Volar and dorsal are anatomical terms used to describe the surfaces of the hand and foot.
- Volar refers to the palm side of the hand or the sole (bottom) of the foot.
- Dorsal refers to the back of the hand or the top of the foot.
Detailed Explanation
To further clarify, consider these points:
-
Volar (Palmar/Plantar): Think of "volar" as relating to the surface you would use to hold something (hand) or stand on (foot). The terms "palmar" and "plantar" are often used interchangeably with volar, specifically referring to the palm and sole, respectively.
-
Dorsal: Imagine a dorsal fin on a dolphin; it's on the back. Similarly, the dorsal surface of the hand or foot is the back surface.
Examples
- A volar splint is applied to the palm side of the forearm, wrist, and hand.
- A dorsal splint is applied to the top side of the forearm, wrist, and hand.
- A dorsal wound on the foot is located on the top of the foot.
- A volar plate injury affects the ligaments on the palm side of the finger.
Summary
In essence, volar refers to the palm/sole side, and dorsal refers to the back/top side of the hand and foot. Understanding these terms is crucial in medical and anatomical contexts for accurate communication and treatment.
