What is the epimysium?

Back

The epimysium is the outermost layer of connective tissue that surrounds a skeletal muscle, providing protection and support.

Front

What is the perimysium?

Back

The perimysium is the connective tissue that surrounds individual fascicles (bundles of muscle fibers) within a skeletal muscle.

Front

What is the endomysium?

Back

The endomysium is the innermost layer of connective tissue that surrounds each individual muscle fiber (myofiber) within a fascicle.

Front

What is a sarcomere?

Back

A sarcomere is the basic functional unit of a muscle fiber, responsible for muscle contraction, consisting of actin and myosin filaments.

Front

What is the sarcolemma?

Back

The sarcolemma is the cell membrane of a muscle fiber, which encloses the cytoplasm and regulates the entry and exit of substances.

Front

What is a myofibril?

Back

A myofibril is a long, thread-like structure within a muscle fiber, composed of repeating sarcomeres and responsible for muscle contraction.

Front

What is a myofiber?

Back

A myofiber is a single muscle cell, also known as a muscle fiber, that is capable of contraction.

Front

What is the function of the epimysium?

Back

The epimysium protects muscles from friction against other muscles and bones, and helps to maintain the structure of the muscle.

Front

What is the role of the perimysium in muscle function?

Back

The perimysium provides support and protection to the fascicles, allowing for efficient force transmission during muscle contraction.

Front

How does the endomysium contribute to muscle fiber function?

Back

The endomysium provides a supportive environment for individual muscle fibers, facilitating the exchange of nutrients and waste.
