A: The Sarcomere is a large protein unit that is essential for contraction in the muscle. Both skeletal…

Q: What are sarcomeres?

A: Myofibrils are composed of bundles of protein filaments known as myofilaments.

Q: Is the sarcomere in Figure 12.5 fully contracted? Explain.

Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.
