gastric region
See: carapace region f [Martin, 2005].
Large median area, in crab carapace, bounded behind by cervical suture, laterally by hepatic regions, and anteriorly by frontoorbital regions. Divisible into following subregions or lobes: epigastric, protogastric, mesogastric, metagastric, and urogastric [Williams, 1984].
Median region of dorsal carapace between frontal region and cardiac region; divided from anterior in midline into mesogastric, metagastric and urogastric regions, and with protogastric and epigastric regions laterally [Poore, 2004].
Principal dorsolateral or mesial area on carapace lying anterior to cervical groove, bounded posteriorly by cardiac region, laterally by branchial and hepatic regions, and anteriorly by frontal and orbital regions [Butler, T.H.].
Principal median area of the carapace bounded anteriorly by the frontal and orbital regions, and posteriorly by the cardiac region, and laterally by the branchial and hepatic regions [Perez Farfante and Kensley, 1997].
The principalmesial area on the carapace lying anterior to the cervical groove and bounded posteriorly by the cardiac region, laterally by the branchial and hepatic regions, and anteriorly by the frontal and orbital regions; in the true crabs, it comprises the unpaired mesogastric and metagastric regions, the urogastric lobe, the paired protogastric regions, and the epigastric lobes [Chace and Hobbs, 1969].
(Order Decapoda):
See: carapace regions f [McLaughlin, 1980].
(Order Decapoda):
Relatively large, unpaired region of carapace overlying stomach. May be variously subdivided (from anterior to posterior) into paired epigastric and protogastric as well as unpaired mesogastric, metagastric, and urogastric regions or areas. Adjoined anteriorly by frontal region, posteriorly by cardiac region [Stachowitsch, 1992].
