Final answer:
A Power grip is a grasp that uses the opposition of the thumb towards the fingers to hold and manipulate objects, usually for heavy or large items.
Step-by-step explanation:
A Power grip is a type of grasp used by the hand to hold, carry, and manipulate objects, leveraging the opposition movement of the thumb toward the fingers of the same hand. This grip is characterized by the simultaneous application of force by all the fingers and the thumb, which enables a firm hold on an object, making it especially useful for handling heavy or large items that require a secure grasp. The power grip contrasts with precision grips, which involve more delicate and accurate manipulations often with the thumb and one or more fingers, geared towards tasks requiring fine motor skills.
