Last end of spinal cord is called :-

Options

A. Cauda equina
B. Filum terminale
C. Funiculus
D. Conus medullaris

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Spinal Cord**: The spinal cord is a crucial part of the central nervous system that extends from the base of the brain (occipital bone) down to the lumbar region of the vertebral column.

2. **Identifying the Length of the Spinal Cord**: The spinal cord typically extends from the occipital bone to the space between the first and second lumbar vertebrae (L1-L2).

3. **Identifying the Terminal Portion**: The terminal portion of the spinal cord is known as the **Conus Medullaris**. This structure is tapered and located near the lumbar vertebrae.

4. **Evaluating the Options**:
- **Cauda Equina**: This is a bundle of spinal nerves and nerve roots that arise from the lumbar enlargement and conus medullaris. It is not the terminal end of the spinal cord itself.
- **Filum Terminale**: This is a fibrous extension from the conus medullaris that anchors the spinal cord to the coccyx. It is not the last end of the spinal cord.
- **Funiculus**: This refers to a bundle of axons within the spinal cord and is not a terminal structure.
- **Conus Medullaris**: This is the correct answer as it is the tapered end of the spinal cord.

5. **Conclusion**: Based on the evaluation of the options, the last end of the spinal cord is called the **Conus Medullaris**.

**Final Answer**: Conus Medullaris
