2 Fill in the blanks: All tissues consist of two main components: and and which consists of a gelatinous substance called numerous different 3 An epithelial tissue that has one layer of rectangular cells would be classified as a. stratified squamous epithelium. b. simple cuboidal epithelium. c stratified columnar epithelium d. simple columnar epithelium. How do pseudostratified ciliated columnar epithelium and transitional epithelium differ from other types of epithelia? 4 5 True/False: Mark the following statements concerning connective tissue proper and cartilage as true () or false (F). If the statement is false, correct it to make it a true statement. Adipocytes contain a large lipid droplet in their cytoplasm The primary element in dense regular collagenous connective tissue is ground substance Bundles of collagen fibers are arranged paralel to one another in dense irregular collagenous connective tissue. Loose connective tissue contains all three protein fiber types. Fibrocartilage has a smooth, glassy appearance due to a large amount of ground substance and few visible protein fibers Which of the following best characterizes the extracellular matrix (ECM) of bone tissue? a. Bone tissue ECM consists of only calcium hydroxyapatite crystals b. Bone tissue ECM consists of calcium hydroxyapatite crystals and collagen fibers. c. Bone tissue ECM consists of only collagen fibers. d. Bone tissue ECM consists of collagen, elastic, and reticular fibers 6 7 Circle all that apply Which of the following characteristics apply to skeletal muscle tissue? a. Striatec b. Nonstriated C. Multinucleate. d. Uninucleate e. Contains intercalated discs f. Voluntary 9 Involuntary

Explanation / Answer

2. A tissue consist of two main components namely the cytoplasm and the extracellular matrix. The cytoplasm is gelatinous in nature and has different cell organelles.

3. A simple columnar epithelium would be epithelial tissue with one layer of rectangular cells.

4. Pseudostratified columnar epithelium cells are falsely-stratified single layer of epithelial cells which are found in trachea and upper respiratory tract whereas transitional epithelium has multiple layers of epithelial cells which can contract and expand. Both these epithelial cells are the modified form of epithelial cells and form varied functions.

6. Extracelluar matrix of bone tissue is made of collagen, elastin and reticular fibers.
