A reflex is an involuntary muscle reaction to a certain type of stimulation. Certain sensations or movements are known to produce specific muscular responses.
Primitive reflexes; Reflexes in infants; Tonic neck reflex; Galant reflex; Truncal incurvation; Rooting reflex; Parachute reflex; Grasp reflex
The presence and strength of a reflex is an important sign of neurological development and function.
Many infant reflexes disappear as the child grows older, although some remain throughout adulthood. The presence of an infant reflex after the age at which the reflex normally disappears can be a sign of brain damage or damage to the nervous system.
Infant reflexes are reflexes that are normal in infants, but abnormal in other age groups. Such reflexes include:
- Sucking reflex (sucks when area around mouth stimulated)
- Startle reflex (pulling arms and legs inward after loud noise)
- Step reflex (stepping motions when sole of foot touches hard surface)
