An athlete performs a complex gymnastics routine. How do the skeletal, muscular and nervous systems interact to maintain balance?

  1. Nerves receive sensory input, muscles respond, and skeleton provides stability
  2. Muscles contract randomly while nerves send signals to bones
  3. Skeletal system provides leverage while muscles and nerves are inactive
  4. Bones move independently of muscular and nervous input

\(A\)

Show Worked Solution
  • A is correct: The three systems work together with nerves detecting position, muscles making adjustments, and bones providing structural support.

Other Options:

  • B is incorrect: Muscle contractions are coordinated, not random
  • C is incorrect: Muscles and nerves are actively working, not inactive
  • D is incorrect: Bones cannot move without muscle and nerve involvement
