A tennis player executes a powerful serve. Which statement best describes the nervous system's role?

  1. Only processes visual information from the ball toss
  2. Coordinates sensory input, muscle activation and balance
  3. Only controls muscle contraction timing
  4. Only maintains postural stability during the movement
Show Answers Only

\(B\)

Show Worked Solution

Consider Option B: Coordinates sensory input, muscle activation and balance

The nervous system

  • integrates visual information from the ball toss
  • coordinates the timing of multiple muscle contractions throughout the kinetic chain
  • maintains balance through sensory feedback throughout the service motion

Other Options:

  • A is incorrect: Omits muscle control aspects
  • C is incorrect: Ignores sensory processing required
  • D is incorrect: Misses coordination requirements

\(\Rightarrow B\)
