Question

which is not an effector innervated by the autonomic nervous system? multiple choice cardiac muscle smooth muscle glands skeletal muscle

Explanation:

The autonomic nervous system (ANS) innervates effectors that function involuntarily. Cardiac muscle (involuntary, regulated by ANS), smooth muscle (involuntary, e.g., in organs/blood vessels, innervated by ANS), and glands (e.g., sweat, endocrine glands, controlled by ANS) are innervated by the ANS. Skeletal muscle is innervated by the somatic nervous system, which controls voluntary movements, so it is not innervated by the autonomic nervous system.

Answer:

D. Skeletal muscle
