yes!
there is not a ventral nerve cord
An earthworm has a paired brain attach to it nerve cord, that flows to its ganglia. The Clitellum ( the ring or band on the worm) is were the worm senses things. An earthworm can also not feel pain.
no
no
It't the Ganglia (brain)
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
The Nervous Organs in an Earthworm include: * The brain * The ventral nerve cord I hope this informaton is helpful to you!! =)
The dorsal nerve cord is one of the embryonic features unique to chordates, along with a notochord, a post-anal tail and pharyngeal slits. It is a hollow cord dorsal to the notochord. It is formed from a part of the ectoderm that rolls, forming the hollow tube, compared to other animal phyla, which have solid, ventral tubes. The dorsal nerve cord is later modified into the brain and spinal cord. Dorsal nerve cord is mainly found in phylum Vertebrata. Dorsal means the "back" side, as opposed to the belly side (ventral).
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.

In a grasshopper, the ventral nerve cord encircles the digestive tract at the anterior end, where it connects to the brain. This connection occurs in the head region, specifically around the esophagus, forming a structure known as the subesophageal ganglion. This arrangement allows for coordinated control of the nervous system and digestive functions.
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.
