This muscular system word search has forty words from a life science unit: the biceps and triceps, deltoid, quadriceps and hamstring, the Achilles tendon, cardiac and smooth muscle, and the actin and myosin that make a muscle contract.

The body has three kinds of muscle. Skeletal muscle, the kind you move on purpose, is striated, meaning striped under a microscope, and it is attached to bones by tendons. Smooth muscle lines the stomach, the intestines and the blood vessels and works without your thinking about it. Cardiac muscle, found only in the heart, is striped like skeletal muscle but involuntary like smooth muscle.

A muscle can only pull, never push, so skeletal muscles work in pairs. The biceps contracts to bend the elbow and the triceps contracts to straighten it, each relaxing while the other works. Inside each fiber, thin strands of actin slide past thicker strands of myosin, and the fiber shortens. The gluteus maximus is the largest muscle in the body, the sartorius down the front of the thigh is the longest, and the stapedius in the middle ear is the smallest.
