Are the setae on an earthworm segment paired?
Yes on lateral and ventral surfaces.
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 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.
How does sperm from one earthworm enter another earthworm for cross-fertilization?
Two worms come together along their ventral sides and become temporarily joined by the secretion of a "slime tube". Sperm is discharged from the seminal vesicles of both Worms's long seminal grooves on the ventral body surfaces, and enter the seminal receptacles of the other worms.
Ventral view is front side?
ventral is from the base view. so imagine a dog standing up. Dorsal would be looking down onto its back and ventral would be lokking up towards its tummy from the ground.
Is the dorsal side of an earthworm lighter than the ventral side?
The ventral side is lighter than the dorsal.
Is the dorsal side of an earthworm lighter than the ventral?
The ventral side is lighter than the dorsal.
What is different about the ventral side of an earthworm?
The dorsal side of an earthworm is darker than the ventral side because of the dorsal blood vessal that runs along the top of the digestive track and just under the skin. There is a ventral blood vessal, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
What is ventral and dorsal?
Ventral is the lower part of the body(light-colored on a earthworm)(stomachs on a human) and dorsal is the top(butts on a human)(darker side on a earthworm)
Why is the earthworm dissected dorsal side up?
Earthworm is an invertebrate hence it has its nerve chord at the "front" of its body, that is at the ventral surface.To avoid causing damage to the nerve chord,earthworm(invertebrate)is dissected dorsal side up.
What does the ventral nerve cord do in a earthworm?
there is not a ventral nerve cord
Are the setae on an earthworm segment paired?
Yes on lateral and ventral surfaces.
Which side is darker on woodlice the dorsal or ventral surface?
The dorsal side of an earthworm is darker than the ventral side. This is because of the dorsal blood vessal that runs along the top of the digestive track and just under the skin. There is a ventral blood vessel, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
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.
Does the earthworms ventral nerve cord traverse the entire length of the body?
No, they only have a ventral blood vessel.
What do the ventral blood vessels do in earthworm?
the transport blood throughout the worm
Is the dorsal blood vessel different from the ventral blood vessel in an earthworm?
yes.
