GENERAL HISTOLOGY

Detailed explanation-1: -Stratum lucidum, 2-3 cell layers, present in thicker skin found in the palms and soles, is a thin clear layer consisting of eleidin which is a transformation product of keratohyalin.

Detailed explanation-2: -The stratum lucidum layer is only present in the thicker skin of the palms and soles. Its main function is to reduce friction between the stratum corneum and stratum granulosum. The name itself comes from the Latin for “clear layer, ” which describes the transparency of the cells themselves.

Detailed explanation-3: -Its presence indicates the importance of having thicker skin to protect against frequent exposure to mechanical stress. The stratum lucidum is found in in between the stratum corneum and the stratum granulosum. The keratinocytes are filled with eleidin (a protein that may be later converted to keratin).
