Epithelial cells have two surfaces that differ in both structure and function. Glands Lines the bladder, urethra and ureters, Allows the urinary organs to expand and stretch Stratified epithelia can be columnar, cuboidal, or squamous type. Epithelial cells derive from all three major embryonic layers. . Transitional describes a form of specialized stratified epithelium in which the shape of the cells can more stretched out and less stratified when the bladder is full and distended. Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle Transitional epithelium has cells that can change from squamous to cuboidal, depending on the amount of tension on the epithelium. is relaxed, or stratified squamous when the organ is distended and the tissue stretches.
A single organ can have different types of epithelial tissue based on the a special subset of stratified epithelia that consist of ovoid cells that can stretch based. I. Epithelial Tissue. A. Common Characteristics 1) Individual cells are closely attached to each other at their margins to form tight sheets 2) No extra-cellular. Types of tissues in the body Learn with flashcards, games, and more — for free. Epithelial cells that can change shape when stretched. Transitional. Avascular.
Specialized Contacts: except for glandular epithelia, epithelial cells fit closely laminae form; reinforces the epithelial sheet, helps it resist stretching, tearing and two basic parts, can be classified by structure and by the type of secretion. They also are able to stretch so you can move your fingers and arms into many positions. You can also thank your epithelial cells for making the sweat that cools . This type of epithelium contains goblet cells, microvila, and cilia. Where do you find transitional epithelium tissue in the body? It makes up the This type of fiber allows tissues to return to their original length after being stretched. Elastic. Epithelia can be specialized to perform additional functions such as Stratified squamous epithelium: the cells originate from a layer of cells along a basal lamina This type of epithelium lines the respiratory tract from the nasopharynx down into the The cells are connected in a way that allows stretching and expansion.
