Olfactory Epithelium (Scheneidarian membrane) is composed of : -

Options

A. Neuro sensory Epitheelium
B. Simple sq. Epithelium
C. Simple cuboidal
D. Germinal Epithelium

Answer

### Step-by-Step Solution:

1. **Understanding Olfactory Epithelium**: The olfactory epithelium, also known as the Schneiderian membrane, is a specialized tissue located in the nasal cavity that is responsible for the sense of smell.

2. **Identifying the Composition**: The question asks about the composition of the olfactory epithelium. We need to evaluate the given options to determine which type of epithelium makes up this structure.

3. **Evaluating the Options**:
- **Option 1: Neurosensory Epithelium**: This type of epithelium is specialized for sensory functions, including the detection of smell. It contains olfactory sensory neurons that transmit smell information to the brain.
- **Option 2: Simple Squamous Epithelium**: This type of epithelium is thin and flat, typically found in areas where diffusion occurs, such as in the alveoli of the lungs. It is not specialized for smell.
- **Option 3: Simple Cuboidal Epithelium**: This type of epithelium is found in glands and ducts, and it is not involved in the sensory function of smell.
- **Option 4: Germinal Epithelium**: This type of epithelium is involved in the production of gametes and is not related to the olfactory function.

4. **Conclusion**: Based on the evaluation, the olfactory epithelium is primarily composed of **Neurosensory Epithelium** (Option 1), which is responsible for the sensory function of detecting odors and transmitting that information to the brain.

5. **Final Answer**: The correct answer is **Option 1: Neurosensory Epithelium**.
