Fine motor skills involve which muscle groups?

Fine motor skills involve which muscle groups?

• A. Large Muscle Groups
• B. Small Muscle Groups
• C. No Muscle Involvement
• D. Mixed Muscle Groups

Answer: (B)

Fine motor skills rely on the small muscles of the hands, fingers, and wrists to perform precise, controlled movements. These tiny muscles allow fine, accurate actions such as writing, buttoning a shirt, or threading a needle. In contrast, large muscle groups handle gross motor skills—big movements like running, jumping, or throwing that involve bigger, stronger muscles but less precise control. While some tasks may use coordination from larger muscles too, the defining feature of fine motor skills is the involvement and control of small muscle groups. So the small muscle groups are what underpin fine motor skills.
