DAVID M. NUNAMAKER. The term osteomyelitis by definition implies inflammation of the bone and its marrow contents regardless of the cause. The purpose of this chapter is to describe osteomyelitis caused by known infectious agents. The two major classifications are bacterial osteomyelitis and fungal osteomyelitis. The study of bacterial osteomyelitis includes two distinct clinical forms of the disease.
Then you are a vertebrate, too! Vertebrates make up most of the animals that we are familiar with. Exceptions to this would be things like an insect, an octopus, a lobster or crab, a jellyfish, or a clam. Most everything else is a vertebrate, with a backbone and other bones. The five classes of vertebrates are listed below.
Vertebrates are members of the larger phylum Chordata, and show all of the major chordate features at some point in their life cycles: notochord, dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.his arch is not present in other vertebrates, which may have lateral spines on the centrum instead of ventral spines. The jawless fish of today, the hagfish and lampreys, lack vertebral centra -- thus they are not vertebrates in the usual sense -- but they have neural arches on their notochords.
