While humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side. The nerve cord of an earthworm relays impulses from receptors in the worm's anterior to posterior parts of its body.
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.
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.
Essentially the same as that in any other vertebrate - including us. It is the central column of the skeleton, and the conduit for the nerve-bundle that is the spinal cord.
Neurotoxic refers to substances or agents that are harmful or destructive to nerve tissue or cells in the nervous system, including the brain and spinal cord. Exposing the nervous system to neurotoxic compounds can result in a range of negative effects, such as impaired nerve function, neurodegeneration, and neurological symptoms.
In reptiles, the nerve cord is part of the central nervous system that runs along the length of the animal's body. It consists of a chain of nerve cells that extends from the brain and helps in transmitting nerve impulses to control various bodily functions like movement and coordination.
it helps them move
yes!

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
Yes
Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.
The longitudinal bundles of nerve fibers within the spinal cord that comprise major nerve pathways are called tracts. These tracts are organized based on their function and transmit information to and from different regions of the body to the brain.
A dorsal, hollow nerve cord.
The nerve cord in an earthworm performs the same task as the nervous system of any animal. The function of the nervous system is to bring sensory information to the brain, where it is processed. Then, the brain sends signals to the body via the nervous system and those signals cause the animal to move.
