Chapter 6: Integumentary System

lies beneath the dermis. The subcutaneous layer is composed of areolar tissue and adipose tissue that helps conserve body heat. This layer contains blood vessels that supply the skin. * Epidermis * The epidermis is stratified squamous epithelium that lacks blood vessels. * The deepest layer, called the stratum basale, contains cells that divide and grow. * Epidermal cells undergo keratinization as they are pushed toward the surface. * The outermost layer, called the...

Epithelium Tissue

Epithelial Tissue covers body surfaces (epi, on + thelium, surface). Epithelial tissue consists of cells attached to one another to form an uninterrupted layer of cells that separates the underlying tissues from the outside world. The body's epithelium not only covers its obvious surfaces (such as the epidermis of the skin and the linings of respiratory, urinary, and digestive tracts) but also extends into all of the complex invaginations which form lungs, kidneys, sweat glands, digestive glands...

Bladder Cancer

BLADDER CANCER Bladder cancer is the growth of malignant cells in the urinary bladder. Most forms of bladder cancer start in the superficial layer of the transitional epithelium, and most often affect the transitional cells. It may also be called transitional cell carcinoma or even urothelial carcinoma. Urothelial carcinoma is also a term used for transitional cell cancer in the renal pelvis, ureters, and urethra. Bladder cancer is a relatively common disease. It is the fourth leading cancer...

have simple squamous epithelium and other areas have stratified squamous epithelium? Stratified squamous epithelium is used in areas of the body that undergo more abrasion (Epithelial Cells) than then areas of the body that require just having simple squamous epithelium (Epithelial Cells). Examples of areas that need stratifies squamous epithelium are the outmost layer of skin as well as the lining of the mouth and esophagus. In contrast, areas that use simple squamous epithelium include capillaries...

the squamous epithelium; goblet cell hyperplasia, inflammation and squamous metaplasia of the respiratory epithelium; also hyaline degeneration of the olfactory epithelium were observed. The nasal lesions of the mice were qualitatively similar to the nasal lesions of the rats that were exposed. Squamous metaplasia of the respiratory epithelium was observed in both sexes of mice whereas female mice also had inflammation and hyaline degeneration of the respiratory epithelium. No neoplastic...

Epithelial tissue types

Stratified squamous: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Although this epithelium is referred to as squamous, many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface. In the deeper layers, the cells may be columnar or cuboidal. This type of epithelium is well suited to areas in the body subject to constant abrasion, as it...

The melanin makes the body become darker or tanner and when the body is darker the more protected it is from the sun and sunburn. B. Describe the functions of the epidermis. The epidermis is the outermost layer that has keratinized squamous epithelium and the dermis. The epidermis has a bunch of different cells which allow it to perform many different functions. The keratinocytes produce keratin that produce fibrous protein that gives skin protective properties while the melanocytes produce...
