A type of muscle tissue that found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder and uterus, is under control of the autonomic nervous system. A. Cardiac Muscle B. Skeletal Muscle C. Smooth Muscle D. Biceps Muscle

The correct answer is **C. Smooth Muscle**.<br /><br />Here's why:<br /><br />* **Smooth Muscle:** This type of muscle is found in the walls of internal organs like those listed (blood vessels, GI tract, bladder, uterus). It's involuntary, meaning we don't consciously control it, and it's regulated by the autonomic nervous system.<br /><br />* **Cardiac Muscle:** Found only in the heart. While also involuntary and controlled by the autonomic nervous system, it has a distinct structure and function different from smooth muscle.<br /><br />* **Skeletal Muscle:** This is the type of muscle attached to bones and responsible for voluntary movement. We consciously control skeletal muscles.<br /><br />* **Biceps Muscle:** This is a specific skeletal muscle located in the upper arm. It's not a general type of muscle tissue.<br />
