These cirri are ciliated and also bear sensory papillae. The margin of oral hood and cirri are supported by stiff gelatinous skeletal rods. 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. Note: This diagram leaves out two very important structures: the frontal eye and the lamellar organ.
Lamprey Nervous System Amphioxus Nervous System Dictionary First, a word of warning. Neuroanatomy is extremely difficult. 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. The amphioxus (lancelet) was first described by Pallas in 1774 and incorrectly assigned to mollusks. Since then, amphioxus attracted generations of zoologists.
2021-01-18 · Extended Data Fig. 10 MBD4/MECP2 isoform expression in the european amphioxus. Diagram representing the sequences used to uniquely map RNA-seq reads to each isoform across different tissues and The current paper on the amphioxus genome confirms that, and in particular reveals an interesting fact: while the ascidian genome has undergone some major remodeling that makes it very different from our own, the amphioxus genome seems to have conserved many ancestral features and may very well be a good proxy for examining the genetics of the last common chordate ancestor.

Its body axis is formed by a well-developed notochord, extending from the very tip of the rostrum (Fig. 9.2) to the end of the tail. The amphioxus CNS lacks ventral roots; the paraxial muscles send muscle tails to synapse directly with motor neurons at the periphery of the CNS (Flood 1968).
