MICROANATOMY

Detailed explanation-1: -Hairless skin found in the palms of the hands and soles of the feet is thickest because the epidermis contains an extra layer, the stratum lucidum.

Detailed explanation-2: -The epidermis varies in thickness throughout your body. In areas of skin that experience a lot of use, like the soles of your feet and the palms of your hands, the epidermis is thicker. These areas can be as thick as 1.5 millimeters, which is about as thick as two credit cards stacked together.

Detailed explanation-3: -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-4: -There are five morphologically distinct layers of the soles and palms, with the stratum basale being the deepest, followed sequentially by the stratum spinosum, stratum granulosum, stratum lucidium, and the outer-most protective layer, the stratum corneum.
