Accepted Answer

Elastic connective tissue

Question 15

A histology slide shows cells in a single layer, all touching the basement membrane, but nuclei are at different heights, giving a stratified appearance. What type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 16

Which of the following is a function of the cutaneous membrane (skin) that is directly related to its keratinized stratified squamous epithelium?
