Stratified squamous epithelium covers moist surfaces like buccal cavity

Answer

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

1. **Understanding Stratified Squamous Epithelium**:
- Stratified squamous epithelium is a type of epithelial tissue made up of multiple layers of flattened (squamous) cells.
- It is designed to provide protection against abrasion, desiccation (drying out), and other environmental factors.

2. **Structure of Stratified Squamous Epithelium**:
- This epithelium consists of several layers of cells. The bottom layer is in contact with the basement membrane, while the upper layers adhere to each other.
- The arrangement of these layers helps maintain the structural integrity of the tissue.

3. **Location and Function**:
- Stratified squamous epithelium is found in areas of the body that are exposed to friction and abrasion, such as the skin, esophagus, and oral cavity (buccal cavity).
- In the buccal cavity, this epithelium protects underlying tissues from mechanical damage and helps retain moisture.

4. **Moist Surfaces**:
- The oral cavity is lined with mucous membranes, which contain stratified squamous epithelium.
- This epithelium may be keratinized (having a layer of keratin for added protection) or non-keratinized, depending on the specific location and function.

5. **Mucus Production**:
- The surface of the buccal cavity is kept moist by mucus, which is secreted by salivary glands. This moisture is crucial for oral health and function.

6. **Conclusion**:
- Given the characteristics and functions of stratified squamous epithelium, the statement that "stratified squamous epithelium covers moist surfaces like the buccal cavity" is indeed true.

**Final Answer**: True
