  • During infancy (0-2 years), key milestones include rapid growth and the development of motor skills.
  • Arrange the stages of prenatal physical development in chronological order.
    1️⃣ Zygote
    2️⃣ Embryo
    3️⃣ Fetus
  • What is physical development defined as?
    Changes in body structure
  • In the zygote stage of prenatal development, the fertilized egg divides and travels to the uterus.
  • What are the three stages of prenatal physical development?
    Zygote, embryo, fetus
  • During adolescence, boys experience an increase in muscle mass, while girls experience an increase in body fat.

    True
  • Each stage of physical development has unique growth milestones.
    True
  • The development of secondary sexual characteristics signals the maturation of the reproductive system.
    True
  • What is the typical growth pattern for boys during adolescence compared to girls?
    Boys grow faster
  • Stages of prenatal physical development in order
    1️⃣ Zygote (0-2 weeks)
    2️⃣ Embryo (2-8 weeks)
    3️⃣ Fetus (8 weeks-birth)
  • During infancy, infants develop basic motor skills such as rolling over and crawling.
  • When do adults typically reach their peak physical strength and endurance?
    Mid-20s to early 30s
  • What are secondary sexual characteristics developed during puberty driven by?
    Hormonal changes
  • Match the stage of life with its key physical development milestone:
    Infancy ↔️ Crawling
    Childhood ↔️ Improved coordination
    Adolescence ↔️ Puberty
    Adulthood ↔️ Peak physical strength
  • Prenatal physical development occurs during the 9 months of pregnancy.
  • What are two key characteristics of physical development during infancy and toddlerhood?
    Rapid growth, significant milestones
  • Match the physical change with its description during adolescence:
    Height and Weight ↔️ Rapid growth spurt
    Body Composition ↔️ Increase in muscle mass for boys
    Secondary Sexual Characteristics ↔️ Development of breasts in girls
  • Exercise enhances muscle strength and bone density.
    True
  • During childhood, growth plates close and coordination improves.

    True
  • During the embryo stage of prenatal development, organs and body systems begin to form.
  • What are the two main categories of physical changes during toddlerhood (2-3 years)?
    Continued growth, motor refinement
  • What is a key physical change during adolescence for boys in terms of body composition?
    Increase in muscle mass
  • What age range defines adolescence according to this study material?
    12-18 years
  • What happens during the zygote stage of prenatal development?
    Fertilized egg divides
  • What are three key aspects of childhood physical development?
    Growth, motor skills, brain development
  • In late adulthood, there is a gradual physical decline, including decreases in muscle mass and bone density.
  • Puberty during adolescence involves hormonal changes and the development of secondary sexual characteristics.
  • What are two key changes during infancy (0-2 years)?
    Rapid growth, motor skills
  • During childhood, brain myelination enhances cognitive functions.
  • During adolescence, girls typically experience an increase in body fat.
  • What are major stages of physical development across the lifespan?
    Infancy, childhood, adolescence, adulthood
  • The transformation during prenatal development lays the foundation for postnatal physical development.
    True
  • Myelination of neurons in the brain during childhood improves concentration and memory.

    True
  • What are four factors that influence physical development?
    Genetics, nutrition, exercise, environment
