The ventral nerve cord, as its name suggests, is a cord of nervous tissue that runs the length of the animal in the lower part of its body. Grasshoppers are segmented animals, and each segment is controlled by its own ganglion. A ganglion is a package of neurons, containing anything from a few dozen to hundreds of thousands of neurons. The ganglia of each segment are joined to their neighbours by the interganglionic connectives(although some ganglia are fused directly together). Thus the ventral nerve cord consists of this chain of linked ganglia. http://www.st-andrews.ac.uk/~wjh/jumping/motorsys.htm
if it gets attacked by a predator they will go for the top and it will still be able to move

What organisms have a ventral nerve cord?
A ventral nerve cord can be found in on the bottom (or lay on the bottom) of the organisms, such as grasshoppers and earthworms. Hope this helps! - AJ
What does the ventral nerve cord do in a earthworm?
there is not a ventral nerve cord
How does the human axial nerve cord differ from that of the grasshopper?
Humans have a spinal cord down the dorsal surface of their back. Grasshoppers have a nerve ladder down the ventral surface of their belly.
Are the ventral nerve cord and the ventral blood vessel connected?
no
Are the ventral nerve cord and ventral blood vessel connected?
no
What is the function of the ventral nerve cord in an earthworm?
The ventral nerve cord makes up nearly all of the nervous system in the earthworm. It goes from the anterior (front) end to the posterior (back) end. It's function is simple; it's the nerves in the worm! If dissected, the nerve cord looks like a thin white line on the ventral (belly) side on the inside of the skin.
What is the function of a ventral nerve cord in crayfish?
It helps the crayfish to move around in the water. It is located in a spot that makes it difficult for predators to get at.
Does the brain attach to the ventral nerve cord of a worm?
yes!
How does the position of the worms nerve cord compare with your nerve cord?
The position of the worms nerve cord compare with your nerve cord is it placement along the ventral surface of the body. Our spinal cord is protected by vertebra were the worms is unprotected.
A vertebrates backbone is part of what internal skeleton?
Ventral nerve cord, vertebra, dorsal nerve cord, and notocord.
How does the position of a worms nerve cord compare with your nerve cord?
an earthworm's nerve cord is directly opposite that of a human's. the earthworm's nerve cord is along the ventral side (underside) of its body and the human's nerve cord is on the dorsal side (upperside) of the body along all of the internal organs
What organs in an earthworm make up the nervous system?
ventral nerve cord
