Locomotion Of Grasshopper 955a

Grasshoppers have 3 pairs of legs

• It is long and muscular. • Has antagonistic muscles. • The flexor and extensor muscles are attached to the interior surface of the exoskeleton. • Flexors are muscles that bend a t while extensors straightens it.

To walk, a grasshopper uses 2 legs to its body off the ground while the other 2 legs move together to make successive steps. Here’s a example of how grasshopper walks :-D IT DOES NOT USE ITS REAR LEGS!

Extensor muscle and flexor muscle are used to in the mechanism of hopping.

• • • •

Flexor Muscle = Contract Extensor Muscle = Relax Legs Fully Flexed. Legs Forms A “Z” Shape.

• • • •

Flexor Muscle = Relax Extensor Muscle = Contract Hind legs extends backwards. For propelling in the air.

The magnitude of the force.. Low Force = Short distance.

High Force = Far distance.

Time to build the force. If the thrust builds up too slowly, the legs will extend before the thrust reaches its maximum. Once the grasshopper is standing on tip-toe, it can't thrust against the ground any more.

• Try this: flex your arm so that your hand is close to your shoulder • While arm is flexed, place palm of hand on a wall • Push the wall with your hand, extending your arm • Feel the push backwards? That show a grasshopper jumps.
