“…Further, the expression of collagens at the serosa and submucosa was moderate in the lamina propria of the villi and minimal in the tunica muscularis. These observations suggest that collagen localization is involved in the transport and regulation of absorbed food promoted by rhythmic contraction of the muscularis muscle fibers (Al‐Saffar & Al‐Samawy, 2016; Pandit et al, 2018; Verma, Malik, Shrivastava, & Parmar, 1999).…”

We describe the functional morphology of the digestive tract of the Eurasian collared dove, Streptopelia decaocto using anatomical, morphometric, histological, histochemical, and ultrastructure techniques, and relate our findings to the species' dietary niche. Our results revealed that the esophagus is displaced on both sides of the neck and has highly folded tunica mucosa, which confer greater elasticity for efficient swallowing and passage of food to the crop. The proventriculus is delicate and its mucosal layer contains polymorphic glands with dense profound and superficial secretory units that open to the luminal surface by gastric pores. The ventriculus is biconvex and lined with a keratinized koilin membrane. The tubular glands within the mucosal lining include the isthmus, the neck, and the basal segment that comprise chief and basal cells with prominent nuclei. At the cuticle-mucosal interface, pyramidal vertical rodlets of the cuticle are secreted and superficially covered by a thin film of a horizontal matrix. The mucosa of the ileum form pyramidal villi that are oriented perpendicularly to the central lumen. Enterocytes infiltrated with goblet cells make up the epithelial lining of the villi. There are subtle differences in the thicknesses of corresponding tunics together with histochemical reactions of alcian blue (AB) and Masson-Goldner trichrome (MT) for their microstructures. Overall, our findings reveal remarkable convergence of both macro-and microstructures in S. decaocto to other granivorous species, and offer further evidence of the close association between functional morphology and feeding style relative to food swallowing, digestion, and absorption.

“…Some researchers point to its presence: in domestic hens (Casteleyn et al, 2010;Kuleshov, 2010;Pandit et al, 2018), in the African pied crow (Igwebuike & Eze, 2010), in the domestic goose (Liu et al, 2010), striated scope owls (Otus brucei) (Al-Saffar & Al-Samawy, 2016), guinea fowl (Singh et al, 2017), others point to its absence in domestic hens (Hodges & Michael, 1975;Gabella, 1985;Kachave et al, 2009). The mulard has sufficiently thick LMM which contain a large number of blood vessels (Eyhab et al, 2017).…”

“…The LMM of large intestine has the form of longitudinally oriented bundles of unstriated muscle cells, which stretch in the folds in form of vertical pillars in the African pied crow (Corvus albus) (Igwebuike & Eze, 2010), cattle egret (Bubulcus ibis) (Hussein & Rezk, 2016) and domestic hen (Pandit et al, 2018). The LMM of the goose rectum is divided by layers of loose connective tissue, which consist of nerve elements, whereby it is double-layer (Strizhikov et al, 2007).…”

The aim of work was to determine the features of the microscopic structure of the lamina muscularis mucosae of the goose gut during the postnatal ontogenesis. According to the review of the literature, during the characterisation of the structure of the intestinal mucosa, researchers first pay attention to the condition of the villi, crypts, epithelial layer and their morphometric parameters, leaving the lamina muscularis mucosae aside. The intestinal lamina muscularis mucosae is an under-researched structure of the intestinal wall, the information on which is fragmentary and contradictory. The middle parts of the duodenum, jejunum, ileum, cecum and rectum of large grey geese of 13 age groups were investigated. The classic histological methods of staining by hematoxylin and eosin, aniline blue – orange (by Mallory), as well as azure II – eosin were used. It was established that the lamina muscularis mucosae of the goose’s small intestine is formed by two layers of unstriated muscle tissue: internal and external. In contradistinction to mammals, the thicker inner layer of the LMM has not a circular, but a longitudinal direction of cell location while by contrast the thinner outer layer is located in a circular direction. According to results of our research, the thickness of the lamina muscularis mucosae of the small intestine of the geese rapidly increased with age. The thickness of the duodenum corresponded to the value of adult geese at 60 days of age; jejunum, ileum, and rectum – at 21 days, cecum – at 7 days age. The lamina muscularis mucosae was thinnest in the duodenum, and it was thickest in the ileum. The lamina muscularis mucosa of the large intestine of geese is represented by only one longitudinal layer. By contrast, the thinner outer layer is located in a circular direction. Detailed information of the microscopic structure of the lamina muscularis mucosae of the intestine of geese can be useful for specialists, both morphologists and physiologists, for analyzing the histological preparations of the intestine of birds by the action of biotic and abiotic factors, as well as a basis of comparison with such structure in other species of animals. The description of the construction of this important microscopic structure of the intestine can serve a morphological basis for elucidating its function.

“…It also accumulates biologically active substances, immune cells (Casteleyn et al, 2010;Revajova et al, 2013), and blood vessels and nerves lie across it. Connective tissue in general and its fiber component in particular is a part of the trophic complex of a certain area (Zeng et al, 2003;Pandit et al, 2018). For this reason, connective tissue is considered to play an important role in formation of homeostasis (Borda-Molina et al, 2018;Kogut et al, 2018).…”

The connection between the separate structural parts of the mucous membrane of the small intestine of laying hens and the typological features of the autonomic tone were investigated. The studies were conducted on adult chickens of the cross-breed "Isa-Brown", which were divided into two groups: sympathicotonic chickens and sympathico-normotonic chickens, by the methods of electrocardiography and variation-pulsometry research. In the small intestine of the poultry of each group, the linear dimensions were determined first, and then the volume of the entire mucous membrane and its separate parts (villi, crypt, muscular plate), as well as the volume of connective tissue fibers in the crypt region. Research has shown that the villi account for ¾ of the volume of the entire mucous membrane. The volume of villi in the entire small intestine is more important in sympathico-normotonic chickens. This same poultry group has an advantage in the indicators of the volume of the muscular plate, but only in the duodenum and jejunum. In indicators of crypt volume, it turned out to be quite the opposite of the relationship with the typology of autonomous influences. In all studied intestines, the higher values of this indicator belong to the sympathotonic chickens. However, in terms of the volume of the entire mucous membrane, larger values still correspond to sympathico-normotonic chickens. Sympathicotonic chickens are inferior to them in the duodenum – at 1,005 mm3, in the jejunum – at 2,699 mm3 and in the ileum – only 78 mm3. Investigating the structure of the villi, we established that the volume of their epithelium in all three sections of the small intestine has higher values in the sympathico-normotonic chickens, and the larger volume of the lamina propria of the villi in the sympathicotonic chickens. At the same time, the connection with the type of autonomic tone is reflected in the ratio between the two layers of villi. In all three sections of the small intestine of sympathicotonic chickens, the ratio between the epithelium and the lamina propria was, on average, 65%/35%, or 2/1. In sympathico-normotonic chickens, this ratio varied and, on average, equalled 75%/25%, or 3/1. The increase in the tone of sympathetic centers contributes to the growth of volume both as the total amount of fibers of connective tissue, and also as separate elastic fibers in the area of crypt. According to the data,indicators of the sympathico-normotonic chickens are inferior to those of sympathicotonic chickens in all of the small intestine. It was also found that in both groups of poultry the volume of elastic fibers was approximately half the volume of all fibers of the connective tissue of the duodenum. In other sections of the small intestine, this figure was reduced to about ⅓. Consequently, the typological features of the autonomic tone, providing various trophic-regulatory effects on the mucous membrane of the small intestine, cause the formation of differences in its volume.
