Question

Quizplus · Accepted Answer

The ulnar grasp is characterized by pressing an object against the palm with the fingers, which is a common developmental stage in infants before they develop the more precise pincer grasp. This type of grasp is named after the ulna, one of the forearm bones involved in this action, reflecting its reliance on the broader movement of the hand rather than the fine motor skills associated with the thumb and forefinger.
