supra-esophageal ganglion
Nerve plexus above esophagus in head of malacostracans [Moore and McCormick, 1969].
Nerve plexus above esophagus, equivalent to brain [McLaughlin, 1980].
(Order Cladocera):
Main part of brain above (in front of) esophagus. Consists of protocerebrum (preantennular ganglion) and deutocerebrum (antennular ganglion) [Stachowitsch, 1992].
(Order Notostraca):
Main part of brain above (in front of) esophagus. Consists of protocerebrum (preantennular ganglion) and deuterocerebrum (anetennular ganglion). (See also tritocerebrum) [Stachowitsch, 1992].
(Order Anostraca):
Main part of brain above (in front of) esophagus. Consists of protocerebrum (preantennular ganglion) and deuterocerebrum (antennular ganglion); joined to tritocerebrum by connectives [Stachowitsch, 1992].
(Order Cumacea):
Main concentration of nerve tissue above (anterior to) esophagus. Continues posterior to esophagus as ventral nerve cord [Stachowitsch, 1992].
(Order Decapoda):
Main concentration of nerve tissue lying above esophagus at anterior end of cephalothorax; consists basically of protocerebrum, deutocerebrum, and tritocerebrum. Gives rise to numerous nerves extending to anterior appendages and is connected to subesophageal ganglion and ventral nerve cord by pair of circumesophageal connectives. (Syn. brain) [Stachowitsch, 1992].
(Order Mysida):
Main concentration of nerve tissue above (anterior to) esophagus. Connected to ventral nerve cord (in certain mysidaceans to subesophageal ganglion) via pair of esophageal connectives [Stachowitsch, 1992].
(Order Stomatopoda):
Major concentration of nerve tissue in anterior region of head (cephalon); joined to ventral ganglia (postoral ganglia) and ventral nerve cord by pair of long circumoral connectives [Stachowitsch, 1992].
(Order Leptostraca):
Main concentration of nerve tissue in head (cephalon). Connected to ventral nerve cord by pair of esophageal connectives [Stachowitsch, 1992].
(Subclass Cirripedia):
Anterior concentration of nerve tissue. Joined to subesophageal ganglion by pair of esophageal connectives. (Syn. brain, cerebral ganglion) [Stachowitsch, 1992].
(Superorder Syncarida):
In anaspidacean, main concentration of nerve tissue above (anterior to) esophagus. Connected to ventral nerve cord via pair of esophageal connectives. (Syn. brain) [Stachowitsch, 1992].
(Order Thermosbaenacea):
Brain [Stachowitsch, 1992].
