Step 1: Break Down the Problem

To answer the question, we need to identify the anatomical position where the spinal cord terminates in the human body.

Step 2: Relevant Concepts

The spinal cord is a crucial part of the central nervous system and travels within the vertebral column. It does not extend down to the tailbone but typically ends at a specific vertebral level.

Step 3: Analyze Each Option

1. Sacrum: This is a bony structure located at the base of the spine, composed of five fused vertebrae.
2. Coccyx: Often referred to as the tailbone, this is located below the sacrum.
3. 5th Lumbar Vertebra: The spinal cord does not extend this low.
4. 2nd Lumbar Vertebra: The spinal cord usually ends around the level of the first or second lumbar vertebra (L1-L2).

Step 4: Verify and Summarize

The spinal cord typically ends at the first or second lumbar vertebra (L1-L2), making the 2nd lumbar vertebra the most accurate choice among the options provided.

Final Answer

The spinal cord ends at the 2nd lumbar vertebrae.
