Question

multiple choice question
which layer of the epidermis is no longer mitotic and contains dark staining clusters of keratohyalin?
stratum basale
stratum granulosum
stratum lucidum
stratum spinosum

Explanation:

The stratum granulosum is the layer of the epidermis that is no longer mitotic (cells no longer divide) and contains dark - staining clusters of keratohyalin. Keratohyalin granules contribute to the formation of keratin in the more superficial layers. The stratum basale is mitotic, the stratum lucidum is mainly present in thick skin and lacks keratohyalin clusters in the described way, and the stratum spinosum is also mitotic and has different characteristics.

Answer:

B. Stratum granulosum
