    It forms the outermost layer of the skin and the inner lining of the mouth, esophagus and vagina. [2] In the epidermis of skin in mammals, reptiles, and birds, the layer of keratin in the outer layer of the stratified squamous epithelial surface is named the stratum corneum. Stratum corneum is made up of squamous cells which are keratinized and ...

    This structure consists of connective tissue covered by a simple squamous epithelium, called the mesothelium, which reduces frictional forces during digestive movements. The intraperitoneal regions include most of the stomach, first part of the duodenum, all of the small intestine, caecum and appendix, transverse colon, sigmoid colon and rectum ...

    The outermost layer of human skin is composed of dead stratified squamous, keratinized epithelial cells. [14] Tissues that line the inside of the mouth, the esophagus, the vagina, and part of the rectum are composed of nonkeratinized stratified squamous epithelium. Other surfaces that separate body cavities from the outside environment are ...

    The epidermis, "epi" coming from the Greek language meaning "over" or "upon", is the outermost layer of the skin.

    In contrast, the ectocervix is covered with nonkeratinized stratified squamous epithelium, [4] which resembles the squamous epithelium lining the vagina. [17]: 41 The junction between these two types of epithelia is called the squamocolumnar junction. [17]: 408–11 Underlying both types of epithelium is a tough layer of collagen. [18]

    The skin is made up of three microscopic layers: epidermis, dermis, and hypodermis. The epidermis is composed of stratified squamous epithelium and is divided into the following five sublayers or strata, listed in order from outer to inner: Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum,

    Barrett's esophagus is a condition in which there is an abnormal (metaplastic) change in the mucosal cells lining the lower portion of the esophagus, from stratified squamous epithelium to simple columnar epithelium with interspersed goblet cells that are normally present only in the small intestine and large intestine.
