∙ 14y agoYep, they do. They are merely extremely thin and small, such that, if you did not know what you were looking for, you could be staring right at it and not know what it was. (Said by my zoology teacher.)

∙ 15y agoYes. all animals that have a an endoskeleton and a backbone will be present with a dorsal nerve cord.
Wiki User
∙ 12y agoWell, based on the fact of vertebrates... I think that humans have a possibility of having a Dorsal Nerve Cord... You may research with other sites if I am not correct. Sorry!

What organisms have pharyngeal gill slits and a dorsal hollow nerve cord at some time in their development?
Chordates
The three things all chordates have?
Chordates all possess a notochord (dorsal supporting rod), gill slits, and a dorsal nerve cord some time in their life cycles.
At some point in their lives all chordates have what characteristics?
All chordates have a notochord at some stage in their development, even if it is only at the embryonic stage. The notochord is a flexible structure located in front of the dorsal nerve, which all chordates also have.
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 is a hollow nerve cord?
The dorsal nerve cord is one of the embryonic features unique to chordates, along with a notochord, a post-anal tail and pharyngeal slits. It is a hollow cord dorsal to the notochord. It is formed from a part of the ectoderm that rolls, forming the hollow tube, compared to other animal phyla, which have solid, ventral tubes. The dorsal nerve cord is later modified into the brain and spinal cord. Dorsal nerve cord is mainly found in phylum Vertebrata. Dorsal means the "back" side, as opposed to the belly side (ventral).
