Verified step by step guidance

Understand the role of the autonomic nervous system (ANS): The ANS is responsible for involuntary control of visceral functions, such as regulating heart rate, glandular secretion, and smooth muscle activity. It does not control voluntary movements or skeletal muscle contraction, which are managed by the somatic nervous system.

Identify the key components of autonomic reflexes: Autonomic reflexes involve sensory input from visceral organs, integration in the central nervous system (CNS), and motor output to effectors such as glands, smooth muscle, or the heart.

Analyze the options provided: Glandular secretion and heart rate are both visceral functions controlled by the ANS. Skeletal muscle contraction and voluntary movement are not controlled by the ANS but by the somatic nervous system.

Relate glandular secretion to the ANS: The ANS regulates glandular secretion through parasympathetic and sympathetic pathways. For example, the parasympathetic system stimulates salivary gland secretion, while the sympathetic system can inhibit it.

Relate heart rate to the ANS: The ANS controls heart rate through the sympathetic and parasympathetic divisions. The sympathetic division increases heart rate during stress, while the parasympathetic division decreases heart rate during rest.
