Question: Check all of the statements that are true regarding keratinized stratified squamous epithelium.

1. Keratinized stratified squamous epithelium is typically found lining the oral cavity. 2. Keratinized stratified squamous epithelium forms the epidermis of the skin. 3. In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

Answer: (2) Keratinized stratified squamous epithelium forms the epidermis of the skin; (3) In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead.

1. Keratinized stratified squamous epithelium is typically found lining the oral cavity - False.

Most of the oral cavity consists of nonkeratinsed superficial layer of stratified squamous epithelium. Non-keratinized stratified squamous epithelia lines the oral cavity, pharynx, esophagus, and anus.

2. Keratinized stratified squamous epithelium forms the epidermis of the skin - True.

In land vertebrates, keratinized stratified squamous epithelium forms the epidermis of the skin. On exposed body surfaces, the apical (outer) layers of the epithelial cells are packed with large numbers of keratin filaments. The keratinized epithelium is tough and water resistant which prevents loss of water and mechnaical injury. The cells on the apical (outer) surface are dead beacause they are keratinized.

3. In keratinized stratified squamous epithelial tissue, the cells on the apical (outer) surface are dead - True.
