Ossa cordis and os aorta in the one‐humped camel: Computed tomography, light microscopy and morphometric analysis

Abstract

The present study describes the morphological characteristics of the camel heart Ossa cordis, and os aorta using computed tomography soft tissue window (CT) alongside 3D render volume reconstructions and light microscopy. The current study techniques demonstrated the Ossa cordis and os aorta in the cardiac window with more precision than the black and white (ghost), and angiography images. Transverse and sagittal CT images additionally demonstrated the presence of Ossa cordis and os aorta. This study is the first to record two small Ossa cordis sinistrum and one os aorta in the camel heart, in addition to the more commonly observed singular, large, os cordis dextrum. The os cordis dextrum was always located in the upper part of the interventricular septum, near to its junction with the atrium, forming an elongated rectangular shape when observed transversally. The wider cranial part was composed from bone, whereas the caudal aspect was narrow and contained both bone and cartilage. Light microscopy identified that the os cordis dextrum consisted of trabecular bone, marrow spaces, and hyaline cartilage.Two Ossa cordis sinistrum were detected on the left side of the heart, one in the right fibrous ring and another in the interventricular septum, microscopy showed that both contained only trabecular bone with osteocytes, osteoblasts, and osteoclasts. At the level of ascending aorta, there was also trabecular bone containing osteocytes, an os aorta.

Investigating the role of Purkinje fibers and synaptic connectivity in balance regulation through comprehensive ultrastructural and immunohistochemical analysis of the donkey's (Equus asinus) cerebellum

“…To visualize the cellular structures, the sections were stained using the hematoxylin and eosin staining technique, following the established protocols outlined by Bancroft and Gamble (2008). ImageJ software was used for measurements from the figures (Alsafy & El‐Gendy, 2022; Alsafy et al, 2021; El‐Gendy et al, 2023; Ez Elarab et al, 2022).…”

Macro‐ and micro‐morphological comparison of the detailed structure of the oral cavity roof in two different feeding habits marine fishes: Pagrus pagrus and Boops boops

“…The tissue samples were then cleared with xylene and embedded in paraffin. The sample sections were cut transversally at 6 μm were prepared using a Reichert Leica RM 2125 Microtome, and mounted on glass slides (El‐Gendy, Alsafy, et al, 2023; El Sharaby et al, 2012; Ez Elarab et al, 2022). After deparaffinization in xylene, tissue sections were stained with hematoxylin‐eosin stain.…”

Decellularization and characterization of camel pericardium as a new scaffold for tissue engineering and regenerative medicine

“…Considering that camel is raised and used as a food source in many countries, the use of its different tissues can be considered as an option in regenerative medicine. Although some studies investigated the cardiovascular properties of camels, [8][9][10] the camel pericardium (CP) characteristics has been poorly described. Furthermore, camels strongly resist many viral and microbial infections, including foot-and-mouth disease, tetanus, and mad cow disease which makes it a favorable agent for tissue engineering-related studies.…”
