Physical Self Flashcards
Refer to the body both physical extremities and internal organs work together to perform many of its functions.
Physical Self
This stage is characterized by rapid physical changes that include the maturation of the reproductive system
Puberty
Refers to the development from conception to death
Life Span
Two factors affecting physical growth & development?
- Heredity
2. Environment
The biological process of the inheritance of traits from parents to offspring.
Heredity
Refers to the factors an individual is exposed to throughout life which includes learning and experiences.
Environment
[T or F} Particularly, the physical changes that occur at the start of adolescence result largely from the secretion of various hormones which virtually affects every aspect of an adolescent’s life, particularly the way they view themselves.
True
[T or F] Generally, boys are more dissatisfied than girls with their physical appearance and their overall body image.
False
[T or F] In general, the body performs least during infancy but generally peaks in early adulthood between the ages of twenty and thirty and then slowly declines into the middle age.
True
Threadlike tissues that carries the genes, and are usually found in pairs.
Chromosomes
[T or F] Sex and other physical traits are determined by the combination of chromosomes and genes during fertilization
True
How many pairs of chromosomes there are?
23 pairs
Trait chromosomes
Autosomes (22 pairs)
Sex chromosomes
Gonosomes
[T or F] The sex of the offspring depends on the pairing of the sex chromosomes (23rd) from the father and mother.
True
The basis carrier of the hereditary traits
Genes
Classification of Genes
Dominant: strong genes
Recessive: weak genes
[T or F] Physical efficiency generally peaks in early adulthood between the ages of twenty and thirty, then slowly declines into the middle age.
True
[T or F] Physical development and growth during childhood continue at a slower rate compared to the rapid rate of growth in babyhood.
True
Fertilization to birth
Prenatal
Birth to 2 weeks
Infancy
2 weeks to 2 years
Babyhood
2-6 years old
Early childhood
6-10 or 12 years old
Late Childhood
10-12 or 14 years old
Puberty
14-18 years old
Adolescence
18-40 years old
Early Adulthood
40-60 years old
Middle Adulthood
60 to death
Late Adulthood or Senescence
Refers to the fertilized ovum or single-celled organism that represents the start of human life.
Zygote
2nd week to the 2nd month; life support systems like the heart, nervous system, stomach, esophagus, and gonads are developed.
Embryo
Starts 2 months after conception and lasts for 7 months.
Fetus
Where do fetus gets nourishment?
Placenta
How many blood vessels of umbilical cord connect the placenta and the fetus.
Three
Purpose of the three blood vessels.
One is to send nutrients while the remaining two is to filter out wastes.
Fetus is immersed in a fluid-filled [blank] that cushions it against sudden movements or physical blows to the mother.
Amniotic sac
[T or F] A newborn’s eyesight is estimated to be 20/300, but by 6 to 12 months, visual acuity improves to about 20/20
True
[T or F] Newborns can hear soft voices and turn their heads towards sounds at the age of 2 or 3 years old.
True
[T or F] Infant prefer looking at human faces and patterned materials. They also prefer the smells of flowers and taste of sweet drinks.
True
[Infant Reflexes] The infant opens his or her mouth for feeding
Rooting
[Infant Reflexes] The infant grasps the item and can hold on very well.
Gripping
[Infant Reflexes] The inner sole is stroked, the inner curls his or her toes.
Toe Curling
[Infant Reflexes] The infant throws his or her head back and arms and legs out then cries.
Moro or startle
[Infant Reflexes] The infant curves toward the side that was stroked and looks like a fencer when doing so.
Galant
Preschool years
Engagement in physical activities
Early Childhood
No single growth phase similar to all
Signs of puberty appears
Late Childhood
Growth and body changes
Middle and Late Childhood
Made up of clear sequence
Period of biological maturation
Increase in height of 2 inches and 6.5 pounds gain a year.
Puberty
[T or F] Girls begin their growth spurt by the age of 10 1/2 and are taller than their male peers by the age of 12 while boys begin their growth spurt by the age of 12 1/2 but usually grow faster and for a longer period of time than girls.
True
Three substages of adulthood
Early (20-40), Middle (40-65), and Late (65 onwards)
Physical growth continues
Early adulthood
Loss of sensory acuity, risk of certain diseases increases and fertility declines, menopause in women.
Middle adulthood
Men shrink about an inch and women about 2 inches. Body systems gradually slow down and become less efficient. Brain shrinks and the blood flow to the brain slows down.
Late Adulthood
