Both cardiac and skeletal muscles have striations.
There are two types of striated muscles:
- Cardiac muscle (heart muscle )
Muscle fibers and connective tissue layers make up the skeletal muscle. A skeletal muscle fibre is around 20-100 µm thick and up to 20 cm long. Like skeletal muscle, cardiac muscle is striated, but unlike skeletal muscle, cardiac muscle cannot be consciously controlled and is called involuntary muscle.
- Skeletal muscle ( muscle attached to the skeleton)
Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. Actin is a globular contractile protein that interacts with myosin for muscle contraction. Skeletal muscle also has multiple nuclei present in a single cell.
