Intro Flashcards
gestational age
37-42 weeks is considered full term
Germination period
Embryonic period
Fetal period: 8 weeks to term “fetus”
neonate/newborn=
first couple weeks
infant =
to 12 months
APGAR score
10 point scale
Given at 1 and 5 minutes after birth
Most babies don’t have a 10 right away, anything >7 is good
Heart Rate:
0= absent
1= < 100
2= > 100
Resp Rate:
0= absent
1= slow & irregular
2= good, crying
Muscle Tone:
0= limp
1= some flexion & ext
2= active movement
Reflex Irritability:
0= no response
1= grimace
2= cough or sneeze
Color:
0= blue
1= pink, blue extremities
2= pink
Reflexes are ____ at birth
present at birth and are integrated
develop to assist the child
primitive reflexes at birth, over time become integrated (increased myelination, increased strength and weight, exposure to different positions and increased stimulation)
protective response reflex later develop as infant grows
what are 2 feeding reflexes?
1- rooting reflex
2- sucking reflex
what is the rooting reflex?
touch to cheek results in turning head to same side with mouth open
disappears usually by 3 months
interferes with oral motor development, development of midline control of head, optical righting, visual tracking and social interaction
what is the sucking reflex?
touch to lips, tongue, palate results in automatic sucking
follows the rooting and allows the infant to take in food
disappears by 6 months
interferes with progression of oral motor foods and solid intake
what is the moro reflex?
head drop into/ suddenly results in arm abduction then adduction
disappears by 5 months
interferes with balance reactions and protective responses in sitting, eye-hand coordination, visual tracking
what is the startle reflex?
loud, sudden noise results in Moro response with elbows flexed and hands closed
disappears by 5 months
interferes as Moro and also social interaction and attention
what are 2 grasping reflexes?
1- palmar grasp
2- plantar grasp
what is the palmer grasp reflex?
pressure in infant’s palm results in strong fist and grip then a slow release
disappears by 4 months
interferes with ability to grasp and release objects voluntarily, weight bear on open hand
what is the plantar grasp reflex?
pressure to base of toes results in toe flexion
disappears by 9 months
interferes with ability to stand with flat feet, balance reactions and weight shifting in standing
what are 3 attitudinal reflexes?
1- Asymmetrical tonic neck reflex (ATNR)
2- Symmetrical tonic neck reflex (STNR)
3- Tonic labyinthine reflex
what is ATNR?
Asymmetrical tonic neck reflex
head turned to 1 side results in arm & leg extension on face side and flexion on scalp side
disappears by 6 months
interferes with feeding, tracking, midline use of hands, B hand use, rolling, crawling, and can lead to skeletal deformities
what is STNR?
Symmetrical tonic neck reflex
neck flexion produces UE flexion and LE extension
neck extension produces UE / and LE flexion
normal age from 6-8 months
interferes with POE (prone on elbows), quad, crawling, sitting balance looking and use of hands in this position
what is TLR?
tonic labyrinthine reflex
in supine, body and extremities are in extension and in prone they are in flexion
disappears by 6 months
interferes with ability to initiate rolling, POE, supine to sit, balance in sitting or standing
what are 4 protective extension reflexes?
1- parachute response
2- forward sitting
3- sideways sitting
4- backwards sitting
what is the parachute response?
quick displacement of trunk downward with child suspended in prone at 45 degrees results in arm extension
present at 4 months
what is protective extension in forward sitting?
push child forward in siting and arms should extend to catch weight
present in 6-7 months
