If you are referring to the spinal cord then the vertebrae, dura mater, arachnoid mater and pia mater. If referring to the actual bones then supportive muscles, intervertebral discs, connective tissue including adipose (fat).
i know but not telling
Yes. They are vertebrates and all vertebrates have a spinal cord.
The backbone surrounds and protects the spinal cord in vertebrates. It provides structural support to the body and allows for flexibility and movement while also protecting the delicate nerves of the spinal cord.
it protects a hollow nerve chord
No, not all animals have spinal cords. Only vertebrates have spinal cords. (However, their are plenty of spineless people and they are vertebrates)
Vertebrates are called so because they have a vertebral column, or backbone, made up of individual vertebrae that protect the spinal cord. This distinguishing feature sets them apart from invertebrates, which lack this type of internal support structure.
the skull and the backbone
the species having spinal cord are vertebrates
spinal cord
the CNS is your brain and spinal cord, so the skull protects the brain, and the vertebrates in your spine help protect the nerves in your spine.
That's correct. Vertebrates are a subphylum of the phylum Chordata, which also includes organisms without backbones. Vertebrates are characterized by their spinal columns, or vertebrae, which give them structural support and protect their spinal cord.
Are known as vertebrates.
