What are the two main categories of muscle skills in physical development?

• A. Fine motor skills and gross motor skills
• B. Large muscle skills and small muscle skills
• C. Endurance and flexibility
• D. Balance and coordination

Answer: (B)

The main idea here is the division of muscle skills by the size of the muscle groups involved: gross motor skills use large muscle groups for big, whole-body movements, while fine motor skills use small muscles for precise, delicate tasks. Gross motor skills include actions like walking, running, jumping, and climbing, which coordinate large movements of the arms, legs, and trunk. Fine motor skills involve the hands and fingers (and sometimes the wrists and tonguetips) for tasks like writing, drawing, tying shoes, buttoning, and manipulating small objects. Other options describe fitness attributes or movement qualities rather than the broad category of muscle skills. Endurance and flexibility are about physical fitness components, and balance or coordination are particular movement abilities that can be part of either gross or fine motor skills but don’t define the two main categories.
