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
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.
lol, are you doing sections 1 and 2 for mollusks and segmented worms?
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.
there is not a ventral nerve cord
lol, are you doing sections 1 and 2 for mollusks and segmented worms?
Yes
Yes, chordate's nerve cord is hollow as opposed to animals that are non chordate with a nerve cord which are solid.
A dorsal, hollow nerve cord.
Annelid worms have a hydrostatic skeleton that helps them move and maintain their body shape. They also regulate their body functions through nerve ganglia located along their ventral nerve cord, which control activities like movement, feeding, and reproduction. Additionally, annelids have specialized structures like setae that aid in locomotion and burrowing.
starting in the spinal cord, trace a motor pathway to the adductor muscles of the thigh. Include the spinal cord root, spinal nerve, nerve plexus, and specific peripheral nerve involved in the pathway
yes it does
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
