Detailed explanation-1: -The stratum lucidum is a smooth, seemingly translucent layer of the epidermis located just above the stratum granulosum and below the stratum corneum. This thin layer of cells is found only in the thick skin of the palms, soles, and digits.

Detailed explanation-2: -The stratum lucidum is the only layer found in thick skin that is not found in the other skin layers.

Detailed explanation-3: -Thick skin does have an extra epidermal layer called the stratum lucidum, which is absent in thin skin. The function of thick skin is mainly to prevent damage due to abrasion and friction. The thin skin also functions in protection, but also produces hairs, sweat, and sebum.
