1. Appearance: Striated muscles have a striped or striated appearance due to the arrangement of actin and myosin filaments in a regular pattern, while non-striated muscles do not have this striped appearance.
2. Control: Striated muscles are under voluntary control, meaning they can be consciously controlled by the individual, while non-striated muscles are under involuntary control, meaning they are controlled automatically by the nervous system.
3. Location: Striated muscles are typically found in skeletal muscles, which are attached to bones and responsible for movement, while non-striated muscles are found in smooth muscles, which are found in internal organs and blood vessels.
4. Function: Striated muscles are responsible for voluntary movements such as walking, running, and lifting weights, while non-striated muscles are responsible for involuntary movements such as peristalsis in the digestive system and regulation of blood flow in blood vessels.
5. Fatigue: Striated muscles are more prone to fatigue due to their fast-twitch muscle fibers, while non-striated muscles are more resistant to fatigue due to their slow-twitch muscle fibers.
6. Structure: Striated muscles have a highly organized structure with distinct sarcomeres, while non-striated muscles have a less organized structure with no distinct sarcomeres.

Characteristic | Striated Muscle | Non-Striated Muscle ---|---|--- Appearance | Striated, banded appearance | Smooth, no striations Location | Primarily skeletal muscles attached to bones | Walls of internal organs (e.g., stomach, intestines, blood vessels) Control | Voluntary (conscious) | Involuntary (automatic) Contraction rate | Fast | Slow Strength | Higher | Lower Fatigue resistance | Less fatigue-resistant | More fatigue-resistant Organization | Myofibrils with repeating sarcomeres | Less ordered structure Myosin filaments | Thick and thin filaments form repeating sarcomeres | Thin filaments only Cell shape | Long, cylindrical multinucleated fibers | Spindle-shaped, single-nucleated cells Control of contraction | Tropomyosin and troponin regulate calcium ion binding | Calcium-dependent phosphorylation of myosin light chains Action potential | Propagated throughout the fiber | No action potentials; graded potentials Membrane system | Sarcolemma, transverse tubules, sarcoplasmic reticulum | Plasmalemma, no transverse tubules or sarcoplasmic reticulum Innervation | Innervated by multiple motor neurons | Innervated by a single axon Examples | Skeletal muscles (e.g., biceps, quadriceps) | Smooth muscles (e.g., sphincters, blood vessel walls)
