A task requiring precise finger movements would be categorized as which level of muscular involvement?

• A. Gross
• B. Fine
• C. Start and Finish
• D. No Obvious Start or Finish

Answer: (B)

Precise finger movements rely on fine motor control, which uses small muscle groups in the hands and fingers to perform accurate, delicate actions. Tasks like threading a needle or playing a piano require this high level of control, so they’re categorized as fine motor involvement. Gross motor control, by contrast, uses larger muscle groups for bigger, less precise actions like running or jumping. The other terms describe how a task progresses in time rather than which muscles are used; they don’t indicate the level of muscle involvement.
