Somatic nervous system is formed by

Options

A. Ramus dorsalis
B. Ramus communicans
C. Ramus ventrails
D. Both A & C

Answer

To answer the question "Somatic nervous system is formed by," we will analyze the options given and determine which ones are correct.

**Step 1: Understand the components of the Somatic Nervous System (SNS)**
The Somatic Nervous System is part of the peripheral nervous system and is responsible for voluntary control of body movements through skeletal muscles. It consists of sensory (afferent) and motor (efferent) neurons.

**Step 2: Analyze the options provided**
1. **Ramus Dorsalis**: This part carries sensory information from the skin and muscles of the back to the central nervous system. It is indeed part of the somatic nervous system.
2. **Ramus Communicus**: This option is incorrect as Ramus Communicus connects autonomic nerves, not somatic nerves.
3. **Ramus Ventralis**: This part carries motor information to the limbs and trunk. It is also part of the somatic nervous system.
4. **Both A and C**: Since Ramus Dorsalis (A) and Ramus Ventralis (C) are both components of the somatic nervous system, this option is correct.

**Step 3: Conclusion**
Based on the analysis, the Somatic Nervous System is formed by Ramus Dorsalis and Ramus Ventralis. Therefore, the correct answer is option 4: Both A and C.
