Which statement regarding striated muscle is correct?

• A. It forms the major muscle mass of the body and usually crosses at least one joint
• B. It is attached directly to the bones by tough bands of cartilage
• C. Most of the body's striated muscle is found within the walls of blood vessels
• D. Striated muscle is involuntary

Answer: (A)

Striated muscle, also known as skeletal muscle, is primarily responsible for the movement of the skeleton and is characterized by its striped appearance under a microscope. The correct statement indicates that striated muscle forms the major muscle mass of the body and typically crosses at least one joint. This is significant because it enables skeletal muscles to exert force and contribute to a wide range of movements, such as walking, lifting, and other motor activities. The fact that striated muscle usually crosses at least one joint is crucial for its function. When a muscle contracts, it pulls on the bone to which it is attached, effectively creating movement at the joint. This characteristic is fundamental in the study of human anatomy and physiology, as it emphasizes the relationship between muscle action and joint movement. Contrasting this with the other options, it is important to note that striated muscle does not attach directly to bones by cartilage; instead, it connects to bones via tendons. Additionally, striated muscle is not primarily found in the walls of blood vessels. Smooth muscle, another type of muscle tissue, is responsible for involuntary movements in the walls of blood vessels. Lastly, while striated muscle generally refers to voluntary muscle that we consciously control, there are instances
