Q

Why are we having early puberty’s

A
  • Chemical pesticides
  • environmental stress
  • hormones in food
  • nutrition
21
Q

Primary aging (senescence) is what ?

A

Irreversible changes due to genetic programming

  • gray hair
  • wrinkles
  • weight gain
  • decreased height
22
Q

Secondary aging is what?

A

Changes that are due to illness, health habits, and other individual factors which are not inevitable.

23
Q

Functional age?

A

An individuals physical and psychological well-being

24
Q

Types of old?

A

Young old- healthy and active
Old old- some health problems, and difficulty with daily activities
Oldest old- frail and in need of care

25
Why does brain grow faster than any other part?
- Increased number of interconnections among cells | - Amount of protective myelin increases
26
Rooting reflex?
-Turn head towards things that touch its cheek
27
Moro reflex?
-Activated when support for neck and head is removed. Infant thrusts out arms and try to grasp.
28
Babinski reflex?
Infant fans out toes in response to stroke on the outside of foot
29
Possible indications of neurological problems?
- Abnormal presence of absence of reflex - Unequal bilateral reflex - Persistence of reflex - Emergence of reflex that dropped out
30
Sits w/ slight support (average and range)
``` 1m average (1-5m range) ```
31
Sits alone momentarily (average and range)
6-7m average | 4-8m range
32
Stands alone (ave and range)
10-12m average | 9-14m range
33
Walks alone (ave and range)
``` 12m average (11-15 m range) ```
34
Reaches for object at what month?
5.5m
35
Grasping for object at what month? What types of grasp?
Palmer grasp- birth-5m | Pincer grasp- 7-9m
36
Sensation is what?
-physical stimulation of the sense organs
37
Perception is what?
-mental process of sorting, interpreting, and integrating stimuli from the sense organ/brain
38
Newborns orient to sounds if?
- held properly | - not too brief
39
Newborn distance vision vs 6m infant vision
20/200-20/600 vs 20/20
40
Newborn has 2 kinds of vision limitations
1) getting image | 2) reading image
41
Getting image is what?
-eyes dont always converge on 1 object
42
Reading image is what?
- cones are immature - spaced farther apart - catch 2% of light
43
Preferences that are present from birth? (Infant vision)
- Genetically programed to prefer particular kinds of stimuli - prefer to look at patterned over simpler stimuli
44
When does visual acuity start to decline?
age 40 Declining depth perception and night vision Glaucoma
45
What is Presbyopia?
Loss of near vision
46
What is Glaucoma?
is a disease that damages your eye's optic nerve. It usually happens when fluid builds up in the front part of your eye
47
Describe the vision in late adulthood.
- Lens is less transparent, pupils shrink - Optic nerve less efficient - Cataracts (clouding of the eyes natural lens) - Glaucoma (Damage of eyes optic nerve) - Macular degeneration
48
Macular degeneration?
- Vision loss, center of the field of vision | - Wet: leaky blood vessels grow under retina
