circumesophageal connective
(Order Decapoda):
One of two strands of nerve tissue surrounding esophagus and connecting dorsal supraesophageal ganglia with posterior subesophageal ganglia. May bear ganglia (paraesophageal ganglia). (Syn. esophageal connective) [Stachowitsch, 1992].
(Subclass Branchiura):
One of two short, relatively thick strands of nerve tissue surrounding esophagus and connecting dorsal supraesophageal ganglion with subesophageal ganglion. Innervates antennae. (Syn. paraesophageal connective) [Stachowitsch, 1992].
(Subclass Copepoda):
One of two strands of nerve tissue surrounding esophagus and connecting supraesophageal ganglion to ventral nerve cord. (Syn. esophageal connective) [Stachowitsch, 1992].
(Class Ostracoda):
One of two strands of nerve tissue surrounding esophagus and forming lateral part of circumesophageal nerve ring. Joins supraesophageal ganglion and complex formed by subesophageal ganglion and more or less concentrated ventral nerve cord [Stachowitsch, 1992].
(Class Remipedia):
One of two strands of nerve tissue surrounding foregut and joining dorsal brain to ventral nerve cords [Stachowitsch, 1992].
