Epithelium forming the inner layer of urinary bladder is

Options

A. Simple squamous
B. Transitional
C. Simple columnar
D. Neurosensory.

Answer

**Step-by-Step Text Solution:**

1. **Understanding Epithelium**: Epithelium is a type of tissue that forms protective layers on body surfaces and lines cavities and organs. It plays a crucial role in protection, absorption, secretion, and sensation.

2. **Identifying the Structure**: The urinary bladder is a sac-like organ that temporarily stores urine. Its ability to stretch and contract is essential for its function.

3. **Type of Epithelium in the Urinary Bladder**: The inner layer of the urinary bladder is composed of transitional epithelium. This type of epithelium is unique because it can change shape and size.

4. **Function of Transitional Epithelium**: Transitional epithelium allows the bladder to expand when it fills with urine and contract when it is emptied. This adaptability is crucial for the bladder's function in urine storage and expulsion.

5. **Excluding Other Types of Epithelium**: Other types of epithelium, such as simple squamous and simple columnar, do not have the necessary properties to accommodate the bladder's function. Therefore, they are not present in the inner layer of the urinary bladder.

6. **Conclusion**: The correct answer to the question is that the epithelium forming the inner layer of the urinary bladder is transitional epithelium.
