The somatic neural system and relays impulses

Options

A. From CNS to involuntary organs
B. From CNS to involuntry muscles
C. From PNS to smooth muscles
D. From PNS to voluntary organs

Answer

**Step-by-Step Solution:**

1. **Understand the Neural System**: The somatic neural system is often referred to as the voluntary nervous system. It primarily controls voluntary movements by relaying impulses from the Central Nervous System (CNS) to skeletal muscles.

2. **Identify the Components**: The nervous system is divided into two main parts: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The PNS is further divided into the somatic (voluntary) and autonomic (involuntary) nervous systems.

3. **Differentiate Between Somatic and Autonomic Systems**:
- The somatic nervous system controls voluntary actions, such as moving your arms or legs.
- The autonomic nervous system controls involuntary actions, such as heart rate and digestion.

4. **Analyze the Options**:
- Option 1: From CNS to involuntary organs - This relates to the autonomic nervous system, not somatic.
- Option 2: From CNS to involuntary muscles - This also pertains to the autonomic system.
- Option 3: From PNS to smooth muscle - This is incorrect as smooth muscle is controlled by the autonomic system.
- Option 4: From PNS to involuntary organs - Again, this relates to the autonomic system.

5. **Select the Correct Answer**: The correct interpretation is that the somatic nervous system relays impulses from the CNS to voluntary muscles, which means the correct answer is that the somatic neural system relays impulses from the CNS to voluntary muscles.

**Final Answer**: The somatic neural system relays impulses from the CNS to voluntary muscles.
