The major type of muscle that is NOT listed among the options provided is the "rough" muscle. Let's break down the types of muscles listed and identify which one is not a major type:
1. Smooth Muscle: This type of muscle is found in the walls of internal organs like the stomach, intestines, and blood vessels. It is responsible for involuntary movements and is under the control of the autonomic nervous system.
2. Skeletal Muscle: Skeletal muscles are attached to bones and help facilitate movement. They are under voluntary control, meaning you can consciously control their contractions to perform various movements.
3. Cardiac Muscle: Cardiac muscle is found in the heart and is responsible for pumping blood throughout the body. It is also under involuntary control, like smooth muscle.
Given these explanations, the correct answer is "rough" muscle, as it is not a major type of muscle in the human body.
