Characteristics of muscles (smooth muscles, skeletal muscles and Cardiac muscles)
Differences between smooth and skeletal muscles
| Smooth muscles | Skeletal muscles | |
| 1. | Not straited | striated |
| 2. | involuntary | Voluntary |
| 3. | Not under conscious control | Under conscious control |
| 4. | Found within walls of internal organ | Attached to bones e.g. biceps |
Differences between Smooth Muscles and Cardiac Muscles
| Cardiac muscles | Smooth muscle | |
| 1. | Striated | Not striated |
| 2. | Found in heart wall | Found in internal organs |
| 3. | innervated by the autonomic nervous system via its cardiac pacemaker | are directly innervated |
| 4. | do not regenerate | Regenerate when injured |
Differences between cardiac and skeletal muscles
| Skeleton muscle | Cardiac muscle | |
| 1. | controlled by the somatic nervous system | involuntarily controlled |
| 2. | cells are cylindrical in shape | are semi-spindle in shape |
| 3. | are attached to the bone | is found in the heart |
| 4. | skeletal muscle cells are multi-nucleated. | only one or two nuclei in the cardiac muscle cells |
| 5 | Has no gap junction | Has gap junction |
| 6 | Few mitochondria | Many mitochondria |
