Which type of muscle is characterized by voluntary control and is responsible for body movement?
Correct answer
c
Rationale
The correct answer is C: Skeletal muscle. Skeletal muscles are characterized by voluntary control, meaning they are under conscious control, allowing us to move our body parts as desired. These muscles are attached to bones and are responsible for movements such as walking, running, and lifting objects. Cardiac muscle (A) is found in the heart and is involuntary, while smooth muscle (B) is found in internal organs and is also involuntary. Connective tissue (D) provides support and structure to the body but is not responsible for body movements.
a) Cardiac muscle: Cardiac muscle is involuntary and is found in the heart. It contracts rhythmically to pump blood throughout the body.
b) Smooth muscle: Smooth muscle is also involuntary and is found in various internal organs, such as the digestive tract and blood vessels. It is responsible for activities like peristalsis and regulating blood flow.
d) Connective tissue: Connective tissue is a broad category that includes structures like tendons and ligaments but does not have the contractile properties of muscle tissue. It provides support and connects various parts of the body.
