amphioxus is therefore the most appropriate outgroup for understanding the origins of vertebrate genome content and structure, and how duplicated genes in vertebrates have evolved new functions.

- "The chordate amphioxus: an emerging model organism for developmental biology" Branchiostoma lanceolatum, the European lancelet or Mediterranean amphioxus, is a lancelet in the subphylum Cephalochordata. It is a marine invertebrate with a notochord but no backbone and is used as a model organism to study the evolutionary development of vertebrates.

The various parts of the brain are all jammed together, and it takes time before you begin to be comfortable with how they're all related to each other. So, if you're just starting, relax.

I. Morphology of the major vessels of the pharyngeal area The pattern of circulation in amphioxus is forward ventrally and backwards dorsally. In addition, circulating corpuscles, usually associated with the blood of higher chordates, are absent. The circulatory system of amphioxus consists of well defined contractile vessels and vascular spaces or sinuses within a connective tissue matrix. Amphioxus lanceolatusand for the first time described their notochord (see Glossary, Box 1), the defining morphological trait of chordates (Yarrell, 1836). After these initial studies, and until the beginning of the 20th century, amphioxus was considered to be a vertebrate.

The gastrula here resembles the one in his 1905 diagram, although the angle between the A/V axis and A/P axis is somewhat less, (11) Recently, these authors oriented the A/V axis perpendicular to the A/P axis, possibly from reading Hatschek inattentively; otherwise there is no precedent for such an arrangement in any of the primary or secondary literature on amphioxus embryology, and (12) From Although amphioxus resembles a fish, it has a much simpler organisation (Fig. 9.1). There is no true head, and paired special sense organs are entirely lacking. Its body axis is formed by a well-developed notochord, extending from the very tip of the rostrum (Fig.

ADVERTISEMENTS: In Branchiostoma, nervous system is simple, having no brain as found in higher chordates. Nerve Cord: There is a mid-dorsal, hollow, tubular neural tube or nerve cord lying above the notochord.
