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
