Study Notes

Reaching the Age of Adolescence

  • Adolescence is the period of life where the body undergoes changes leading to reproductive maturity
  • It occurs around the age of 11 and lasts until around 18 or 19
  • Adolescents are also called teenagers
  • Changes vary from person to person

Adolescence and Puberty

  • Puberty is the period of life when the body undergoes changes which mark the ability to reproduce
  • Growth spurt is a noticeable change in height that occurs during puberty
  • The growth spurt begins around ages 10 or 11, and continues until age 18 or 19. Girls generally will start growing at an earlier age.
  • Other changes in body shape occur, including a broader chest in boys (and wider hips in girls), development of hair, and voice changes
  • These changes are controlled by hormones

Changes at Puberty

  • Height increase is prominent during puberty
  • The long bones (legs and arms) lengthen
  • Boys and girls can develop different body shapes; boys usually acquire broader shoulders and wider chests while girls hips will usually widen
  • The rate of growing varies in individuals
  • The rate of growth and height is different for boys and girls and varies from person to person. Height percentage is different in boys and girls by age.

Secondary Sexual Characteristics

  • Secondary sexual characteristics are those traits that develop during puberty, which distinguish males from females and are controlled by sex hormones
  • The development of these characteristics involves changes such as hair growth (facial hair in males and underarm hair and pubic hair for both sexes) and breast development (primarily in females)

Role of Hormones in Reproduction

  • Hormones, chemical substances, regulate changes in the body during puberty and reproduction
  • Hormones are released by endocrine glands into the blood stream to their target site which responds accordingly
  • Testes in males produce testosterone, and ovaries in females produce estrogen, which stimulate secondary sexual traits
  • Pituitary glands control the release of testosterone and estrogen

Reproductive Phase of Life

  • Individuals become capable of reproduction when their ovaries and testes begin producing gametes in puberty.
  • Females reproductive cycle typically lasts from puberty to menopause (around 45 to 50)
  • The menstrual cycle is regulated by hormones and involves the maturation, release, and possible fertilization of an egg.
  • The cycle lasts 28-30 days and involves bleeding (menstruation) unless the egg is fertilized. The cycle can also be irregular initially

Sex Determination

  • Sex of the child is determined by the combination of sex chromosomes in the egg from the mother and sperm from the father.
  • Females have two X chromosomes.
  • Males have one X and one Y chromosome
  • The sex chromosome in the sperm decides the sex of the child. Females will always pass on X

Other Important Changes in Puberty

  • The voice box grows in size, causing boys' voices to deepen
  • Hormonal changes lead to pimples and breakouts on the skin (acne)

Nutritional Needs of Adolescents

  • Adolescents have nutritional needs during rapid growth and development phases
  • A balanced diet is crucial for physical and mental well-being
