Ever wonder why your baby flings his arms out sideways when startled? This reaction - called the Moro reflex - is one of many natural reflexes your newborn should exhibit. Read on to learn about common newborn reflexes and what they mean.

The righting reflex, also known as the labyrinthine righting reflex, or the Cervico-collic reflex; is a reflex that corrects the orientation of the body when it is taken out of its normal upright position.

The first of the righting reflexes to appear is the neck righting reflex. It is present at birth in a normal full term baby and strongest at about three months of age. It is triggered by stretching of the neck muscles when there is rotation of the head or movement of the cervical/neck spine.

2022年12月30日 · Postural reflexes are complex motor responses that provide automatic control of posture, balance, and coordination. They are characterized by a certain stereotyped posture of the trunk, head, and extremities when the examiner attempts …

2020年3月15日 · The Righting reflex is one of the first reflexes to appear post-birth, emerging between 0-2 months of age. The majority of the other primitive reflexes don’t emerge until later in our development, usually between 3 to 6 months of age.

2023年5月1日 · This reflex is essential for postural tone and stability, gross and fine movements, eye tracking, and midline crossing crucial for reading, telling the time, left-right discrimination, etc. On the other hand, symmetrical tonic neck reflex (STNR) appears 6 to 9 months after birth until 9 to 11 months of age.

2024年12月29日 · Postural reflexes depend on a complex network of sensory feedback systems that constantly monitor the body’s position and surroundings. One such reflex is the neck righting reflex, a primary reflex present at birth that is most significant around three months of age.

We attempt to identify the important role the nervous system plays in maintaining reflex control of the spine and posture. We also review, illustrate, and discuss how the human vertebral column develops, functions, and adapts to Earth's gravity in an upright position.
