The pincer grasp is the ability to use the thumb and index finger opposably, allowing for the grasping and manipulation of small objects. The grasp reflex is an automatic reflex that occurs in newborns but does not involve intentional manipulation of objects. The ulnar grasp involves using the fingers to grip objects and is a precursor to the pincer grasp. Prereaching is an early reaching movement seen in infants, but it does not involve the use of the thumb and index finger in grasping objects.
