Chapter 4: Physical Development in Infancy comprehensive Questions
and Answers with 100% Correct Answers | Latest Version
Are weight gains of infancy are matched by increased length? - (ANSWER)Yes
What does regular height and weight measurements provide.. - (ANSWER)a way to spot problems in
development
What are the four principles of growth? - (ANSWER)Cephalocaudal principle, Proximodistal principle,
Principle of hierarchical integration, Principle of independence of systems
cephalocaudal principle (head to tail) - (ANSWER)the principle that growth follows a pattern that begins
with the head and upper body parts and then proceeds down to the rest of the body
ex. visual abilities develop way before ability to walk
proximodistal principle - (ANSWER)the principle that development proceeds from the center of the body
outward
ex. trunk of the body grows before the extremities of the arms and legs
ex. effective use of the arms precedes the ability to use the hands
Principle of hierarchical integration - (ANSWER)the principle that simple skills typically develop
separately and independently but are later integrated into more complex skills
ex. complex skill of grasping something in the hand cannot be mastered until the developing infant
learns how to control movements of fingers
principle of the independence of systems - (ANSWER)the principle that different body systems grow at
different rates
ex. growth for body size, the nervous system, and sexual maturation are quite different
nervous system - (ANSWER)Composed of the brain, spinal cord, and nerves. Regulates body activities by
sending and receiving messages.
neurons - (ANSWER)a nerve cell; the basic building block of the nervous system

what ability does neurons have? - (ANSWER)communication through dendrites
axon - (ANSWER)the extension of a neuron, ending in branching terminal fibers, through which messages
pass to other neurons or to muscles or glands
How do neurons communicate? - (ANSWER)neurotransmitters (chemical messengers) travel across
synapses (gap between neurons)
What happens to unused neurons? - (ANSWER)The die. (ex: children start recognizing any sound of any
language, but only keep the neurons for the ones they need)
KNOWN AS SYNAPTIC PRUNING
synaptic pruning - (ANSWER)the elimination of neurons as the result of nonuse or lack of stimulation
which allows established neurons to build more networks and become more efficient
do neurons grow in size and reposition their self? - (ANSWER)Yes
myelin - (ANSWER)A layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly
greater transmission speed of neural impulses as the impulse hops from one node to the next.
cerebral cortex - (ANSWER)the upper layer of the brain; responsible for thinking and reasoning
subcortical levels - (ANSWER)below the cerebral cortex
Auditory cortex (temporal lobe) - (ANSWER)conscious processing of sounds
Visual cortex (occipital lobe) - (ANSWER)conscious processing of sights
