Verified step by step guidance

Step 1: Begin by understanding the term 'visceral reflexes.' Visceral reflexes are involuntary responses that regulate the function of internal organs, such as the heart, lungs, and digestive system. These reflexes are part of the autonomic nervous system.

Step 2: Analyze the options provided in the question. The first option, 'sensory perception of external stimuli,' refers to the somatic sensory system, which is responsible for detecting external stimuli like touch, temperature, and pain. This is not related to visceral reflexes.

Step 3: Evaluate the second option, 'voluntary movement of limbs.' Voluntary movements are controlled by the somatic motor system, which involves conscious control of skeletal muscles. Visceral reflexes are involuntary and do not involve voluntary limb movement.

Step 4: Consider the third option, 'conscious control of skeletal muscles.' Skeletal muscle control is part of the somatic nervous system and requires conscious effort, whereas visceral reflexes operate automatically without conscious control.

Step 5: Focus on the correct answer, 'automatic regulation of internal organ function.' Visceral reflexes are specifically designed to regulate internal organ functions automatically, such as adjusting heart rate, blood pressure, and digestion, ensuring homeostasis within the body.
