puberty

Examples of puberty in the following topics:

• Puberty

  • Puberty is the process through which a child matures and becomes capable of sexual reproduction.
  • Puberty that starts earlier than usual is known as precocious puberty.
  • Puberty that starts later than usual is known as delayed puberty.
  • Girls usually complete puberty by ages 15–17, while boys usually complete puberty by ages 16–18.
  • Normal puberty is initiated in the hypothalamus.

• Physical Development in Adolescence

  • During puberty, an adolescent experiences a period of rapid physical growth that culminates in sexual maturity.
  • The onset of puberty typically occurs at age 10 or 11 for females and at age 11 or 12 for males; females usually complete puberty by ages 15 to 17, while males usually finish around ages 16 to 17.
  • Females tend to attain reproductive maturity about four years after the first physical changes of puberty appear.
  • While the sequence of physical changes in puberty is predictable, the onset and pace of puberty vary widely.
  • During puberty, bones become harder and more brittle.

• Male Hormones

  • The onset of puberty is controlled by two major hormones: FSH initiates spermatogenesis and LH signals the release of testosterone.
  • Puberty is a period of several years in which rapid physical growth and psychological changes occur, culminating in sexual maturity.
  • The average onset of puberty is age 11 or 12 for boys.
  • Hormones play an organizational role, priming the body to behave in a certain way once puberty begins, and an activational role, referring to changes in hormones during adolescence that trigger behavioral and physical changes.
  • At the onset of puberty, the hypothalamus begins secreting high pulses of GnRH, or gonadotropin-releasing hormone.

• Childhood

  • In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty).
  • Developmentally and biologically, it refers to the period between infancy and puberty.
  • In most western societies, middle childhood begins at around age seven or eight, approximating primary school age and ends around puberty, which typically marks the beginning of adolescence.
  • Adolescence is usually determined by the onset of puberty.
  • However, puberty may also begin in preadolescents.

• Acne

  • Enlargement of sebaceous glands and an increase in sebum production occur with increased androgen production during puberty and directly before menstruation.

• The Rite of Passage

  • The rite of passage is typically a ceremonial event in which a person enters into a new phase of life, such as puberty or marriage.
  • Scarification has been widely used by many West African tribes to mark milestone stages in both men and women's lives, such as puberty and marriage.
  • Often referred to as female genital mutilation (FGM), it can be carried out on girls from a few days after birth to puberty.
  • Many cultures used scarification to mark a rite of passage such as puberty.

• Testes

  • The tubules are lined with a layer of cells (germ cells) that develop into sperm cells (also known as spermatozoa or male gametes) from puberty into old age.
  • Leydig cells, localized between seminiferous tubules, produce and secrete testosterone and other androgens important for sexual development and puberty including secondary sexual characteristics like facial hair, sexual behavior.

• Transitional Adulthood

  • In Islam, children are not required to perform any obligatory acts of Islamic teachings prior to reaching the age of puberty, although they should be encouraged to begin praying at the age of seven.
  • Before reaching puberty it is recommended to pray in obeisance to Allah and to exemplify Islamic customs, but as soon as one exhibits any characteristic of puberty, that person is required to perform the prayers and other obligations of Islam.

• Biological Differences

  • However, males enter puberty on average two years later than females (it is important to note, however, that females have a clear sign (e.g., menarche) of puberty onset whereas males (and their parents) are generally uncertain of the exact onset of puberty, which could skew these interpretations).

• Ovaries

  • Estrogen is responsible for the appearance of secondary sex characteristics of females at puberty and for the maturation and maintenance of the reproductive organs in their mature functional state.
