Infancy Flashcards
(164 cards)
growth starts from the top part of the body (i.e., brain to foot)
o Cephalocaudal Principle
growth proceed from the center of the body outward (e.g., Palm (grasping) to fingers)
o Proximodistal Principle
o Children grow faster during
first 3 years
o Teething usually begins
around 3-4 months
o Growth slows in
second year of life
o Growth isn’t often smooth and continuous but rather ?
episodic, occurring in spurts
o– brain’s growth occurs in fits and starts
Brain Growth Spurts
(maintains balance and motor coordination) grows the fastest during the first year of life
Cerebellum
specialization of the hemispheres
o Lateralization
concerned with language and logical thinking
o Left Hemisphere
concerned with visual and spatial functions
o Right Hemisphere
– tough band of tissue that joins the two hemisphere which allows them to share info and coordinate commands
o Corpus Callosum
smallest; concerned with visual processing
o Occipital
involved with integrating sensory info from the body; movement and manipulation of objects
o Parietal
interpret smells and sounds and involved in memory
o Temporal
involved in high-order processes such as reasoning and problem solving
o Frontal Lobe
– outer surface of the cerebrum; grows rapidly in the first few months and are mature by age 6 months
o Cerebral Cortex
o Brain Growth Spurt begins at
about the third trimester of gestation and continues until at least the 4th year of life
send and receive info in the brain
o Neurons
nourish and protect the neurons
o Glia or Glial Cells
– sends signals to other neurons
o Axon
receive incoming messages
o Dendrites
tiny gaps which are bridged with the help of chemicals
o Synapses
neurons that control various groups of muscle coordinate their activities
