The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Structure**: The question asks about the enlargement at one end of each semicircular canal. The semicircular canals are part of the inner ear and play a crucial role in balance and spatial orientation. 2. **Identifying the Enlargement**: The specific enlargement at one end of each semicircular canal is known as the ampulla. This is a key anatomical feature of the semicircular canals. 3. **Function of the Ampulla**: The ampulla contains specialized structures that are important for detecting rotational movements of the head. It houses the crista ampullaris, which contains hair cells that respond to fluid movement. 4. **Fluid in the Ampulla**: The ampulla is filled with a fluid called endolymph, which is essential for the functioning of the hair cells within the ampulla. 5. **Conclusion**: Therefore, the enlargement at one end of each semicircular canal is referred to as the ampulla. **Final Answer**: The enlargement at one end of each semicircular canal is known as the **ampulla**. ---
