The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Transitional Epithelium**: Transitional epithelium is a specialized type of epithelial tissue that is primarily found in the urinary system, including the urinary bladder, ureters, and urethra. Its unique structure allows it to stretch and accommodate fluctuations in the volume of liquid in these organs. 2. **Identifying the Layers**: The transitional epithelium consists of multiple layers of cells. The innermost layer is crucial for identifying the type of cells present. 3. **Analyzing the Options**: - **Option 1**: "Innermost layer is cuboidal, rests on an underlying connective tissue." This option suggests that the innermost layer consists of cuboidal cells, which is consistent with the structure of transitional epithelium. - **Option 2**: "Innermost layer is columnar, rests on underlying connective tissue." Columnar cells are typically found in other epithelial types, such as those lining the digestive tract, not in transitional epithelium. - **Option 3**: "Innermost layer is pear-shaped, rests on basement membrane." Pear-shaped cells are not characteristic of transitional epithelium. - **Option 4**: "Innermost layer is umbrella-shaped, rests on underlying basement membrane." While transitional epithelium does have umbrella cells on the surface, the question specifically asks about the innermost layer, which is not umbrella-shaped. 4. **Selecting the Correct Answer**: Based on the analysis, the correct answer is that the "innermost layer is cuboidal, rests on underlying connective tissue." This aligns with the known structure of transitional epithelium. 5. **Conclusion**: The transitional epithelium's innermost layer is cuboidal, which allows it to effectively function in the urinary system. ---
