Lecture 1 Part 2 Flashcards
An embryo becomes a fetus at ___________
8 weeks
First trimester is how many weeks?
What happens?
1-12 weeks
All major body systems are established
Second trimester includes what weeks?
What happens?
13-26 weeks
Body proportions grow to newborn proportions
Third trimester includes what weeks?
What happens?
27-40 (note: so you’re technically pregnant for 10 months)
Body weight triples and body length doubles
Bodyfat accumulates to aid temperature regulation
When are the lungs developed
36 weeks
What is included in the STORCH acronym?
Syphilis
Toxoplasmosis
Other infections (HIV, Coxsackievirus, Varicella-Zoster)
Rubella
CMV
Herpes
Directionally: Typical development goes from ____________ to __________
Cephalic to caudal
Proximal to distal
gross motor to fine motor
What test is used by the delivering medical team to assess the infant
Apgar score
Total score 1-10
Higher the score = better the baby is doing
What is considered premature birth?
What is considered extreme premature?
Past what week will they induce a delivery?
Under 38
Under 28
Over 42
Between what weeks is it normal to give birth
38-42
Describe a newborn posture
UE:
LE:
Head:
UE: Flexion and hands fisted
LE: Flexed w/ highly positioned pelvis
Head: turned to one side
When a newborn is in supine, what posture should you expect
UE:
LE:
Head
UE flexion
LE flexion, abduction, ER
Head turned to one side
If you pull a newborn to a seated position what should you expect to see at their head?
Head lag
When a newborn is seated what kind of posture do they have?
What happens to their head?
Posture - C curve throughout with no anti-gravity extension
Head forward w/ no control and head bobbing
Newborns prefer what kind of color scheme?
At what distance is their vision best?
Strong contrasting colors
Best 8-9 inches away
What happens if a child does not display the normal primitive reflexes
“Involuntary movements eventually become voluntary movements” - meaning that they need reflexes to develop skilled voluntary movement
They will struggle with motor and cognitive skills
If a child retains their primitive reflexes for too long, what can this mean
developmental delays
What activates the flexor withdrawal reflex?
What is the reflex consist of?
A noxious stimulus to the sole of the foot
flexion withdrawal of the leg
When does the flexion withdrawal reflex appear
When does it integrate
At approximately 28 weeks of gestation
integrates at 1-2 months of age
What is the crossed extension reflex?
What triggers it?
Caused by noxious stimuli to the sole of the opposite foot
While one foot withdrawals, the other has extension and adduction
When does the crossed extension reflex first appear
when does it integrate?
28 weeks of gestation
integrates between 1-2 months of age
(same as the flexor withdrawal reflex)
What is the positive support/primary standing reflex?
If you hold a baby up and touch their feet to flat surface, they will extend their legs against the ground for 20-30 seconds
When does the positive support/primary standing reflex first appear
when does it integrate?
appears at 35 weeks gestation
integrates after 1-2 months
