Question

A researcher is examining a sample of skeletal muscle under a microscope. Which of the following would correctly describe what she is seeing? (2 points) Single nucleus per cell, non-striated, short cells Single nucleus per cell, striated, branching cells Multinucleated, non-striated, branching cells Multinucleated, striated, elongated and threadlike cells

Answer 1

The skeletal muscle is a type of striated muscle attached to the skeleton. Formed by cells or elongated and multinucleated fibers that place their nuclei in the periphery. They obey the organization of actin and myosin proteins and give them that striation that is perfectly seen under a microscope. The human body is composed of approximately 40% of this type of muscle and 10% of cardiac and visceral muscle.Skeletal muscles are the main muscles of the human body, which make up a large part of muscle mass. Thanks to the skeletal muscles, the body stays in position, the joints are stable, movements are made and energy is produced by contractions of variable intensity.For the above, if the researcher is examining a skeletal muscle sample under a microscope, the answer that correctly describes what he is seeing is Multinucleated, striated, elongated and threadlike cells.
