Inner wall of urinary bladder is composed of

Options

A. Unstriped muscles
B. Striped muscles
C. Stratified epithelium
D. Tranisitional epithelium

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of the Urinary Bladder**:
- The urinary bladder is a hollow organ that serves as a storage site for urine. Its inner wall is specifically designed to accommodate the stretching that occurs as it fills with urine.

2. **Identifying the Layers of the Urinary Bladder**:
- The bladder wall consists of several layers, including muscle layers and epithelial layers. The inner layer is crucial for its function.

3. **Examining the Options**:
- The options provided are:
- a) Unstripped muscles
- b) Stripped muscles
- c) Stratified epithelium
- d) Transitional epithelium

4. **Analyzing Each Option**:
- **Unstripped Muscles**: These are smooth muscles found in various organs, but they do not form the innermost layer of the bladder.
- **Stripped Muscles**: These refer to skeletal muscles, which are not present in the bladder wall.
- **Stratified Epithelium**: This type of epithelium is found in areas subject to abrasion, but it is not the primary type in the bladder.
- **Transitional Epithelium**: This specialized epithelium is designed to stretch and is found lining the inner surface of the urinary bladder.

5. **Conclusion**:
- The inner wall of the urinary bladder is composed of **Transitional Epithelium**. This epithelium allows the bladder to expand and contract as it fills and empties.

### Final Answer:
The inner wall of the urinary bladder is composed of **Transitional Epithelium**.
