Back

Flexion is a movement that decreases the angle between two body parts, typically at a joint.

Front

Separates muscle from surrounding tissues

Back

Epimysium is a connective tissue that surrounds the entire muscle, separating it from surrounding tissues.

Front

What attaches a muscle to the bone?

Back

Tendons are strong connective tissues that attach muscles to bones, allowing for movement.

Front

Surrounds muscle fiber bundles (fascicles)

Back

Perimysium is the connective tissue that surrounds bundles of muscle fibers, known as fascicles.

Front

Which elbow muscle provides extension of the elbow and originates on the humerus?

Back

The triceps brachii is the muscle responsible for extending the elbow and originates from the humerus.

Front

What is the role of cardiac muscle?

Back

Cardiac muscle is specialized muscle tissue found only in the heart, responsible for pumping blood throughout the body.

Front

What is the connective tissue that surrounds individual muscle fibers?

Back

Endomysium is the delicate connective tissue that surrounds each individual muscle fiber.

Front

What is the difference between isotonic and isometric contractions?

Back

Isotonic contractions involve muscle shortening and movement, while isometric contractions involve muscle tension without changing length.
