Its beginning is marked by the presence of two pyloric caeca
of different lengths.
The intestinal caeca
were almost straight and run longitudinally along the length of the body reaching the acetabular region.
Khantaphant S, Benjakul S (2010) Purification and characterization of trypsin from the pyloric caeca
of brownstripe red snapper (Lutjanus vitta).
The digestive tract of each fish was individually divided into five segments: stomach (ST), pyloric caeca
(PC), and intestine in three sections (proximal (PI), middle (MI) and distal intestine (DI).
These pouches are the "gastric caeca
" occasionally mentioned in the literature: however, their tissue lacks a differentiated luminal epithelium relative to the anterior midgut, nor do they harbor large quantities of symbiotic microbes, and thus may not be considered "true" caeca
(Beadle 1972, Shelomi et al.
Uterus consists of numerous loops, runs between testes and vitellarium to reach genital pore, loops rarely extend laterally beyond caeca
branched, extending posteriorly to peduncle base, not confluent.
This species, however, has fewer pyloric caeca
, and more pectoral fin rays.
Tegument spinose, to the level of intestinal caeca
He noted, "The contents of the crop are acid; the contents of the gizzard are more acid than those of the proventriculus; the contents of the duodenum and upper portion of the small intestine are less acid than the contents of the crop; the contents of the lower portion of the small intestine, caeca
and large intestine are approximately neutral.
In sea stars of both sexes, estrogens may promote biosynthesis of protein in the pyloric caeca
and its subsequent mobilization into the gonads (Schoenmakers and Dieleman, 1981; Voogt and Dieleman, 1984; Voogt et al.
48), and (iii) the low frequency of the phenomenon is surely another argument against the interpretation of nomina caeca
as noun and adjective in agreement at line-end at Silvae 2.
Anatomy and Histology of the Pyloric Caeca
in Five Species of Fish of the Characidae Family
The familiar characteristics of this family were: the presence of annular muscular thickness; sub-terminal oral sucker; caeca
simple and extending up to caudal end; esophagus absent or present; Cirrus pouch absent; testes are intracaecal or extracaecal located diagonally or symmetrically, in the second third of the body; ovary anterior to testes, vitellaria commencing at the level of the testes and parasitic in urinary tract of birds (Kharoo, 2012).
The contents of the crop, gizzard, ileum, caeca
, and rectum were quantitatively collected.
