Neural canal contains

Options

A. Ear ossicles
B. Internal ears
C. Spinal cord
D. Brain.

Answer

**Step-by-Step Solution:**

1. **Understanding the Neural Canal**: The neural canal is a cavity or system of cavities located within the vertebral column. It is formed during the development of the vertebrae in embryos.

2. **Function of the Neural Canal**: The primary function of the neural canal is to house and protect the spinal cord. It also plays a role in forming the ventricles of the brain.

3. **Identifying the Contents of the Neural Canal**: The neural canal specifically contains the spinal cord. This is the main structure that runs through the canal.

4. **Excluding Other Options**: The other options provided (ear ossicles, internal ears, and brain) do not belong to the contents of the neural canal.
- Ear ossicles are small bones in the middle ear.
- The internal ear is involved in hearing and balance, but it is not located within the neural canal.
- The brain, while it is connected to the spinal cord, is housed in the cranial cavity, not the neural canal.

5. **Conclusion**: Based on the definition and function of the neural canal, it is clear that the correct answer is that the neural canal contains the spinal cord.

**Final Answer**: The neural canal contains the spinal cord.
