Which of the nervous system transmit impulse from CNS to involuntary organs & smooth muscle?

Options

A. Sympathetic nervous system
B. Parasympathetic nervous system
C. Autonomic nervous system
D. Somatic nervous system

Answer

To solve the question, "Which of the nervous systems transmits impulses from the CNS to involuntary organs and smooth muscle?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific part of the nervous system that transmits impulses from the Central Nervous System (CNS) to involuntary organs and smooth muscles.

2. **Identify the Nervous System Components**:
- **Sympathetic Nervous System**: This part of the autonomic nervous system prepares the body for 'fight or flight' responses. It is involved in involuntary responses but is not the only system responsible for transmitting impulses to involuntary organs.
- **Parasympathetic Nervous System**: This system helps to calm the body down after the 'fight or flight' response. It also deals with involuntary functions but is not the main system that transmits impulses to involuntary organs.
- **Autonomic Nervous System**: This is the key component that regulates involuntary bodily functions, including the transmission of impulses to involuntary organs and smooth muscles.
- **Somatic Nervous System**: This system controls voluntary movements and is responsible for sending signals to skeletal muscles, not involuntary organs.

3. **Analyze the Options**:
- The **Sympathetic** and **Parasympathetic Nervous Systems** are parts of the **Autonomic Nervous System**, but they do not solely represent the entire system responsible for involuntary functions.
- The **Autonomic Nervous System** is the correct answer as it encompasses both the sympathetic and parasympathetic systems and is responsible for involuntary actions.
- The **Somatic Nervous System** is not involved in involuntary control.

4. **Conclusion**: Based on the analysis, the correct answer is the **Autonomic Nervous System** as it transmits impulses from the CNS to involuntary organs and smooth muscles.

### Final Answer:
The nervous system that transmits impulses from the CNS to involuntary organs and smooth muscle is the **Autonomic Nervous System**.
