Autonomic nervous system controls :

Options

A. Conditioned reflexes
B. Functioning of spinal cord
C. Functioning of visceral organs
D. Reflex actions

Answer

To solve the question "Autonomic Nervous System controls:", we will analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding the Autonomic Nervous System (ANS)**:
- The ANS is a part of the peripheral nervous system that controls involuntary bodily functions. It regulates the functions of internal organs and glands without conscious control.

2. **Analyzing Option 1: Conditioned Reflexes**:
- Conditioned reflexes are learned responses to stimuli. They involve higher brain functions and are not controlled by the autonomic nervous system. Instead, they are associated with areas of the brain like the hippocampus and basal ganglia.
- **Conclusion**: This option is incorrect.

3. **Analyzing Option 2: Functioning of Spinal Cord**:
- The spinal cord is primarily part of the central nervous system (CNS) and is responsible for reflex actions and transmitting signals between the brain and the rest of the body. It does not fall under the control of the autonomic nervous system.
- **Conclusion**: This option is also incorrect.

4. **Analyzing Option 3: Functioning of the Visceral Organs**:
- The ANS directly controls the functioning of visceral organs such as the heart, lungs, and digestive organs. It is divided into the sympathetic and parasympathetic systems, which manage bodily responses to stress and relaxation, respectively.
- **Conclusion**: This option is correct.

5. **Analyzing Option 4: Reflex Actions**:
- Reflex actions are quick responses to stimuli that are primarily mediated by the spinal cord and do not involve the autonomic nervous system. They are more related to the somatic nervous system.
- **Conclusion**: This option is incorrect.

### Final Answer:
The Autonomic Nervous System controls the functioning of the visceral organs (Option 3).
