The palmar grasp reflex is an involuntary movement in infants that causes them to grip objects placed in their hands. It is a natural reflex that disappears as the child develops. There are several synonyms for the palmar grasp reflex, including the grasp reflex, hand grasp reflex, and the Palmer reflex. These terms are used interchangeably to describe the same reflex action. The Palmer grasp reflex is also referred to as the prehension reflex, which is a term used to describe the holding and grabbing of objects. Despite the different names used to describe this reflex, it remains a significant developmental stage in infants and a vital indication of their motor function and coordination.
