The functional relationship between the autonomic nervous system and skeletal muscle can be best described as:

A. Excitatory via sympathetic neurons
B. Inhibitory via parasympathetic neurons
C. Modulatory, determining the speed of contraction
D. Non-existent, as skeletal muscle is under somatic control
✓

📝 Explanation

Skeletal muscle is exclusively innervated and controlled by the somatic nervous system (voluntary control). The autonomic nervous system (sympathetic and parasympathetic) controls cardiac muscle, smooth muscle, and glands.

📖 Additional Information

  • Excitatory via sympathetic neurons
  • Inhibitory via parasympathetic neurons
  • Modulatory, determining the speed of contraction
  • Non-existent, as skeletal muscle is under somatic control
