Muscle tissue

• Muscles are made from elongated cells that form fibres.
• Protein filaments in muscle cells include actin and myosin.
• Actin and myosin contract to allow movement to occur.
• Skeletal muscle is attached to the bone. Contraction and relation is controlled using these muscles.
• Cardiac muscle will only be found in the heart, contracting at a steady rate making the heart beat. This muscle cannot be voluntarily controlled.
• Smooth muscle will be found in the walls of hollow organs, this muscle cannot be controlled.
