What are the three histological distinct areas of the epithelium?
  1. Oral, sulcular, and juctional
  2. Sulcular, juctional, and larynx
  3. Oral, sulcular, and functional
  4. Functional, oral, and larynx
Explanation
Answer: A - The three histological distinct areas of the epithelium are the oral, sulcular, and juctional epithelium. The oral epithelium is a continuous lining of attached gingiva. It is composed of keratinized stratified squamous epithelium. The sulcular epithelium exists on the secular side of free gingival; it is nonkeratinized. The juctional epithelium is attached to the tooth by hemidesmosomes at the sulcus of the sulcular epithelium. The cells are large and nonkeratinized.
