Verified step by step guidance
1
Understand the role of the autonomic nervous system (ANS): The ANS is responsible for involuntary control of body functions, such as heart rate, digestion, and glandular activity. It innervates structures like smooth muscle, cardiac muscle, and glands.
Review the types of muscles in the body: Skeletal muscle is under voluntary control and is innervated by the somatic nervous system, not the autonomic nervous system. In contrast, cardiac muscle and smooth muscle are involuntary and controlled by the ANS.
Examine the salivary glands: Salivary glands are innervated by the autonomic nervous system to regulate saliva production, which is an involuntary process.
Analyze the smooth muscle of the intestines: Smooth muscle in the intestines is controlled by the autonomic nervous system to regulate peristalsis and other digestive movements.
Conclude that skeletal muscle does NOT receive innervation from the autonomic nervous system, as it is under voluntary control and innervated by the somatic nervous system.
