The term "pulgar" refers to the thumb in Spanish. It is the short, thick digit located on the side of the hand, opposite the fingers. The thumb plays a crucial role in grasping and manipulating objects, making it essential for various tasks, from writing to using tools. In anatomy, the thumb is unique because it has a greater range of motion compared to the other fingers. This flexibility allows for a strong grip and precise movements. The thumb's opposability, which means it can touch the tips of the other fingers, is a key feature that distinguishes humans from many other animals, enhancing our ability to perform complex tasks.
