Question 9

Rooting

Answer 9

perioral stroke results in head turning to side with mouth open.0-3 months

Question 10

Sucking

Answer 10

touch to lips tongue and palate results in autonomic sucking. 0-6 months

Question 11

Tonic Labyrinthine reflex

Answer 11

pron position results in max flexor tone and supine reults in max extension tone. If reflex persist may inhibit infants ability to roll due to increased tone 0-6 months

Question 12

Asymmetric Tonic Neck Reflex

Answer 12

rotation of head results in extension of UE and LE on face side and flexion of UE and LE on skull side. If reflex persist may result in scoliosis, hip dislocation, and interfere with grasping. 0-5 months

Answer 17

head orients itself to a vertical position when the body is tilted. TEST with the eyes blind folded. 1 month throughout life.

Question 18

Protective extension

Answer 18

trunk goes into downward direction…. to catch weightDownward- 4 months, Sideward sit- 6months, Forward sit 7 months, Backward sit 9 moths These reaction persist throughout life

Question 19

Body righting reacion (BOH)

Answer 19

contact of body with solid surface causes head righting. interacts with labyrinthine reaction. used to maintain orientation of head in space 4-6 months.

Question 20

Body righting reaction acting on the body

Answer 20

rotation of head or thrax causes rolling over with rotation between the trunk and pelvis begins 6-8 months

Question 21

Symmetric tonic neck reflex

Answer 21

extension of cervical joints causes extenson of upper extremities and flexion of lower extremities. Flexion of the cervical joints causes flexion of the upper extremities and extension of the lower extremities. (6-8 months)

Landau reaction

Answer 22

if infant is held in ventral suspension extension of the neck, trunk and hips. 4-8 months

Question 23

Tilting reaction

Answer 23

shifting of BOS or displacement of body in space results in lateral flexion of spine toward elevated side of support, Abd of extremities on elevated side, and sometimes trunk rotation toward elevated side. Prone 5mth, Supine 7mth, sit 8mths, quadped 12mth
