Options

A. Sympathetic
B. Parasympathetic
C. Both of these
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the term "craniosacral outflow" and which part of the autonomic nervous system it refers to.

2. **Identifying the Autonomic Nervous System**: The autonomic nervous system is divided into two main parts: the sympathetic nervous system and the parasympathetic nervous system.

3. **Defining Craniosacral Outflow**: The term "craniosacral outflow" specifically refers to the parasympathetic nervous system. This is because it originates from the cranial nerves and the sacral region of the spinal cord.

4. **Contrasting with Sympathetic Outflow**: In contrast, the sympathetic nervous system is associated with "thoracolumbar outflow," which originates from the thoracic and lumbar regions of the spinal cord.

5. **Conclusion**: Since craniosacral outflow is linked to the parasympathetic nervous system, the correct answer to the question is "parasympathetic."

**Final Answer**: Craniosacral outflow refers to the **parasympathetic** nervous system.
