Which part of the upper limb is referred to as "manual"?

The term "manual" is derived from the Latin word "manus," meaning hand. In anatomical terminology, it specifically refers to the hand as the part of the upper limb that is involved in highly intricate movements, manipulative tasks, and fine motor skills. The hand consists of numerous bones, muscles, tendons, and ligaments that facilitate a wide range of functions, such as grasping, holding, and precision movements. This anatomical region plays a crucial role in daily activities and interactions with the environment, which is why it is commonly referred to in contexts related to manual dexterity, manual labor, and other hand-related functions.
