The writers of Digestive System Of Amphioxus Diagram have made all reasonable attempts to offer latest and 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). In this article we will discuss about the external morphology of branchiostoma with the help of suitable diagrams. Shape, Size and Colour: Branchiostoma is about 3.5 to 6.0 cm in length.
