What function do keratinized and nonkeratinized stratified squamous epithelia have in common? what is the structural difference between these two? how is this structural difference related to a functional difference between them?

(Question 1 points 3)

The keratinized stratified squamous epithelia and non-keratinized stratified squamous epithelia are the two main categories of epithelia tissues. They both are certified for different functions based on their position and presence of keratin on them. The main function of epithelial tissues either the keratinized stratified squamous epithelia or the non-keratinized stratified squamous epithelia is to protect the underlying tissues any sort of infection, physical damage, desiccation heat loss, and UV radiations.

(Question 2 points 3)

1. keratinized epithelium forms the epidermis of land vertebrates, while the non-keratinized epithelium forms the lining of the esophagus, buccal cavity, and the pharynx.

2. keratinized epithelium provides better protection, while the non-keratinized epithelium provides moderate protection.

3. The keratinized epithelium is impenetrable for water, while the non-keratinized epithelium is penetrable for water.

4. keratinized epithelium have the keratin but keratin is absent in the non-keratinized epithelium.

5. keratinized epithelium have dead surface cells while the non-keratinized epithelium has living surface cells.

(Question 3 points 3)

keratins are the structural proteins that are present in keratinized epithelium but not in non-keratinized epithelium which is the main difference between both of them for their functions because keratin proteins are responsible for the formation of intermediate filament networks. In this way, they provide the structural integrity to the keratinized epithelium but not to the non-keratinized epithelium just because of the absence of keratins (a diverse group of proteins).
