In vertebrates, the nerve cord is located within the vertebral column, which is part of the central nervous system. Specifically, it is called the spinal cord and runs along the dorsal side of the body, protected by the vertebrae. The spinal cord extends from the base of the skull to the lower back, transmitting signals between the brain and the rest of the body.
What else can I help you with?
Does a lamprey have a dorsal nerve cord?
Yes
Does a kangaroo have a dorsal nerve cord?
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
What animals have a tubular nerve cord and gill slits at some point in their lives?
No, not all vertebrates have tubular nerve cord.
A vertebrates backbone is part of what internal skeleton?
Ventral nerve cord, vertebra, dorsal nerve cord, and notocord.
What makes a chordate a vertebrate?
Chordates have a nerve cord running their backs. Some chordates are vertebrates. They have vertebrate, or a segmented backbone, protecting the nerve cord.
Cavity enclosing the nerve cord?
Dorsal hollow nerve cord in some invertebrates (like chordates) or vertebrates.
What does the vertebrates protect?
it protects a hollow nerve chord
Does birds have spinal cord?
Yes, they have a dorsal (at the back) nerve chord as they are vertebrates ( they have an internal skeleton).
The notochord of vertebrates is replaced by a nerve cord when the animal becomes an adult?
No, the notochord and the nerve cord arise from different germ layers. The notochord is replaced by an ossified backbone, though there are still remnants between the vertebrae. The nerve cord, however, is protected by the ossified vertebral column.
Where is the smallest nerve located?
The smallest nerve is called the Homologous Tracheal and it is located in the Jawed Vertebrates. (BTW I'm only 10)
What is the basis in classifying animals into two major groups?
Probably invertebrates and vertebrates (although "chordates" is better for vertebrates) since the two groups are technically distinguished by the presence of a ventral cord in the invertebrates and a dorsal nerve cord (in their back). All but a few minor groups of chordates have their dorsal nerve cord protected by vertebrae so commonly, most people say invertebrates and vertebrates (until high school and college).
What Central nervous system?
The complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
