Both cardiac muscle fibers and skeletal muscle fibers are striated. d. Skeletal muscle fibers exhibit branching while cardiac muscle fibers do not. 10. Which one of the following statements regarding muscle tissue is false? Cardiac muscle fibers are branched. Skeletal muscle fibers are long and multi-nucleated. Both cardiac muscle fibers and skeletal muscle fibers are striated. Smooth muscle fibers exhibit striations a. b. c. d.

Explanation / Answer

Answer:

6). A. Epithelial

Explanation:

Epithelial tissue covers the body surface, forms glands, and forms the lining for most of the internal cavities. Its functions include: Protection, secretion, absorption, filtration, excretion and sensation.

7). A. Epithelial

Explanation:

Glands are secretory tissues and organs that are derived from epithelial tissues.

8). C. Cardiac muscle

Explanation:

Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected byintercalated discs to work as a single functional organ or syncytium.

9). C. Both cardiac muscle fibers and skeletal muscle fibers are striated

Explanation:

Both Cardiac and skeletal muscle are striated. Cardiac nuclei are centrally placed whereas skeletal nuclei are eccentrally placed. Cardiac muscle fibres are more highly branched than skeletal muscle fibres.

10). D. Smooth muscle fibers exhibit striations

Explanation: Smooth muscle fibers do not have striations, so that they are called as smooth muscles.
