Front

What type of muscle is found in your heart?

Back

Cardiac muscle is the type of muscle found in the heart, responsible for pumping blood throughout the body.

Front

What are the structures located at the ends of a sarcomere?

Back

The ends of a sarcomere are marked by Z lines, which define the boundaries of each sarcomere.

Front

What type of muscle has no stripes (striations)?

Back

Smooth muscle has no stripes (striations) and is found in the walls of hollow organs.

Front

What are the three layers of muscle tissue?

Back

The three layers of muscle tissue are Epimysium, Perimysium, and Endomysium.

Front

What is the function of tendons in the muscular system?

Back

Tendons connect muscles to bones, allowing for movement when muscles contract.

Front

What is flexion in terms of muscle movement?

Back

Flexion is a movement that decreases the angle between two body parts, such as bending the elbow.

Front

What is the primary function of skeletal muscle?

Back

The primary function of skeletal muscle is to facilitate voluntary movement of the body.

Front

What type of muscle is involuntary and found in the walls of organs?

Back

Smooth muscle is involuntary and found in the walls of hollow organs, such as the intestines.

Front

What is the role of the sarcomere in muscle contraction?

Back

The sarcomere is the basic contracting unit of muscle tissue, where the actin and myosin filaments slide past each other to produce contraction.

Front

What is the difference between voluntary and involuntary muscles?

Back

Voluntary muscles are controlled consciously (e.g., skeletal muscles), while involuntary muscles operate automatically (e.g., cardiac and smooth muscles).
