right on the 7th segment
the brain and spinal cord.
spinal cord and brian
The nervous system consists of the brain and the spinal cord. Nerve fibers of the spinal cord spread out to the different part of body. These nerve fibers are part of the peripheral nervous system and are the nerves that are found outside the spinal cord and brain.
Spinal Cord
the central nervous system which consists of the brain and spinal cord. the peripheral nervous system which consists of nerves and ganglia (collection of nerve cell bodies outside the central nervous system). AND -peripheral. -central.
there is not a ventral nerve cord
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.
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
whayt does cords main
you go to scarlett?
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.
ventral nerve cord
it drains blood from the nerve cord n' stuff :)
Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.
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.
It't the Ganglia (brain)
The five hearts and esophagus (which are on top of the central nervous cord)
