Problem:
The image below shows a longitudinal view of a type of muscle. Note the multiple nuclei that lie at the periphery of the muscle fibers as well as the striations (thin lines) formed by the arrangement of the thick and thin myofilaments. It is the arrangement of these myofilaments that results in the A bands, I bands and Z lines that run perpendicular to the long axis of the myofibrils.
1. What are the characteristics of muscle tissue?
2. What type muscle tissue is this?
3. Is this type muscle voluntary or involuntary?
Additional Information:
These short answer questions is from Biology. The questions 1 and 2 discuss about the functions of muscle tissue and to determine the type of muscle tissues in picture above.
