sõrmehaaramisega

Sõrmehaaramisega refers to a reflex observed in human infants known as the grasp reflex. This involuntary motor response causes a baby's fingers to close around an object placed in their palm. The reflex is typically present from birth and can be quite strong, allowing some newborns to briefly support their own weight when their hands are grasped.

The grasp reflex is considered a primitive reflex, meaning it is present in early infancy and usually disappears as the central nervous system matures. It is thought to be a remnant of our evolutionary past, possibly serving a protective function or aiding in clinging to a caregiver. While the exact neurological pathways are complex, the reflex involves sensory receptors in the palm that trigger motor neurons to contract the finger muscles.

The presence and strength of the grasp reflex are often assessed by healthcare professionals during infant examinations to gauge neurological development. A weak or absent grasp reflex, or one that persists beyond the typical age of disappearance (usually around 3-4 months), may indicate underlying neurological issues and warrant further investigation. The reflex generally fades as voluntary control of the hands develops and more complex motor skills emerge.
