They move back and forth to either speed the roach up or slow it down. The very long metathoracic legs are the roach's back legs, and they move the roach forward. Using its metathoracic legs, a roach can move about 50 body lengths in a second. A human moving that quickly would be running about 200 miles per hour.
Most cockroaches have three joints on each leg, which means they have 18 knees! The skeleton is made of a hard substance called chitin. When a skeleton is on the outside, it is called an exoskeleton. The exoskeleton supports and protects the roach's insides.
