Question

The cells of which layer contain droplets of eleidin.
A. Stratum lucidum
B. Stratum granulosum
C. Stratum corneum
D. Stratum spinosum

Answer 1

Hint: The hypodermis is the thickest and innermost (or deepest) layer of skin. The subcutaneous layer, or subcutaneous tissue, is another name for it. The epidermis (the outermost layer), dermis (the next layer, which is densely packed with blood vessels and nerves), and hypodermis (the third layer) are the layers of the skin.

Complete answer:
The layer of Stratum lucidum is thicker on the palms and soles. Several rows of transparent, flat, and dead cells make up the layer. It contains eleidin droplets, which are a transparent material.

Three to five rows of flattened cells with keratohyalin as a material are detected in the stratum granulosum. Twenty-five to thirty rows of flat, dead cells that are entirely packed with keratin make up the stratum corneum.

This layer of the epidermis is made up of eight to ten rows of polyhedral cells that fit tightly together in Stratum spinosum.

As a result, option A is the correct answer.

The dead and flattened keratinocytes that make up the stratum lucidum. These cells are tightly packed with eleiden, a lipid-rich clear protein generated from keratohyalin that gives them their translucent (i.e., lucid) look and acts as a water barrier.

Between the stratum granulosum and stratum corneum layers, a fifth layer (stratum lucidum) is sometimes detected in thick skin. It's a thin, transparent layer that's difficult to spot in histological sections.

Note:-
Keratinocytes are the most common cell type in the epidermis, and they play a variety of roles in skin restoration. They carry out the re-epithelialization process, which involves keratinocytes migrating, proliferating, and differentiating in order to re-establish the epidermal barrier.
