Basic reflexes of newborns:unconditioned and conditioned reflexes

Twenty-eight days – exactly the period lasts
newborn during which the child’s body experiences
adaptation to completely new conditions for him now
extrauterine life, so the reflexes of a newborn baby are played
here is the main role.

devoid of many useful skills – nature takes care of him.

Basic reflexes

В этом периоде у малыша развиты только безусловные
– то есть, те, которые заложены как бы по умолчанию.
Gradually, some of them disappear, giving way to conditional.

Условные рефлексы еще можно назвать «личным опытом»
child as they are acquired in the process of further
development and maturation of the brain.

What are unconditional (innate) reflexes for?

Clinically significant unconditioned reflexes in the baby as much
Fifteen – and their “fate” is very different: some are needed only
in order to survive the difficult process of birth (so they
disappear quickly after birth), others – to give
impetus to the development of new, and still others remain for life.

Pediatric neonatologists divide inborn reflexes
newborns into several groups:

  1. Providing the general normal activity (respiratory,
    sucking, swallowing, and spinal reflexes)
  2. Aimed at protecting the child’s body from external
    effects of bright light, cold, heat and other irritants
  3. �”Temporary” reflexes – for example, a breath hold reflex,
    necessary to advance through the birth canal of the mother.

Оральные рефлексы

The ability to suck the maternal breast or the nipple on the bottle with
искусственным питанием называется сосательным рефлексом, а
способность проглотить съеденную пищу – глотательным.

Сосательный рефлекс возникает в первые часы жизни и

Глотательный рефлекс остается на всю жизнь.

Хоботковый рефлекс – еще одна разновидность оральных
reflexes. If it is easy to touch the lips of the baby, they are ridiculously bulging
into a tubule – just like a baby elephant’s trunk, because at this moment

Рефлекс Бабкина (ладонно-ротовой) – смешанная
a kind of reaction of the child, in which he opens his mouth,
if you gently press with your thumbs at the same time on both palms.
Best expressed in the first two months of life, the third begins

Рефлекс Куссмауля (поисковый) – попытка найти еду: если
touch the corner of the child’s mouth, he turns his head to an irritant.
Disappears quickly enough – three to four months after
of birth. In the future, the search for food occurs visually – the baby sees
breast or bottle.

Spinal reflexes. Looking around baby
immediately after birth and during the entire neonatal period,
pediatrician pays attention to spinal reflexes – set
reactions responsible for the state of the muscular system.

Upper protective reflex. One of the most
important unconditioned reflexes starting in the first hours
life, – the upper protective reflex. It manifests itself if
put a newborn baby on the belly: immediately to the side
the head turns, and the baby tries to lift it. It –

Grasp reflexes

Рефлексы Янишевского и Робинсона у
newborn baby show up when it clutches tight
with both hands on the fingers of the mother (the doctor) and is able to hold them
so strong that it can even be lifted in this way.
They are expressed up to three to four months, then weaken.
Preserving these reflexes at a later age is evidence
existing neurological problems.

Рефлекс Бабинского – его еще называют подошвенным
reflex: lightly stroking the edges of the soles outside causes
opening of the fingers in the form of a fan, while the legs are bent from the back
parties. Evaluation criteria are energy and especially –
symmetry of movements. One of the most долгоживущих врожденных рефлексов
– it is celebrated up to two years.

Other motor reflexes

Рефлекс Моро – двухфазная реакция, при которой ребенок
responds to a rather loud knock on the changing table or any
another harsh sound.

  • The first phase – the baby spreads his arms to the side and unclenches
    fingers, straightening with the legs.
  • The second phase is the return to the previous position. Sometimes a child with
    this may even be like a hug – so the Moro reflex still has
    one name is “hug reflex”.

Pronounced before the age of five months baby.

Рефлекс «автоматической» походки, являющий собой весьма

Рефлекс опоры – попытка малыша встать на стопы, когда
he, carefully holding, put on a flat surface (on the table,
eg). It – двухфазный рефлекс: сначала малыш, почувствовав
a touch of support, sharply bends the legs at the knees, and then –
It becomes both feet and firmly presses the soles to the table.
Well pronounced reflexes of support and “automatic” gait
persist for one and a half months.

Рефлекс Бауэра (спонтанное ползание) можно наблюдать,
putting the baby on his stomach and putting his palms to his soles: he
begins to crawl, starting from the created support and helping
yourself hands. Appearing for 3-4 days, this reflex disappears later
3-4 months.

Weak reflexes or when you need to sound the alarm

It so happens that some of the baby’s reflexes are included with
late or do not appear very clearly. It may be
due to trauma from childbirth, illness, and
prove to be an individual response to certain medications.

Also, the weakness of oral and spinal reactions is usually noted in
premature babies and those born with mild asphyxia.

Interestingly, weak reflexes in a newborn baby,
associated with the search for food and its absorption (sucking and swallowing),
can be explained only by the fact that the baby is simply not hungry.
Most clearly they appear before feeding.

Most frightening is the situation when there are no reflexes.
Complete lack of reflexes in the newborn
child – a reason for immediate resuscitation, which should
carry out only specialists.

The reasons for this are different – intrauterine malformations, severe generic
injuries, deep asphyxia (asphyxiation of the umbilical cord).

However, it should be remembered: the reserves of the children’s body are enormous,
therefore, in many cases, it is quite successfully restored, and
baby grows up healthy.
