Front

What is skeletal muscle?

Back

Skeletal muscle is voluntary muscle that moves the body by pulling on bones of the skeleton.

Front

Where is cardiac muscle found and what is its function?

Front

What are the functions of skeletal muscle tissue?

Back

Movement, posture maintenance, support, guarding entrances and exits, temperature regulation, and nutrient reserves.

Front

What is the structure of skeletal muscle?

Back

Skeletal muscle is composed of muscle fibers, connective tissues, blood vessels, and nerves.

Front

What are muscle fibers?

Back

Muscle fibers are the contractile units of skeletal muscle, made up of bundles of myofibrils.

Front

What is the role of connective tissues in skeletal muscle?

Back

Connective tissues support and protect muscle fibers.

Front

What is the epimysium?

Back

The epimysium is a dense layer of collagen fibers that surrounds the entire muscle, separating it from surrounding tissues.

Front

What is the perimysium?

Back

The perimysium is a fibrous layer that divides the muscle into bundles called fascicles, containing blood vessels and nerves.
