The term "manual" is a reference to which area of the body?

The term "manual" is derived from the Latin word "manus," which translates to "hand." In anatomical terminology, "manual" specifically refers to anything pertaining to the hands, such as movement or dexterity. This connection to the hands is important in fields like medicine and therapy, where manual skills are emphasized for diagnosis, treatment, and care. The other options refer to broader or different areas of the upper extremities, but the term "manual" specifically hones in on the functionality and characteristics associated with the hands.
