden
increase in height the height increases
due to the elongation of bones in the
body arms and legs get longer
along with internal body organs height
of a person mainly depends on the genes
that they inherit from their parents but
nutritional factors are also important
in growth initially girls grow faster
than the boys but by about 18 years and
will both reach their maximum height at
18 years maximum height is reached the
second important change that is brought
about at liberty is change in the body
shape body shape changes third important
changes the voice box or lavenders
begins to grow fourth important changes
there is an increased activity of
increased activity of sweat and
sebaceous glands
next is development of sex organs and at
puberty this is also called as the stage
of reaching mental intellectual
and emotional maturity
now there are some secondary sexual
characteristics and boilers these
secondary sexual characteristics
especially in case of girls development
of breast
drawing
vending machine
and beginning of the menstrual cycle
the secondary sexual characteristics of
boys are as follows
development of bill and stats
voice becomes deeper
development of pubic hair
now let us discuss something about the
role of hormones in adolescence
during the period of Liberty children
the sexo rules bring about changes of
the body these are called a secondary
sexual characteristics which are which
we have already developed which we have
already discussed I'm sorry
so there are many hormones which are
responsible for development of these
characters in our body that we are going
to discuss later on
now let us the main hormones which are
responsible for development of these
characters they are thought they are
released from the pituitary they are
mainly follicle stimulating hormone and
luteinizing hormone which are
responsible for release of female and
male hormones in their body we are going
to discuss these hormonal part in detail
later on
let us discuss something about the
reproductive health
now any human population different
individuals are at different stages of
the government of life such as infants
children juveniles adolescent and ageing
reproductive health of society depends
upon certain factors depends on some
factors which are as follows first
important factor is education of the
young people
health of the young people
nutritional needs of adolescents
early marriage and child rearing is also
a very important factor
now if I talk about the education of
young people there is correlation
between the state of education and birth
weight it named states with low literacy
rate have high population growth by it
states with high literacy rate have low
population growth rate now if I talk
about the health of you will then the
women tend to have fewer and he has
their children young people have the
highest infection of sexually
transmitted diseases third point states
that adolescence is a state of rapid
growth of development it is important to
eat balanced food and maintain personal
hygiene during adolescence early manages
increased death rate of infants and
ladies also women between 15 to 19 years
faced more complications of pregnancy
childbirth and unsafe abortion generally
lead to their death
let us talk something about the very
important idea which is quadrants
menstrual cycle which occurs in female
and it is a mark of adolescent a stage
now what is menstrual cycle it is a
cycle which involves the series of cycle
changes in the ovaries of humans it is a
series of cyclic changes in the ovaries
of females
during the reproductive period during
the reproductive period
the reproductive period of human
exchange of ability and it it is termed
as menarche
and Menaka starts from 10 to 14 years of
age to menopause which is around 45 to
55 years of age during this period
children every month our menstrual cycle
occurs whose peculiar feature is period
the vagina and bleeding that lasts for
four days so period is actually what it
is the vagina bleeding which lasts for
four days primary movement recycles to
prepare the female for fertilization and
pregnancy during the menstrual cycle
there are a few phases the wall of the
uterus passes through the several phases
which are controlled by two hormones
this cycle is controlled by two hormones
which I called as a surgeon and
progesterone
the first phase of münster cycle usually
lasts for four to six days during this
period the lining of the uterus has shed
accompanied by a loss of length this
duration of first phase is called as
rodents period this phase is called as
minstrel phase or registration menstrual
phase or it can also be called as
menstruation
now let us discuss something about the
methods to control overpopulation
there are few methods which which are
really helpful in controlling
overpopulation the first one of them is
education young people should be
educated that will really lead to
control the overpopulation age of
Madam's next factor is age of marriage
it should be 18 years for females and 21
years for males 18 years for females and
21 years for males the third important
factor which can control over population
is family planning methods
chemical and mechanical method like
contraceptives our UCD birth control
pill should be made available to every
level mainly an awareness awareness
about these methods should be spread
forth is literacy rate should be
increased literacy rate should be
increased so that people will be more
and more educated and they will be aware
of the severe effects of overpopulation
social organization should also be
involved in this field job facilities
should be provided to the many
your facilities should be provided to
women community health program should be
implemented we should implement
Community Health Program
now children let us these were all the
methods to control the overpopulation
let us discuss something about the
determination of sex
actually to determine the sex there are
chromosomes responsible and these
chromosomes are of two types they can be
partisans or they can be
hello souls hello Soames can also record
as heteros ohms or they can be called as
sex chromosomes
on the other hand what assumes can be
called as a somatic chromosomes
the autosomes of the somatic chromosomes
they regulate the regulate the somatic
characters of an organism on the other
hand Allison's are the chromosomes which
are associated with sex determination
sex chromosomes were discovered by
McClung McClung was the person who was
first discovered these other souls in a
grasshopper X chromosome especially was
discovered by hanging and called as X
body by him now
XS we made an ex white male this is the
condition of human beings xx female and
XY is me we are discussing the condition
which is present in case of human beings
okay
now children in case of female there are
46 chromosomes total out of that 44
chromosomes are somatic Romo zooms and
one pair of chromosome is a sex
chromosome in female which is xx and
making a female in case of male 44 are
the somatic chromosomes and one pair
that is XY chromosome is a sex
chromosome final now this will form two
gametes 22 plus X 22 plus X on the other
hand in case of males 22 plus X + 22 + y
these are the getting's found now if I
cross this game is if this she being a
man gets uses with this one it will form
44 plus xx
if this one chooses with this milk a
meal then this will form 44 plus ex-wife
same is the kids here with this if this
see William it combines with this
William it it will form 44 plus xx and
if this is combining with this mayhem it
it will fall 44 plus XY out of these
since we know that female consists of
homeotic chromosomes so this will be an
email this will be a male this is again
female and this is again a male
so this is how sex is determined and
ultimately we can say that father is
only responsible for the sex of a child
now there are some sexually transmitted
diseases also let us discuss them the
main important sexually transmitted
disease
if
this is a very important belief are the
whales the full form of AIDS is acquired
if you know deficiency syndrome
the causative organism for this is HIV
that is human immuno deficiency virus
the symptoms of these disease include
weakness loss of appetite loss of weight
there are many symptoms first is
weakness loss of weight loss of appetite
fever swelling in the lymph nodes
now how it can be transmitted @j we can
pass on to another person from an
infected person by sharing the syringes
for injecting drugs it can also be
infected it can also be transmitted from
infected mother through her milk to the
baby
the virus can also be transmitted
through sexual contact with a person
infected with HIV so this was all about
the eh Thank You June
