The nerve cord of an earthworm is ventral because the nerve cord runs down the ventral, or belly, plane of the organism compared to a dorsal nerve cord, which would run down the dorsal, or back, plane of the organism.

∙ 14y agoLike humans, A dorsal nerve cord would be present on the "back" of the person or chordate.
Some invertebrates such as arthropods, have a ventral nerve cord on the "belly."
This type of cord is usually made up of connected branches or a rope style chain instead of 1 solid cord that runs the length of the body. Therefore, the body would have a better range of movement, because of the ability to have several body sections. This would mean that there is better speed with more appendages per section, if 1 section is damaged it doesn't mean the whole is damaged, and more flexibility.

∙ 10y agoThe ventral nerve cord in the earth worm acts just like your spinal nerves.
It produces movement for each segment of the earthworm. It also picks up sensory information coming in from the outside.

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.
What does the ventral nerve cord do in a earthworm?
there is not a ventral nerve cord
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
Are the ventral nerve cord and the ventral blood vessel connected?
no
Are the ventral nerve cord and ventral blood vessel connected?
no
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
Does the brain attach to the ventral nerve cord of a worm?
yes!
A vertebrates backbone is part of what internal skeleton?
Ventral nerve cord, vertebra, dorsal nerve cord, and notocord.
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 organs in an earthworm make up the nervous system?
ventral nerve cord
Where do the small nerves go when they branch from a ganglion of the ventral nerve cord on an earthworm?
The ventral nerve cord runs throughout an earthworm's body. When they start to branch from ganglion the nerve cords are still present throughout the segments.
What is a planarian ventral nerve cords?
Planarians are bilaterally symmetric worms that possess almost unlimited regenerative capacities. The ventral nerve cords are located in the segment (brains) of the worm.
