Chapter 41, Problem 4U
Summary Introduction
Introduction:
Skeletal muscle cells are arranged in bundles tied together by connective tissues and anchored at both the ends by tendons to bones and other supporting tissues. These muscles are very long, cylindrical and multinucleated. The striation reflects the regular pattern of distribution of the filaments inside the cells and multiple nuclei is located on the periphery of the cells.

Interestingly, shellfish such as clams can maintain a month-long contraction in the muscle that keeps the shell closed. No oxygen gets in this situation. These muscles have a different version of myosin called paramyosin. Knowing what you know about the cellular mechanism of muscle contraction, propose a hypothesis to explain how paramyosin might work.arrow_forward
