Verified step by step guidance

Understand the types of muscle tissue: There are three main types of muscle tissue in the human body—skeletal muscle, smooth muscle, and cardiac muscle. Each has distinct characteristics and functions.

Define voluntary movement: Voluntary movement refers to actions that are consciously controlled by the brain, such as walking, running, or lifting objects. These movements are typically under the control of the somatic nervous system.

Analyze skeletal muscle: Skeletal muscle is attached to bones via tendons and is responsible for voluntary movements. It is striated (striped appearance under a microscope) and controlled consciously.

Compare smooth and cardiac muscle: Smooth muscle is found in the walls of internal organs (e.g., stomach, intestines) and is responsible for involuntary movements like digestion. Cardiac muscle is found in the heart and is also involuntary, responsible for pumping blood.

Conclude the correct answer: Based on the definition of voluntary movement and the characteristics of skeletal muscle, skeletal muscle is the type of muscle tissue primarily responsible for voluntary movement of the body.
