Verified step by step guidance

Understand the types of muscle tissue: There are three types of muscle tissue in the human body—skeletal, cardiac, and smooth muscle. Skeletal muscles are voluntary, while cardiac and smooth muscles are involuntary.

Identify the muscle types in the options: The muscle in the wall of the urinary bladder is smooth muscle, the muscle that extends the arm at the elbow is skeletal muscle, the muscle in the wall of the heart is cardiac muscle, and the muscle of the stomach is smooth muscle.

Recognize the characteristics of voluntary muscles: Voluntary muscles are those that can be consciously controlled. Skeletal muscles fall into this category as they are responsible for movements like extending the arm.

Determine which muscle is voluntary: Based on the characteristics of muscle types, identify that the muscle that extends the arm at the elbow is a skeletal muscle, which is voluntary.

Conclude the answer: The muscle that extends the arm at the elbow is the voluntary muscle among the options provided.
