Which of the following statements about epithelial keratinization is accurate?

Show Answers

Non-keratinized epithelium lacks both the stratum granulosum and stratum corneum layers, with surface cells retaining their nuclei.Parakeratinized epithelium features superficial cells containing pyknotic nuclei and does not have a stratum granulosum layer.Orthokeratinized epithelium has a visible stratum granulosum, and its surface cells are anucleate.All the above statements are true.None of the above.

Explanation

Option A is correct because non-keratinized epithelium lacks both stratum granulosum and stratum corneum, with nucleated surface cells. Option B is accurate as parakeratinized epithelium has superficial cells with pyknotic nuclei and no stratum granulosum. Option C is true since orthokeratinized epithelium contains a stratum granulosum, and its superficial cells lose their nuclei. Therefore, all these descriptions are correct.
