autonomic movements that control the equilibrium we require once upright and moving
maintain posture
balance fluidity of movement

Question 9

Vestibular (Tonic Labyrinith) reflex= High tone of extensor muscles in all 4 limbs
like babies! when limbs extend, head extands too

Neck reflexes-

baby is lying on the back, head is towards right side. also right arm will be extand, and the left arm will flex
