These skills are called unconditioned reflexes - the simplest automatic actions controlled by the primitive centers of the brain and spinal cord. Some reflexes appear together with the crumbs, that is, from birth, and some - a little later.

All newborn reflexes have pronouncedprotective function. The main tasks that they carry: the protection of vital organs and help in adapting to life in the environment, in fact, ensuring the survival of man in various stages of maturation.

With about four months of age is the ability to fade, and replace it comes already conscious gripping objects of interest of the child.
  5. Reflex Galant. If you retreat to 1.5 cm from the long axis of the spine and soft touch in this area, the baby immediately vygnet arc back toward the stimulus.

These reflexes are controlled by the medulla oblongataand the center of the midbrain. In the future, these reflexes (after timely extinction) will help the newborn to learn motor skills such as standing, crawling, and then sitting and walking.

  1. Symmetrical and asymmetrical tonic neckreflexes. The first is that if you tilt the baby's head to his chest, then he starts to bend and straighten arms and legs. And if the child lying on the back to turn the head so that it will be on his shoulder, he immediately razognet arms and legs, which bend and facing the opposite - it will be asymmetrical reflex.
  2. The labyrinth tonic reflex. When the child is lying on his back, this reflex is actively coached extensor muscles, and when the stomach - flexor muscles.
  3. Neck rectifying reaction. This reflex is controlled by the brain has an average center and looks just like a coup from the back to the belly that so pleases the parents.

  5. Protective reaction arms. Also controlled by the average center of the brain and is manifested in a rather conscious change in the position of pens in accordance with the change in his body position in space.
  6. Landau reflex. If you raise the baby in the air in the form of a swimmer, the person looked down, he immediately raises his head and razognet torso, arms and legs.

Nature is very well taken care of and thought outeach step of growing a little man, and language functioning unconditioned reflex acts can tell a lot.
