Question 1

primitive reflex is an ____/____ response evoked by a given ____. its purpose is ____ and ____.

Answer 1

Primitive Reflexes : Immediate involuntary response evoked by a given stimulus. Purpose : Movement and Survival

Question 2

Multisensory Reflexes Describe? Integrated? what if retained? Moro

Answer 2

Moro: 0:4 to 0:6 multisensory. when baby’s head is dropped below spine/loud noise arms and fingers extend then flex. baby might cry. if retained likely hypersensitive to sensory stim-profound motor and physiological effects.

Question 3

Position Reflexes Describe? Integrated? what if retained? TLR ATNR STNR

Answer 3

TLR 0:6 months Flexion- prone (fetal position) extension/ supine (birth canal) retained: effects vestibular function and tone ATNR: 0:4-0:6 months turn babies head they put arms in fencing position. helps babies breathe on tummy. retained: issues with rolling, balance, cross midline, visual motor, awkwardness, cog effects. STNR: not present at birth 8:0 to 1:0 reflex of position. head looks up arms raise up lower limbs have gone into flexion. if retained :noticeable with posture will effect tone while moving or sitting.

Question 4

Tactile reflexes of foot/spine Describe? Integrated? what if retained? spinal galant Babinski Plantar

Answer 4

Babinski 0:8-1:0 stroke outer boarder of sole creates foot dorsiflexion and toe extension retained: indicates neurological abnormality, which merits immediate investigation Plantar: 0:9 toes flex when pressure placed on ball of feet. retained: Gravitational insecurity, hypersensitivity, toe-walker.

Question 5

Tactile reflexes of hand/mouth Describe? Integrated? what if retained? Palmar Babkin Rooting

Answer 5

Palmar/ Babkin: 0:4- 0:6 palmar fingers flex around object placed in palm retained Babkin: palmar mandibular response. moves head/mouth opens when palmar initiated. palmar/Babkin retained: manual dexterity lack of separation of hand/mouth movements, Hypersensitivity in the palm of the hand Rooting 0:3 months baby turns towards stimulus to feed. retained: Hypersensitivity, and Poor fine muscle control of the mouth, dribbling.
