Question 3

Adult Neuro: primitive reflexes and associated reaction

It is also known as the “fencing reflex,” when the face is turned to one side, the arm and leg on the side to which the face is turned extend and the arm and leg on the opposite side flex.

Answer 3

asymmetrical tonic neck reflex

Question 4

Adult Neuro: primitive reflexes and associated reaction

Flexion of the neck results in flexion of the arms and extension of the legs; extension of the neck results in extension of the arms and flexion of the legs.

Answer 4

symmetric tonic neck reflex

(a tonic reflex)

Question 5

Adult Neuro: primitive reflexes and associated reaction

Prone lying position facilitates flexion; the supine position facilitates extension. The reflex can also be thought of as inhibition of extensor tone in the prone position.

Answer 5

symmetrical tonic labyrinthine reflex

Question 6

name of reflex

This is initiated by a change in the position of the upper trunk with respect to the pelvis. Rotation of the trunk to the right results in flexion of the right upper extremity and extension of the right lower extremity; rotation of the trunk to the left results in extension of the right upper extremity and flexion of the right lower extremity.

Answer 6

tonic lumbar reflex

Question 7

Adult Neuro: primitive reflexes and associated reaction

Resistance applied to abduction or adduction of the nonaffected lower extremity evokes a similar reaction in the affected limb.

Answer 7

Raimiste’s Phenomenon

Question 8

Adult Neuro: primitive reflexes and associated reaction

Flexion in the UE causes flexion of the ipsilateral LE

Answer 8

Homolateral Limb Synkineses
