Vertebrata – Class 11 | Chapter – 4 | Short Notes Series PDF

Vertebrata: Vertebrates are species that have a backbone or vertebrae. Reptiles, humans, birds, fish, mammals, and amphibians are examples of vertebrate animals. Craniata is another name for these. Vertebrates are animal species that belong to the Subphylum Vertebrata, which means chordates with a backbone. Animalia is the vertebrate kingdom, which includes the subphylum Deuterostomia and the phylum Chordata. Olfactories is its clade, or monophyletic group, with Agnatha and Gnathostomata as infraphylums.

Characteristics of Vertebrata

• Jaws can be found in some vertebrates. Jawless species are classified as vertebrates.
• The notochord eventually becomes a vertebral column, with the vertebrae on the dorsal side.
• The anatomy of vertebrates is strikingly similar, with a vertebral column, gastrointestinal tract, and spinal cord all present.
• The internal skeleton helps to distribute muscle attachment nodes.
• The presence of the central nervous system is an important indicator. The anterior nerve tube of the spinal cord expands into the brain.
