There are three types of muscle tissue:
* Skeletal muscle: This is the type of muscle that is attached to bones and allows for voluntary movement. It is striated (has a striped appearance) and has multiple nuclei per cell.
* Smooth muscle: This type of muscle is found in the walls of internal organs like the stomach, intestines, and blood vessels. It is involuntary, meaning you can't consciously control it, and it is not striated.
* Cardiac muscle: This type of muscle is found only in the heart. It is striated like skeletal muscle but is involuntary like smooth muscle.
All three types of muscle tissue work by using proteins called actin and myosin to slide past each other, causing the muscle fibers to shorten and contract.
