Comparative Anatomy Lab One Abstract: This research science laboratoryoratory is to understand the classification and affinity of chordates. Introduction: In this lab manual it shows the structure of phylum Chordata, subphylum Vertebrata. The objective is to observe the major organic structure schemes and track its course of evolution from the start of the system to its front in animals alive today. Also it is to discuss how these systems toy in concert to produce life. The main topic to focus in this lab is the Chordates, which are group of animals that includes the vertebrates under the phylum Chordata. They are get in concert by having a notochord, a hollow dorsal daring instrument corduroy, pharyngeal slits, an endostyle, and a muscular tail extending erstwhile(prenominal) the anus. Species: yellowfin tuna tuna Materials: Lab manual news: The phylum Chordata is broken down into three subphyla: Vertebrata,Urochordata and Cephalochordata. tunicate larvae live a notochord and a nerve cord provided they are mixed-up in adulthood.
Cephalochordates have a notochord and a nerve cord but no vertebrae. In vertebrates, the notochord has been replaced by a drawn vertebrae. The chordates and two sister phyla, the hemichordates and the echinoderms, make up the deuterostomes, a superphylum. The existing groups of chordates and the major metozoan groups are shown in the phyletic tree in the lab manual. If you want to get a full essay, evidence it on our website:
