Comparative Anatomy Lab One Abstract: This research research 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 unitedly 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 together by having a notochord, a hollow dorsal judicature instrument pile, pharyngeal slits, an endostyle, and a muscular tail extending prehistorical the anus. Species: yellowfin tuna tuna Materials: Lab manual give-and-take: The phylum Chordata is broken down into three subphyla: Vertebrata,Urochordata and Cephalochordata. tunicate larvae cave in a notochord and a nerve cord provided they are incapacitated in adulthood.
Cephalochordates have a notochord and a nerve cord but no vertebrae. In vertebrates, the notochord has been replaced by a scrawny vertebrae. The chordates and two sister phyla, the hemichordates and the echinoderms, make up the deuterostomes, a superphylum. The existent 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, send it on our website:
