Neural canal is located in

Options

A. cranium
B. Skull
C. vertebra
D. spinal cord

Answer

To solve the question "Neural canal is located in," we will analyze the options provided and understand the concept of the neural canal.

### Step-by-Step Solution:

1. **Understanding Neural Canal**:
- The neural canal refers to a system of cavities that are found in the vertebrae of an embryo. These cavities eventually develop into the ventricles of the brain and the central canal of the spinal cord.

2. **Analyzing the Options**:
- **Option 1: Cranium**:
- The cranium is part of the skull that encloses the brain. It does not contain the neural canal itself. Therefore, this option is incorrect.

- **Option 2: Skull**:
- The skull consists of the cranium and the mandible. Similar to the cranium, it does not contain the neural canal. Thus, this option is also incorrect.

- **Option 3: Vertebra**:
- The neural canal is located within the vertebrae. This is where the system of cavities is found, making this option correct.

- **Option 4: Spinal Cord**:
- The spinal cord is a structure that runs within the vertebral column, but it is not where the neural canal is located. The neural canal is a precursor to the spinal cord's central canal. Hence, this option is incorrect.

3. **Conclusion**:
- After analyzing all the options, the correct answer is **Option 3: Vertebra**.
