Definitions
Supraesophageal ganglion
- (Taxon-specific: Order Amphipoda) Concentration of nerve tissue above (anterior to) esophagus in head. Connected to subesophageal ganglion by pair of esophageal connectives.
(syn. brain) [Stachowitsch, 1992] - (Taxon-specific: Order Isopoda) Concentration of nerve tissue above (anterior to) foregut. Connected to subesophageal ganglion by pair of esophageal connectives.
(syn. brain) [Stachowitsch, 1992] - (Taxon-specific: Subclass Branchiura) Concentration of nerve tissue anterior (dorsal) to esophagus. A proto-, deutro- and tritocerebrum may be distinguished. Connected to subesophageal ganglion by pair of circumesophageal connectives. Innervates antennules and eyes. [Stachowitsch, 1992]
- (Taxon-specific: Class Ostracoda) Concentration of nerve tissue anterior (dorsal) to esophagus. Connected to ventral nerve cord by pair of circumesophageal connectives.
(syn. brain) [Stachowitsch, 1992] - (Taxon-specific: Class Ostracoda) Concentration of nerve tissue anterior to esophagus and innervating, among others, compound eyes. Fused with circumesophageal connective to form circumesophageal nerve ring.
(syn. brain) [Stachowitsch, 1992] - (Taxon-specific: Order Euphausiacea) Concentration of nerve tissue in anterior region of cephalothorax; located above (anterior to) esophagus and somewhat anteroventral to stomach. Joined to chain of postoral ganglia by pair of esophageal connectives.
(syn. brain) [Stachowitsch, 1992]
