Pseudostratified ciliated columnar epithelium of the trachea Single layer of cells of differing heights‚ some not reaching the apical surface‚ nuclei located at different levels give the appearance of a mulitlayerd (stratified) tissue. Mucous secreting goblet cells are common in this tissue. There are both ciliated and non-cilated types. Stratified squamous epithelium (non-keratinized) of the esophagus Distinguished by multiple layers of cells with nuclei distributed throughout‚ basal cells are cuboidal

Tissues Tissues are sets of the same cells carrying out particular functions these include; epithelial‚ connective‚ muscle and nervous. Epithelial tissues are the inside layer of internal and external surfaces and body cavities‚ including ducts carrying secretions from glands. They may be composed of some layers of cells‚ called compound epithelia or just a single layer which is known as simple epithelia. The lowest or bottom layer of cells is attached to the basement membrane for support and

Chapter 5 Study Guide Name: Hour: 1. What are the five most important functions of epithelial tissue. 2. Identify the four principal tissue types. 3. Explain how the shape of epithelial cells is used for classification purposes. What are the four types of epithelium described in this classification process? 4. Classify epithelium according to the layers of cells present. 5. List the types of simple and stratified epithelium and give examples of each

affects the patients connective tissue. The name means “soft connective tissue that progressively turns to bone.” FOP is a result of a mutation in the body’s tissue repair structures‚ which will cause fibrous tissue to turn to bone‚ or become ossified‚ randomly or upon tissue damage. In the majority of cases‚ any injury can cause the affected joints to become frozen in place indefinitely. Removal of the newly ossified tissue is counterproductive‚ as the attempt at repairing the tissue will simply signal

the pulp: fibrous changes pulpal stones –diffuse calcifications) DEFINITION : The pulp is a delicate mesenchymal connective tissue that occupies the pulp cavity in the central part of tooth. The normal pulp is pink‚ coherent soft tissue is noted‚ dependent on its normal hard dentin for protection. Dentin and pulp are embryologically‚ histologically‚ and functionally the same tissue and therefore are considered as a complex. Both dentin and pulp have a common origin from the dental papilla It

Marfan’s Syndrome Marfan syndrome is an inherited connective-tissue disorder transmitted as an autosomal dominant trait. It is distributed worldwide‚ has a high prevalence rate and has pleiotropic manifestations‚ meaning one gene influences multiple traits that do not seem to be related. Mutations of the FBN1 gene on the 15th chromosome (more specifically chromosome 15q21.1) cause Marfan syndrome. The FBN1 gene is coded to make a glycoprotein called fibrillin-1
