I. Stratified Squamous Epithelium (left side) Flat epithelial tissues which are flat and have more than one layer. The Skin for a barrier. Your skin‚ for example‚ is a formidable barrier against many things. Skin is created when the basal cells in skin are dividing by the process of mitosis and‚ as division takes place‚ the cells get pushed upwards. As a result‚ the newer cells tend to stay near the bottom of the epithelial tissue‚ and the older cells get pushed upward and eventually

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

There are thousands of burn victims awaiting donations of human tissue to help meet critical needs in reconstructive surgery. My current case #49 regards the selling of human tissue donations. It’s a complicated situation where a few medical centers have acquired a partnership with a biotechnological company called Ardias Corporation. Ardias wants to create a tissue bank to help facilitate researchers with disease-specific tissue that will provide a link to accurate genetic sequence with diseases

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 four tissue types found in the human body. Describe an example of each type with their function and location. The four main tissues in the human body are connective‚ epithelium‚ muscle and nervous tissue. Connective tissue is an abundant nonliving extracellular matrix‚ located throughout the human body; such as the head‚ tendons‚ bone‚ and many more. It is the most widespread tissue in the human body and is the most durable tissue type. There are so many functions for this tissue‚ that it
