End of spinal cord is

Options

A. Cauda equina
B. Conus terminalis
C. Filum terminalis
D. Funiculus

Answer

### Step-by-Step Solution:

1. **Understanding the Spinal Cord**: The spinal cord is a vital part of the central nervous system. It extends from the base of the brain down to the lower back, specifically starting at the first cervical vertebra (C1).

2. **Identifying the End of the Spinal Cord**: The question specifically asks about the end of the spinal cord. The spinal cord does not extend all the way down to the end of the vertebral column; instead, it terminates at a specific structure.

3. **Recognizing the Structures**: At the end of the spinal cord, there is a structure known as the **conus medullaris** (often referred to as conus terminalis). This structure is cone-shaped and represents the terminal part of the spinal cord.

4. **Understanding Related Structures**: Below the conus medullaris, there are several nerve roots that form a structure known as the **cauda equina**. This term translates to "horse's tail" in Latin, reflecting the appearance of these nerve roots.

5. **Identifying the Final Non-Nervous Structure**: The terminal part of the spinal cord is followed by a non-nervous structure called the **filum terminale**. This structure anchors the spinal cord to the coccyx and is made of connective tissue.

6. **Evaluating the Options**: Given the options:
- 1. Spordiacvena (incorrect)
- 2. Conus terminalis (correct)
- 3. Spinal terminalis (incorrect)
- 4. Spuniculus (incorrect)

The correct answer is **Conus terminalis**.

### Final Answer:
The end of the spinal cord is **Conus terminalis**.
