Question

which statement best describes the differences between thick and thin skin?
a.) thick skin has 4 layers of keratinized, stratified squamous epithelium, layers of fat in between the epithelial layers, and can be found only on the palms of the hand and the soles of the feet.
b.) thick skin has 5 layers of keratinized, stratified squamous epithelium and can be found only on the palms of the hand and the soles of the feet.
c.) thick skin has 5 layers of keratinized, stratified squamous epithelium and can be found only on the knees and back of the elbows.

Explanation:

Thick skin has five layers of keratinized, stratified squamous epithelium (stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale). It lacks hair follicles and sebaceous glands. It is found on the palms of the hands and soles of the feet. Thin skin has four layers (lacks stratum lucidum) and is found over most of the body. Option a is incorrect as thick skin has 5 layers, not 4. Option c is incorrect as thick skin is not on knees and back of elbows (those areas have thin skin).

Answer:

B. Thick skin has 5 layers of keratinized, stratified squamous epithelium and can be found only on the palms of the hand and the soles of the feet.
