Final answer:
Innervation of skeletal muscle is not a function of the autonomic nervous system.
Step-by-step explanation:
Autonomic Nervous System Functions
Innervation of cardiac muscle, innervation of smooth muscle of the digestive tract, and innervation of glands are all functions of the autonomic nervous system.
In contrast, innervation of skeletal muscle is not a function of the autonomic nervous system. The somatic nervous system is responsible for innervating skeletal muscles, which are considered voluntary muscles.
