The vertebrates have an internal skeleton and vertebral column, allowing a different muscle distribution that can be used for movement. The phylum vertebrates have notochord in the embryonic period. In adults, the notochord is replaced by a bony vertebral or cartilaginous column, Vertebrates apart from the chordate characters have kidneys, a heart with either two, three, or four chambers, and paired appendages that may be limbs or fins.
What are the Basic Features of Phylum Vertebrate?
The phylum vertebrate includes all craniates that range from mammals to agnathans. The vertebrates’ body for a living is built on the fundamental plan along with modifications for living in various conditions. The basic features are discussed in our Phylum Vertebrata homework writing help as follows:
Vertebral Column: The vertebrates have a vertebral column that forms the protecting and supporting axis of a body. The vertebral column offers muscle attachment regarding locomotion and provides rigidity to the soft body. In the aquatic forms thermoregulation, integumentary, and reception to the external stimuli are done by the internal skeleton, mainly the vertebral column.
Development: During the development phase, the mesodermal cells around the notochordal sheath form the skeletogenous layer. Some of the mesodermal cells migrate to the notochordal sheath. This wat the notochord is surrounded by mesodermal cells.
The Divisions of Phylum Vertebrata
There are three divisions of Phylum Vertebrate that are included in our Phylum Vertebrata assignment help in AUS:
The initial two phyla have little species. The major phylum is vertebrate, wherein you can find many reptiles, fishes, animals, and birds. The vertebrates have a backbone, which is made up of cartilage or bone. There is a nervous system, a circulatory system, a brain enclosed in a skull, and a skeletal system offering proper support and shape.
The Phylum Vertebrata has five classes and they are the following:
