Which of the following types of junctions in an epithelium a
Which of the following types of junctions in an epithelium allows the tissue to stretch and bend, as in the epithelium of the skin? Select one: a. adhesion junction b. stratified junction c. gap junction d. glandular junction e. tight junction The evolution of multicellular organisms confers all of the advantages EXCEPT Select one: a. the larger size of multicellular organisms helps them survive. b. tissues of a multicellular organism are integrated. c. the cells of a multicellular organism work collectively to perform life functions. d. cells of a multicellular organism are very similar and are rarely specialized. e. allows for specialization of cells. Which of the following membranes line s the airways and digestive tract? Select one: a. serous b. mucous c. membranous d. synovial e. The stability of a synovial joint is due largely to the presence of tendons and ligaments. Select one: True False
Solution
Answer:
1). a. Adhesion junction
Adhesion junctions is looser in structure than tight junctions and allow for some movement between cells so that the tissues can stretch and bend.
2). d. cells of multicellular organism are very similar and are rarely specialized
3). b. Mucous
Mucous membrane lines the airways, digestive tract, and reproductive passages. Goblet cells within the epithelial layer secrete mucus, which lubricates the membrane\'s surface and entraps foreign particles.
4). True
Factores that include influence the stability of a synovial joint include the shape of articular surfaces, presence of strong reinforcing ligaments, and tone of surrounding muscles.
