Chapter 4.1 physical growth and development in infancy Flashcards
cephalocaudal pattern
Developmental sequence in which the earliest growth always occurs at the top—the head—with physical growth in size, weight, and feature differentiation gradually working from top to bottom.
proximodistal pattern
Developmental sequence in which growth starts at the center of the body and moves toward the extremities.
lateralization
Specialization of function in one hemisphere of the cerebral cortex or the other.
neuroconstructivist view
A belief that biological processes and environmental conditions influence the brain’s development; the brain has plasticity and is context dependent; and development of the brain and cognitive development are closely linked.
sudden infant death syndrome (SIDS)
A condition that occurs when an infant stops breathing, usually during the night, and suddenly dies without an apparent cause.
How much does a newborn gain in the first month?
Around 5 to 6 ounces a week
Around which month did they doubled there birthwight?
Around 4 months
How many neurons do they have?
Approximately 100 bilion nerve cells
What is shaken baby syndrome?
Injury to head/brain which includes brain swelling and hemorrhaging
Frontal lobes are involved in:
- Voluntary movement
- thinking
- personality
- intentionality or purpose
Occipital lobes function:
- vision
Temporal lobes function:
- hearing
- language processing
- memory
Parietal lobes function?
- registering spatial location
- attention
- motor control
Why do we sleep?
- Evolutionary perspective; All animals sleep so it is necessary for survival.
- Sleep replenishes and rebuilds the brain and body.
Sleep is essential to clearing out waste in neural tissues - Critical for brain plasticity
How much does the typical newborn sleeps approximately?
Around 18 hours a day. But can be 10 hours to 21 hours
