PUBERTY
UNIT-I
The main headings are given in the BLUE colour
Main Subheadings are given in the YELLOW colour
Subheadings are given in the Green colour
CHARACTERISTICS OF PUBERTY
It is a unique and distinctive period which never happens again
1) Puberty is an overlapping period
Closing of childhood and beginning of adolescence, until people are sexually mature,
they are ‘Pubercent’
2) Puberty is a short period
2 or fewer years are rapidly mature
3 to 4 years are slow to mature
3) Puberty stages
Prepubescent- Secondary sexual character begins, developing reproductive organs, but
not fully developed
Pubescent- Cells are produced in the sex organ, nocturnal emission
Postpubercent- Begin to function in a mature manner
4) Puberty is a time of rapid growth
It is called a Puberty growth spurt. These changes lead to confusion, feeling of
inadequacy, and unfavourable behaviour.
5) Puberty is a Negative phase
Anti-attitude towards life, losing some good qualities
6) Puberty occurs at variable age
For different people, different period
CRITERIA OF PUBERTY
Urine, X-ray of bone development, nocturnal emission, menarche
CAUSES OF PUBERTY
, In past, it was a mystery. The hypothalamus send a signal to the pituitary gland through the
gonadotropin-releasing hormone
Luteinizing hormone
Follicle-stimulating hormone
AGE
12.5-14.5 girls, average-13
14-16.5 Boys. average- 14
GROWTH SPURT
Sudden growth
Increase in height, weight, strength
● Based on hereditary factors
● Endocrine gland influence
● Environmental factors
● Nutrition
● Emotional disturbance- causing overproduction of adrenal steroids which harm growth
hormone
Illness, poor nutrition, and tension cause a delay
BODY CHANGES
Change in size
Change in height and weight
Boys have longer growth periods- so boys achieve great height
Weight- fat, muscle, bone
Changes in Body Proportion
From too small to too bid
- Apparent in the nose, feet and hands
- Most changes take place before puberty is over
- The trunk lengthens, the waistline drops
- The broadness of hips and shoulders is influenced by the age of maturing
- Who mature, late puberty slight growth
- Everything starts to get mature except the leg, nose and hands
- Trunk and legs determine the body proportions
- Legs and arms will be long for late mature
