Epithelial cell membranes have three regions (domains) different in structure and function; apical, lateral and basal. The directional term that means "closest to the point of attachment to the trunk" is. stratified squamou, Which of these is not a type of epithelial tissue?a. Tissues chapter 5 Flashcards | Quizlet They have an organelle rich cytoplasm. Desmosomes hold neighboring cells together by way of cadherin molecules which are embedded in protein plates in the cell membranes and link together between the adjacent cells. A. Epithelial tissues are characterized by shapes of cells and how many layers of cells are present in the tissue B. Epithelial tissues have polarity. A gland is a structure made up of one or more cells modified to synthesize and secrete chemical substances. 1. epithelial tissue lacks blood vessels. Palms are facing forward. Kim Bengochea, Regis University, Denver. It lines the excretory ducts of the sweat glands, large ducts of excretory glands, the anorectal junction and surrounds ovarian follicles. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. Which of the tissues would you expect to be most affected? How would you interpret your observation? In contrast, the process of holocrine secretion involves the rupture and destruction of the entire gland cell. blood vessels) and cornea. Epithelia specialized for protection, such as the stratified squamous keratinized epithelium of the skin, are multilayered and have a high cell renewal rate. Almost done! ___ exocrine gland a. strong, pliable; like rubber ___ endocrine gland b. secretion through duct ___ cartilage c. deep skin layer ___ dermis d. contracts, not striated ___ smooth muscle e. assist and support neurons ___ bone f. makes skin dark ___ melanin g. lines lungs ___ blood h. cells in a hardened matrix ___ neuroglia i. fluid connective tissue ___ brown fat j. ductless secretion ___ simple squamous epithelium k. many mitochondria produce heat, Please list different types of glands and different purposes for them, Untitled Section Choose the correct answer The study of epithelial tissues structure, functions, and associated structures reveals the following: * O Lateral surface specializations include zonula adherens which lies subjacent to the gap junction Epidermis and mucosal epithelia are barriers that protect the body against the environment Glycocalyx occurs at epithelial surfaces facing the lumen and represent an apical surface specializations Connexons are protein units form hexamers with hydrophilic pores 1.5 nm in diameter.
