If you are removing an epithelium from buccal cavity and pharynx, then you are removing

Options

A. Stratified columnar epithelium
B. Non-keratinised epithelium
C. Non-keratinised cuboidal epithelium
D. Keratinised epithelium

Answer

To answer the question, "If you are removing an epithelium from the buccal cavity and pharynx, then you are removing," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Location**: Understand that the buccal cavity (mouth) and pharynx (throat) are areas lined with specific types of epithelial tissue.

2. **Types of Epithelium**: Familiarize yourself with the types of epithelial tissues. The options given are:
- Stratified columnar epithelium
- Non-keratinized epithelium
- Non-keratinized cuboidal epithelium
- Keratinized epithelium

3. **Characteristics of Epithelia**:
- **Stratified Columnar Epithelium**: Typically found in areas such as the male urethra and some glands, not in the buccal cavity or pharynx.
- **Non-Keratinized Epithelium**: This type is moist and is found in areas that require protection but also need to remain flexible, such as the buccal cavity and pharynx.
- **Non-Keratinized Cuboidal Epithelium**: This type is not typically found in the buccal cavity or pharynx.
- **Keratinized Epithelium**: This type is found in areas subject to abrasion, such as the skin, but is not predominant in the buccal cavity or pharynx.

4. **Conclusion**: Since the buccal cavity and pharynx are lined with non-keratinized epithelium, the correct answer is that you are removing **non-keratinized epithelium**.

5. **Specific Type**: More specifically, this non-keratinized epithelium is classified as **stratified squamous epithelium**, which is designed to protect underlying tissues in areas subject to abrasion.

### Final Answer:
You are removing **non-keratinized epithelium** from the buccal cavity and pharynx.
