Anterior ganglion of the ventral nerve cord, located beneath (posterior to) the esophagus and connected dorsally to the tritocerebrum. (Syn. subenteric ganglion) [Brusca and Brusca, 2002].
Nerve plexus below esophagus in head of malacostracans [Moore and McCormick, 1969].
Nerve plexus below esophagus [McLaughlin, 1980].
(Order Diplostraca):
Brain [Stachowitsch, 1992].
(Class Cephalocarida):
Concentration of nerve tissue below (posterior to) esophagus. Connected to brain by connectives surrounding esophagus. (See also ventral nerve cord) [Stachowitsch, 1992].
(Order Tanaidacea):
Main concentration of nerve tissue above (anterior to) esophagus. Connected to subesophageal mass by esophageal connectives [Stachowitsch, 1992].
(Order Decapoda):
Concentration of nerve tissue below (posterior to) esophagus. Consists of fused ganglia of somites bearing mouthparts (mandibles to third maxillipeds) and is connected to supraesophageal ganglion by pair of circumesophageal connectives. Continues posteriorly as ventral nerve cord. See: postesophageal ganglion [Stachowitsch, 1992].
(Order Amphipoda):
Concentration of nerve tissue below (posterior to) esophagus. Consists of fused ganglia of mouthparts (mandibles, maxillules, maxillae, maxillipeds) and is connected to brain (supraesophageal ganglion) by pair of esophageal connectives. Continues posteriorly as ventral nerve cord [Stachowitsch, 1992].
(Order Isopoda):
Concentration of nerve tissue below (posterior to) foregut. Consists of fused ganglia of mouthparts (mandibles, maxillules, maxillae, maxillipeds). Continues posteriorly as ventral nerve cord [Stachowitsch, 1992].
(Order Mysida):
In certain mysidaceans, concentration of nerve tissue below (posterior to) esophagus. Joined to supraesophageal ganglion by pair of esophageal connectives and continues posteriorly as ventral nerve cord [Stachowitsch, 1992].
(Order Stomatopoda):
Postoral ganglion [Stachowitsch, 1992].
(Subclass Branchiura):
Concentration of nerve tissue below (posterior to) esophagus. Connected to supraesophageal ganglion by pair of circumesophageal connectives and adjoined posteriorly by partially fused thoracic ganglia. Innervates mandibles, maxillules, and maxillae [Stachowitsch, 1992].
(Subclass Cirripedia):
Concentration of nerve tissue below (posterior to) esophagus. Joined to supraesophageal ganglion by pair of esophageal connectives. Continuous posteriorly with ventral nerve cord or fused with ganglia of ventral nerve cord to form ventral nerve mass [Stachowitsch, 1992].
(Class Ostracoda):
Concentration of nerve tissue posterior to esophagus. Fused to more or less concentrated ventral nerve cord to form posterior part of circumesophageal nerve ring [Stachowitsch, 1992].
(Class Remipedia):
Brain [Stachowitsch, 1992].
