a type of epithelial cell in the epidermis is a quizlet
EPITHELIUM • epithelium is a tissue composed of a layer of cells.• Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies. • The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities. The epidermis is the uppermost or epithelial layer of the skin. It acts as a physical barrier, preventing loss of water from the body, and preventing entry of substances and organisms into the body. Its thickness varies according to body site. The epidermis consists of stratified squamous epithelium. A. Epidermis. The epidermis is the uppermost or epithelial layer of the skin. It acts as a physical barrier, preventing loss of water from the body, and preventing entry of substances and organisms into the body. Its thickness varies according to body site. The epidermis consists of stratified squamous epithelium. The skin consists of two quite different layers: (1) the epidermis, a superficiallayer of stratified epithelium that develops from ectoderm, and (2) the dermis, or corium, an underlying layer of connective tissue that is largely mesodermal in origin. The epidermis is the uppermost or epithelial layer of the skin. It acts as a physical barrier, preventing loss of water from the body, and preventing entry of substances and organisms into the body.

The skin consists of two quite different layers: (1) the epidermis, a superficiallayer of stratified epithelium that develops from ectoderm, and (2) the dermis, or corium, an underlying layer of connective tissue that is largely mesodermal in origin. The dermis makes up the bulk of the skin. A. Epidermis. The epidermis is the uppermost or epithelial layer of the skin.

The epidermis is the uppermost or epithelial layer of the skin. It acts as a physical barrier, preventing loss of water from the body, and preventing entry of substances and organisms into the body. The epithelium is a layer of cells-epithelial cells. They are highly specialised for selective secretion and absorption of ions and molecules. Epithelial cells line any surface that comes into contact with the external environment. So-the airways, the gut, the urinary tract, the cornea etc.
Stratified squamous.
