- Muscle tissue is one of the four basic tissues.
- It contains contractile proteins actin and myosin.
- Skeletal muscle is attached to bones, is under voluntary control, has long multinucleate cells (myofibers), and appears striated.
- Cardiac muscle is found only in the heart, is self activating,has single nucleate cells that are electrically connected via special junctions. It appears striated.
- Smooth muscle is in the vessels and viscera. It's non-striated, involuntary, single nucleate, and may have special junctions between the cells.
