Grasshopper Jumping



A grasshopper has antagonistic muscles called the flexor and extensor muscles which ( are attached to the interior of the exoskeleton)

The rear legs are bigger and longer and (are adapted for jumping).

Flexor muscle contract to flex the leg / prepare for jumping.

Flexor muscle relaxed, extensor muscle contracts.

Causes the rear legs to extend and pushes against the ground 

The thrust created propels the grasshopper forwards and upwards.
