OTH 506: midterm exam || with 100% Errorless Answers.
when does the infant totally concur gravity? correct answers middle infancy
when does the infant achieve symmetrical postures in midline? correct answers middle infancy
is the infant able to participate in complicated patterns by middle infancy? correct answers - no,
tends to participate more in total patterns of limbs
what time frame is middle infancy? correct answers 4-6 months
when is the infant able to participate in prone on elbows? correct answers middle infancy
what are the 2 purposes of righting reactions? correct answers - to orient body parts with respect
to gravity and the environment
- allows rotation around the axis of the body parts to support change (make it right when you feel
wrong)
what is the neck righting (de-rotative) reaction? onset? integration? significance? correct answers
- onset: 4 months
- integration: persists throughout life; dominant in first 5 years
- flex and rotate the Childs head and the body will respond by de-rotating into alignment with the
head
- significance: forms a basis for nearly all transitions, such as rolling over and sitting up
what is the body on body righting reaction? Onset? integration? correct answers - onset: 4-6
months
- integration: persists throughout life; dominates in the first 5 years
- child in supine with head in the midline, lift and rotate leg across body and the body will de-
rotate- child will rotate body parts into alignment thereby rolling over
What is the body-on-head righting reaction? onset? integration? significance? correct answers -
onset: birth - 2 months
- integration: persists throughout life
- body on firm surface, head rotates into alignment with body or surface on which it lies
- significance: complements neck righting
what is the optical righting reaction? onset? integration? significance? correct answers - onset:
birth - 2 months
- integration: persists throughout life
- tilt head to one side or forward/back, head orients to matin vertical contact with the visual
(similar to labyrinthine but can only tell a difference when blind folded)
- significance: complements labyrinthine righting
is rolling segmental or rotary? what reflexes are required? correct answers - rotary (infant doesn't
roll like a pancake or a log)
, - requires tonic labyrinthine and labyrinthine righting
What is the landau reaction? onset? integration? significance? correct answers - onset: 4-6
months
- integration: one year
- prone suspension; full extension of body against gravity
- significance: is a critical milestone in the mastery of anti-gravity control (is an indication that
all righting reactions are present)
when is the baby able to hold their head up against gravity? correct answers about 5 months
mid infancy
what is a neonate? correct answers the term used to describe an infant from birth to one month
what does prone mean? normal motor behaviors of a newborn within the first month in this
position? correct answers - lying face down
- head bobs reflexively but is usually turned to one side, whole body conforms to gravity
what does supine mean? normal motor behaviors of a newborn within the 1st month in this
position? correct answers - face up
- flexion and lateral rotation, head to one side, hands fisted
what is the tonic labyrinthine reflex? onset? integration? correct answers - onset: prenatal
- integration: 6 months
- prone: flexor tones dominant; child will not lift head
supine: extensor tine dominates
what is the labyrinthine righting reaction? onset? integration? significance? correct answers -
onset: birth to 2 months
- integration: persists throughout life
- Head orients to vertical position and is steady, maintained in proper orientation to environment
when tilting the body in all directions
- significance: will prohibit anti-gravity behaviors
what is the asymmetric tonic neck reflex? onset? integration? correct answers - onset: birth to 2
months
- integration: 4-6 months
- Extension of the arm and leg to which the face is turned; flexion of the opposite limbs
explain "sits forward propped". when is it present? correct answers - emerges about 6 months
(middle infancy)
- baby sits in a position where they are sitting on there butt, but have to be leaning forward
because they feel displaced and due to downward protective extension, arms extend when the
body mass is displaced and you're likely to fall
- due to symmetrical tonic neck reflex
