Chapter 7 - The Human lifespan Flashcards
What are the Areas of human development?
Physical
Intellectual
Emotional
Social (Jobs)
Physical development definition
Refers to the changes that occur to the body and its systems
Physical development definition
Refers to the changes that occur to the body and its systems
What are the Aspects of Physical Development?
Growth- eg. people get bigger until the end of puberty
Changes to body systems- egg. increase of complexity of the brain, changes to sex organ function during puberty, and decline of body systems
Motor Skill Development-
Fine motor skills: eg. writing, cutting with scissors, tying shoelaces
Gross motor skills: eg. running, throwing a ball, riding a bike
What are the 3 periods of rapid growth during the human lifespan?
- Puberty
- Prenatal
- Infancy
What are the changes to body systems?
Tissue and body systems also change in structure and function
eg:
-replacement of baby teeth with permanent teeth
-hardening of bones until early adulthood
-change in the way sex organs functions during youth
-development of the immune system
When is the usual physical peak?
Early 20s-30s
What are examples of physical decline?
-Decrease in muscular strength
-Gradual loss of bone density
Decrease in elasticity of skin
-Decline in sensory organs (eyes, ears, nose, tongue and skin)
-Thickening walls of the arteries
what are motor skills?
refers to the control of the muscles in the body
what are gross motor skills?
movements that involve large muscle groups
eg- walking, throwing, skipping and kicking
what are fine motor skills?
control over the smaller muscle groups
eg- writing, tying shoelaces, cutting with scissors, manipulating the mouth to speak.
physical transitions from youth to adulthood
growth;
-girls grow 16cm (10-13) and 16kg in weight. boys grow 20cm (12-15) and 20kg in weight
-end of youth the epiphyseal plates in long bone fuses and no more growth is possible.
changes to body systems;
-changes of the reproductive systems including sex organs and the way they function
primary sex characteristics;
-the body that is directly involved in reproduction
secondary sex characteristics;
-changes that occur to both males and females but are not present at both and not directly related to reproduction
what are the female sex characteristics?
primary:
-first ovulation
-first menstruation
-the ovaries, uterus, vagina, labia and clitoris enlarge
secondary:
-skin becomes oily
-body hair develops including underarm and pubic hair
-increased fat to muscle ratio
-breasts develop
-hips widen
what are the male sex characteristics?
primary:
-penis enlarges
-first ejaculation
-testes grow and start producing sperm
secondary:
-skin appears oily
-facial hair appears
-voice lowers
-shoulders broaden
-increased stature
-increased muscle mass
-body hair develops including pubic, underarm, chest and arm hair
what is motor skills development?
-by the end puberty, the arms and legs are proportionate to the rest of the body and coordination improves. as the body matures during the youth, the individual will gain more control over it.
