Focusing on the prehensile movements of the human hand, Napier(1956) identified two main grip patterns: 

• 1) the power grip, in which the object is held between the surface of the partly flexed fingers and the palm, with the thumb acting as reinforcing agent; and 
• 2) the precision grip, in which the object is pinched between the tips of the fingers and the opposed thumb. 

According to Napier (1956, 1980), anatomical features that facilitate the human ability to

grasp objects precisely and move them with great dexterity include a fully opposable thumb, broad surface of the finger pads, and relatively long thumb with respect to the index finger, which permits full pad-to-pad contact between them. He argued that only humans are capable of applying efficient precision grips to the objects.
