What is the main difference between skeletal and smooth muscles?
| Skeletal Muscles | Smooth Muscles |

| Skeletal muscles are attached to the bones. | Smooth muscles line up the visceral organs viz. Intestines,blood vessels,pupils etc (therefore also known as visceral muscles.) |
| Skeletal muscles perform voluntary actions. | Smooth muscles are responsible for involuntary reflexes and actions. |
How does cardiac muscle differ from skeletal muscle quizlet?
Terms in this set (17) In what way does cardiac muscle differ from skeletal muscle? Cardiac muscle relies heavily on aerobic respiration, whereas skeletal muscle can function for a time in anaerobic conditions.
What are two key differences between cardiac muscle and skeletal muscle?
Key Points Cardiac muscle is involuntary and found only in the heart. Skeletal muscle is striated in regular, parallel bundles of sarcomeres. Cardiac muscle is striated, but the bundles are connected at branching, irregular angles called intercalated discs. Skeletal muscle tissue is about 15% denser than fat tissue.
How does cardiac muscle differ from skeletal muscle visible body?
How does cardiac muscle differ from skeletal muscle? Its fibers are shorter. Skeletal muscle responds to voluntary commands, whereas smooth muscle contracts involuntarily.
What do skeletal cardiac and smooth muscle have in common?
What do smooth, cardiac, and skeletal muscle all have in common? They are all uninucleated. They are all striated. The cells of these muscles are all called muscle fibers.
What is the unique features of cardiac muscle?
Unique to the cardiac muscle are a branching morphology and the presence of intercalated discs found between muscle fibers. The intercalated discs stain darkly and are oriented at right angles to the muscle fibers. They are often seen as zigzagging bands cutting across the muscle fibers.
What is the function of muscles of stomach?
The abdominal muscles support the trunk, allow movement and hold organs in place by regulating internal abdominal pressure. The deep abdominal muscles, together with muscles in the back, make up your ‘core’ muscles and help keep your body stable and balanced, and protects your spine.
