Here's a breakdown:
* Ulnar: Relating to the ulna bone in the forearm, which runs along the pinky finger side of the hand.
* Grasp: A way of holding something with the hand.
Characteristics of an ulnar grasp:
* The object is held between the thumb and the little finger, with the other fingers typically extended or slightly flexed.
* This grasp is often used for small objects like a pen, a button, or a tool.
* It's a precise grip used for tasks requiring dexterity and fine motor control.
Examples of the ulnar grasp in action:
* Writing with a pen
* Picking up a small bead
* Using a screwdriver
In contrast to a palmar grasp:
* Palmar grasp involves holding an object with the whole palm, using all fingers to enclose it. This is typically used for larger objects.
