infant BIOLOGICAL DEV. Flashcards
the perception of depth produced by the reception in the brain of visual stimuli from both eyes in combination; binocular vision
STEREOPSOSIS - begins to develop by age 7-9 months
when does STEREOPSOS begin to develop
7-9 months
this is immature at birth; human milk compensates for the 1st several months
digestive process
how does an infant compensate for an immature digestive process?
by human milk
until what age an infant receives maternal protection / immunologic system
until about 3 months of age
rate that begins to slow in infants ; is a relatively stable
respiratory rate
kind of HR that increases with inspiration, decreases with expiration
SINUS ARRYTHMIA
Fixation of 2 ocular images into 1 cerebral image
fusion
at what age does binocularity begin to develop
by 6 weeks
at what age does binocularity should be well established
by 4 months
duration of the presence of fetal hemoglobin (hemapoietic changes)
first 5 months
for infants, looking at the human face
visual preferences
this is caused by high levels of fetal hemoglobin, which is thought to depress the production of erythropoietin
physiological anemia
what caused physiological anemia
high levels of fetal hemoglobin
during infancy, this rate slows down, with sinus arrhythmia commonly seen
heart rate
rate increases during infancy, is relatively stable
resp rate
term often used to denote breast-feeding
sucklin
propelling forward on hands, and knees with belly off floor
creeping
when does creeping usually occur
at around 9 months
enzyme needed to achieve adult levels of fat absorption
lipase
in infants, this enzyme sufficiently secreted to catabolize protein
trypsin
this appears in utero as early as 15-18 wks of gestation with maturation, synchronized with swallowing and breathin patterns by 36-38 wks
sucking
when does sucking appear?
in utero, 15-18 wks of gestation
complete maturation of sucking, swallowing, & breathing patterns are usually synchronized by
36-38 wks
