Midgut
- See: Mesenteron [Martin, 2005]
- See mesenteron. [McLaughlin, 1980]
- (Taxon-specific: ) Elongate section of digestive tract between esophagus and hindgut. Occasionally one may distinguish between a more expanded stomach region anteriorly and a more narrow posterior intestinal region. May bear pairof digestive ceca anteriorly. (straight, coiled = convoluted). [Stachowitsch, 1992]
- Elongate section of digestive tract between esophagus and hindgut. Extends through thorax and most of abdomen and bears two ceca anteriorly. [Stachowitsch, 1992]
- Elongate, somewhat exapanded section of digestive tract between esophagus and hindgut in trunk. Bears pair of digestive ceca anteriorly. [Stachowitsch, 1992]
- (Taxon-specific: Family Pycnogonidae) Elongate section of digestive tract between esophagus and hindgut. Extends through thorax, and most of abdomen and bears pair of midgut diverticula anteriorly. [Stachowitsch, 1992]
- Greater part of digestive tract; extends posteriorly from esophagus through thorax and most of abdomen.
(syn. mesenteron) [Stachowitsch, 1992] - Relatively short section of digestive tract between stomach and hindgut. Wall of midgut distinguished from that of stomach by larger (syncytial) cell structure. [Stachowitsch, 1992]
- Elongate section of digestive tract between stomach and rectum. Digestive diverticula open into digestive tract at border of stomach and midgut. [Stachowitsch, 1992]
- Region of digestive tract between foregut and hindgut. Either restricted to posterior section of pyloric stomach or corresponding to greater part of intestine. Not lined by cuticle.
(syn. mesenteron) [Stachowitsch, 1992] - Elongate section of digestive tract between foregut (esophagus and stomach) and hindgut. Gives rise to various ceca anteriorly (at stomach/ midgut border) and posteriorly. [Stachowitsch, 1992]
- Poorly defined section of digestive tract between foregut and hindgut. Term either applied to relatively short section of digestive tract near origin of midgut ceca or considered to be represented by midgut ceca themselves. [Stachowitsch, 1992]
- Elongate section of digestive tract between stomach and hindgut. Extends through most of thorax and abdomen. [Stachowitsch, 1992]
- Narrow section of digestive tract between posterior division of stomach (pyloric stomach) and hindgut; extends through posterior somites of thorax and through abdomen. Give rise anteriorly to pair of digestive glands. [Stachowitsch, 1992]
- (Taxon-specific: Class Secernentea) Elongate section of digestive tract between foregut and hindgut. May bear one to several pairs of midgut ceca anteriorly and pair of rectal ceca posteriorly. [Stachowitsch, 1992]
- (Taxon-specific: Order Monhysterida) Region of digestive tract in thorax between foregut (esophagus) and hindgut. One may distinguish an anterior crop and posterior intestine. Gives rise anteriorly to pair of highly branched ceca. [Stachowitsch, 1992]
- (Taxon-specific: Order Rhabditida) Elongate, somewhat extended (in barnacle, U-shaped) section of digestive tract between esophagus and hindgut; bears digestive ceca. Expanded region of midgut may be termed stomach. [Stachowitsch, 1992]
- Region of digestive tract between foregut (stomodeum) and hindgut (protocdeum). Extends throughout most of thoracoabdomen and lacks diverticula; with folded, relatively thick walls anteriorly, thinner walls posteriorly. [Stachowitsch, 1992]
- Region of digestive tract between foregut and hindgut. Extends through most of body and may be divided into expanded anterior stomach and more tube-like posterior section. [Stachowitsch, 1992]
- Region of digestive tract between foregut and hindgut. Extends through most of body and may be divided into expanded stomach and narrower intestine. Bears ceca. [Stachowitsch, 1992]
- Elongate section of digestive tract between foregut and hindgut; extends through trunk and bears pair of lateral diverticula in each segment. [Stachowitsch, 1992]
- Elongate section of digestive tract between stomach and hindgut. Extends through thorax and abdomen, giving rise anteriorly to series of ceca and posteriorly (at level of first and fifth pleomeres) to additional dorsal ceca. [Stachowitsch, 1992]
- Elongate section of digestive tract between stomach and anus. Extends through most of body. Digestive ceca open into digestive tract at border of stomach and midgut. [Stachowitsch, 1992]
- Elongate section of digestive tract between stomach and hindgut. Gives rise to pair of small dorsal ceca and pair of large ventral hepatic glands. [Stachowitsch, 1992]
