Puberty Upper body of a teenage boy. The structure has changed to resemble an adult form. Puberty is a period of several years in which rapid physical growth and psychological changes occur, culminating in sexual maturity. The average age of onset of puberty is at 11 for girls and 12 for boys.
Hormones play an organizational role, priming the body to behave in a certain way once puberty begins,  and an active role, referring to changes in hormones during adolescence that trigger behavioral and physical changes.
It is the stage of life characterized by the appearance and development of secondary sex characteristics for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls and a strong shift in hormonal balance towards an adult state.
This is triggered by the pituitary glandwhich secretes a surge of hormonal agents into the blood stream, initiating a chain reaction to occur. The male and female gonads are subsequently activated, which puts them into a state of rapid growth and development; the triggered gonads now commence the mass production of the necessary chemicals.
The testes primarily release testosteroneand the ovaries predominantly dispense estrogen. The production of these hormones increases gradually until sexual maturation is met.
Some boys may develop gynecomastia due to an imbalance of sex hormonestissue responsiveness or obesity.
The first facial hair to appear tends to grow at the corners of the upper lip, typically between 14 and 17 years of age. This is followed by the appearance of hair on the upper part of the cheeks, and the area under the lower lip.
Facial hair is often present in late adolescence, around ages 17 and 18, but may not appear until significantly later. Early maturing boys are usually taller and stronger than their friends.
Pubescent boys often tend to have a good body image, are more confident, secure, and more independent. However, early puberty is not always positive for boys; early sexual maturation in boys can be accompanied by increased aggressiveness due to the surge of hormones that affect them.
Nearly half of all American high school girls' diets are to lose weight. Girls attain reproductive maturity about four years after the first physical changes of puberty appear.
Adolescence is marked in red at top right. Growth spurt The adolescent growth spurt is a rapid increase in the individual's height and weight during puberty resulting from the simultaneous release of growth hormones, thyroid hormonesand androgens.
The weight gained during adolescence constitutes nearly half of one's adult body weight.
The first places to grow are the extremities—the head, hands and feet—followed by the arms and legs, then the torso and shoulders. During puberty, bones become harder and more brittle.Acculturation is the process of social, psychological, and cultural change that stems from blending between cultures.
The effects of acculturation can be seen at multiple levels in both the original (native) and newly adopted (host) cultures.
Historically speaking, acculturation is a direct change of one's culture through dominance over another's culture through either military or political. Teaching word meanings should be a way for students to define their world, to move from light to dark, to a more fine-grained description of the colors that surround us.
What time should the school day begin? School start times vary considerably, both across the nation and within individual communities, with some schools beginning earlier than a.m. and others after a.m. Districts often stagger the start times of different schools in order to reduce transportation costs by using fewer buses.
