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). However, the amphioxus CNS does have dorsal roots, which probably receive sensory input and are serially arranged like the dorsal roots of vertebrates (Wicht and Lacalli 2005). 2015-04-17 · Amphioxus, placed in the Cephalochordata subphyllum, is a marine animal in the Chordata group. Chordata includes, in addition to this group, Urochordata (among which there is Pyrosomida), hagfishes and vertebrates (fishes, amphibians, reptiles, birds and mammals). The circulatory system of amphioxus consists of well defined contractile vessels and vascular spaces or sinuses within a connective tissue matrix. The contractile vessels have a discontinuous endothelial lining resting on a basal lamina and are enclosed by a simple layer of contractile myoepithelial cells.
