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.
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.
there is not a ventral 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

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

ventral nerve cord
In cockroaches, the ventral nerve cord is part of the central nervous system, running along the underside of the body. It consists of a chain of segmented ganglia, which are clusters of nerve cells that control various bodily functions and movement. This structure is crucial for coordinating locomotion and processing sensory information. The ventral nerve cord connects to peripheral nerves that extend to different body segments.
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.
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.
