Does the brain attach to the ventral nerve cord of a worm?
yes!
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 is the function of a nerve cord in a worm?
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.
What are the parts of earthworms nervous system?
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.
Why do worms have a ventral nerve cord?
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.
What does a nerve cord do in a worm?
it helps them move
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.
What is the function of the ventral blood vessel of a worm?
Blood vessel on the bottom of a worm Blood vessel on the bottom of a worm
The function of the earthworms blood vessels?
The earthorm has a closed circulatory system with five main blood vessels:Dorsal (above the digestive tract) - it moves blood forwardThe remaining four all move the blood to the rear of the earthworm: Ventral (beneath the digestive tract)Subneural Vessel (below the nerve cord)Right & Left Lateroneural vessels (either side of nerve cord)
Is the dorsal side of the worm is lighter than the ventral side?
Yes!
What do the ventral blood vessels do in earthworm?
the transport blood throughout the worm
Is the dorsal side of the worm lighter in color than the ventral side?
Yes!
