reflex is a muscle reaction that occurs automatically in response to a certain type of stimulation.Some feelings or human movement produce concrete answers muscles.The availability and strength of a reflex is an important sign of the development and function of the nervous system.
Many children's reflexes disappear as the child grows older, although some of them remain throughout his adult life.The presence of children at the age of reflex, in which children's reflex usually disappears can be a sign of brain damage or damage to the human nervous system.
Infant reflexes that are normal in infants, but abnormal in other age groups include:
- Moro reflex;
- suckling (sucking, there is no need, for any touch);
- startle reflex (sip hands and feet after hearing a loud noise);
- stepping reflex (stepping movements as soon as the soles of the feet to a solid surface).
There are other children's reflexes.
- The tonic neck reflex - occurs when you move in the direction of the baby's head, which lay quietly on his back.The position of the neck is often described as the position of a fencer, because it looks like a fencer's pose.
-Tulovischnoy bending or Galant reflex - occurs when a stroke along the spine while the baby is lying on his stomach.The baby will pull his hips, making movements like dance.
-Hvatatelny reflex - occurs when an adult puts finger on open palm baby.Baby's hand closed around an adult finger.Attempting to remove the finger causes the clutch or tightening.Newborns have a strong grip and can almost overpower the adult, if both hands grab his finger.
- rooting reflex - occurs when an adult touches the child's cheek.The baby turns its face to the side, with which it stroked and begin to make sucking movements mouth.
- Reflex parachute - occurs in children more older, an adult holding a baby in an upright position, and then quickly turns his body facing forward (as if it drops - so some parents play with a child).The child will stretch his hands forward as if preventing the fall, though this reflex appears long before the child learns to walk.
Examples of reflexes that persist into adulthood:
- blinking reflex - blinking of the eyes, when they were touched, or when there is suddenly a bright light;
- cough reflex - cough occurs whenever the organism there is a need to stimulate the respiratory tract;
- gag reflex - when stimulated by the throat or back of the mouth;
- ptarmic reflex - sneezing occurs when the nasal passages are irritated;
- zevatelny reflex - yawning occurs when the body needs more oxygen.
Infant reflexes can occur in adults who have:
- brain damage;
- nervous system disorders.
doctor usually discovers abnormal reflexes children during the body examination for any other reason.Reflexes, which lasts after they are supposed to go through, may be a sign of a child's nervous system problems.
Parents who are concerned about the development of your child, or who have noticed that the children's reflexes continue their child after they had already stopped, should tell your doctor.
doctor would perform a diagnostic examination of the child and parents to ask questions about the history of the child's illness.
Questions may be, for example, are:
- some reflections have a child;
- at what age the child some reflexes had disappeared;
- which also have more symptoms of a place (for example, decreased alertness or seizures).
