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 else can I help you with?
Does the earthworms ventral nerve cord traverse the entire length of the body?
No, they only have a ventral blood vessel.
What function in the earthworm has a similar function as the human heart?
The actual "pumping system" of a worm can be mistaken as a heart, but it has no chambers. They are actually aeortic arches that pump the blood down the ventral side of the worm and it returns on the dorsal vessel.
Where do the small nerves go when they branch from a ganglion of the ventral nerve cord on an earthworm?
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.
What is ventral-lateral?
Ventral-lateral is a medical term refering to the front (ventral) and side (lateral ) of a body structure. A broken bone in the arm can be described as showing a ventral-lateral angulation, meaning it is sticking to the front and the side.
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 an earthworm lighter than the ventral side?
The ventral side is lighter than the dorsal.
What is the ventral side of the earthworm?
The ventral side of an earthworm refers to the underside of its body. It is the side that is typically lighter in color and is in contact with the ground as the earthworm moves. You can identify the ventral side by looking for the earthworm's central nerve cord running along its length.
Is the dorsal side of an earthworm lighter than the ventral?
The ventral side is lighter than the dorsal.
Is the dorsal blood vessel different from the ventral blood vessel in an earthworm?
yes.
What is ventral and dorsal?
Ventral refers to the belly side or front of an organism, while dorsal refers to the back or upper side. These terms are commonly used to describe the positioning of structures or features on an organism.
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
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 different between the top and bottom side of an earthworm?
how can you distinguish between the top and bottom side of an earthworm
Where is the central nerve cord located in an earthworm?
The central nerve cord in an earthworm is located on the ventral side of its body, running along the underside. It is part of the earthworm's nervous system and helps in coordinating movement and responses to stimuli.
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
