Gross Anatomy of Some Digestive Organs of the Domestic Canary (Serinus Canariа)

Abstract

PURPOSE:The domestic canary (Serinus canariа) is a widely spread representative of the largest avian order Passeriformis. The increased interest to canaries as pets, the scarce anatomical data and the frequently encountered digestive tract pathology are the motives of the present study. The purpose of the research was to investigate the normal anatomy and topography of some digestive organs of the domestic canary. MATERIALS AND METHODS:The corpses of 12 canaries at 2 years of age were investigated. The bodies were divided into 2 groups of 6 birds each. The birds from group I were dissected and anatomo-topographic features of some digestive organs were examined in situ. The obtained data were used in bodies from group II for determination of percutaneous anatomic projections of the gizzard, duodenum, ileum and the liver. The sternal margo caudalis, last pair of ribs and os pubis were used as bone markers for more precise projections. After determination of percutaneous projections of organs, the bodies of canaries from group II were subjected to dissection for comparison of anatomical findings. RESULTS:The anatomo-topographic features of some digestive organs of the domestic canary and associated normal anatomic percutaneous projections were determined and documented. CONCLUSION: The results could serve for macroscopic in vivo and pathoanatomical diagnostic studies, as well as for prophylaxis of digestive organs' illnesses.

Morphological description of the alimentary canal and adnexal glands in Amazilia tzacatl, Amazilia saucerottei, Amazilia amabilis and Anthrachotorax nigricollis species

“…The stomach of hummingbirds displays a distinct topographic and microstructural anatomy that facilitates the differentiation between the proventriculus and ventriculus. Similar characteristics have been observed in other insectivorous bird species (Hristov et al., 2017). In carnivorous birds, there is typically no significant difference among stomach segments, whereas nectarivores species generally show an intermediate level of differentiation (Hristov et al., 2017).…”

Large intestine in pheasant (phasianus colchicus) and see‐see partridge (ammoperdix griseogularis). A comparative morphological and histological study

“…Cecum in eagles, hawks, vultures, crows, seagulls and other Falconiformes is also absent or remains in a tiny size (0–2 cm) (Dyce, 2018; Igwebuike & Eze, 2010;). In the canary, cecum and rectum are also very small compared to other parts of the gastrointestinal tract (Hristov et al, 2017). The evolution of cecum in birds seems to be related to the bird's dietary proclivities.…”

Computed tomographic features of the normal spleen in rabbits (Oryctolagus cuniculus domesticus)

“…Therefore, safe bandaging and securing of the catheter is essential and was performed for all patients in this study. In our institution, we have encountered a number of rabbits with splenic abnormalities and diseases; however, there is very limited information available on the morphology of the rabbit spleen 7–11 . The authors could not find any information about the CT anatomy of the rabbit spleen.…”
