Kidney located at the level of

Options

A. 12th thoracic and 3rd lumbar
B. Last thoracic and 3rd sacral
C. 12th thoracic and 2nd sacral
D. 2nd thoracic and 3rd lumbar

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the anatomical location of the kidneys in relation to the vertebral column.

2. **Know the Vertebral Levels**: The human spine consists of different sections: cervical, thoracic, lumbar, sacral, and coccygeal. The thoracic section has 12 vertebrae (T1 to T12) and the lumbar section has 5 vertebrae (L1 to L5).

3. **Identify the Options**: The options given are:
- A) 12th thoracic and 3rd lumbar vertebra
- B) Last thoracic and 3rd sacral
- C) 12th thoracic and 2nd sacral
- D) 2nd thoracic and 3rd lumbar

4. **Locate the Kidneys**: The kidneys are typically located between the 12th thoracic vertebra (T12) and the 3rd lumbar vertebra (L3). This means that they are positioned at the level of the last thoracic vertebra and the first few lumbar vertebrae.

5. **Evaluate the Options**:
- Option A states the kidneys are at the 12th thoracic and 3rd lumbar vertebra, which is correct.
- Option B mentions the last thoracic and 3rd sacral, which is incorrect.
- Option C states the 12th thoracic and 2nd sacral, which is also incorrect.
- Option D states the 2nd thoracic and 3rd lumbar, which is incorrect.

6. **Conclusion**: Based on the anatomical positioning of the kidneys, the correct answer is Option A: 12th thoracic and 3rd lumbar vertebra.

**Final Answer**: Option A
