The sternal spine was very short (< 2mm) and thick, and arose from the middle of the cranial border. The corpus sterni was quadrilateral in shape and 1.9 cm long. The dorsal surface of the sternum was deeply concave and narrow in the cranial half, broad and less concave in the caudal half. A groove was present in the centre of the dorsal surface, and it contained a large pneumatic foramen at the beginning. The foramen ovale or the incisura ovalis was absent. The craniolateral angle showed the 0.3 cm long craniolateral processes. The lateral borders showed five articular cylinders for the ventral ends of sternal ribs. The caudolateral processes and the thoracic processes were absent. The caudal border was convex, wide (1.3 cm) and did not show incisure. The sternal crest was very prominent.ArticleItem Open Access Gross Morphological and Morphometrical Studies on the Sternum of Asian Koel (Eudynamys scolopaceus)(2020) Sathyamoorthy, OR; Palanivelrajan, M; Ushakumary, S; Sreekumar, C; TANUVASABSTRACT Background: The sternum is one of the most important and characteristic skeletal elements in birds, highly adapted for flight and showing a diverse range of morphogenesis. The Asian koel (Eudynamys scolopaceus) is a member of the Cuckoo order of birds, found in the Indian sub-continent, China and Southeast Asia. The present study was carried out as anatomical data on the sternum of this species is scanty. Methods: Carcass of Asian koel brought to the Department of Wildlife Science, Madras Veterinary College, Chennai after the postmortem examination was biologically macerated, cleaned, dried and morphological and morphometric studies were performed. Result: Gross morphological and morphometric data of the sternum of Asian koel was compared with other avian species. The sternum of Asian koel was large, broad, quadrilateral shaped and highly pneumatized bone with well developed sternal crest, craniolateral and caudolateral processes. These features provide protection to the viscera and facilitates superior flight.ArticleItem Open Access Gross Morphological Studies on the Pelvic Girdle of Spot-Billed Pelicans (Pelecanus philippensis)(2012-12) Sathyamoorthy, OR; Thirumurugan, R; Senthil Kumar, K; Jayathangaraj, MG; TANUVASThe pelvic bone consisting of ilium, ischium and pubis were fused with each other and also with the transverse and spinous processes of synsacral vertebrae. The fossa renalis was shallow. In the post-acetabular part, the dorsal surface had 7 or 8 openings on either side of the median ridge. The perforated acetabulum was formed by all the three bones. The anti-trochanter was present caudo-dorsal to the acetabulum. The cranial part of ischium was a thick rod-like portion. The caudal part of ischium was quadrilateral in shape. The ischiatic foramen was an elongated, large and oval shaped. Incisura pubo-ischiadia was long. The pubis was a thin, rib-like bony rod and projected caudally beyond the ischium. The processus pectinealis was absent.ArticleItem Open Access Micro Anatomical Studies on the Moderator Band of Spotted Deer (Axis axis)(2019-11) Sathyamoorthy, OR; Ushakumary, S; Thangapandian, M; TANUVASAbstract The moderator bands of the spotted deer consisted of an outer endocardial covering, ordinary myocardial bres, Purkinje bres, blood vessels and nerve bres. The endocardium was thick dorsally and thin laterally and ventrally. The Purkinje bres were large, round or polygonal cells present as a large group below the subendocardium or within the myocardium. The central core of the moderator band was formed by myocardium.ArticleItem Open Access MORPHOLOGICAL AND MORPHOMETRIC STUDIES ON THE PELVIC GIRDLE OF CHINESE GOOSE (ANSER CYGNOIDES)(2020-07) Sathyamoorthy, OR; Richard Chruchil, R; Dhamotharan, S; TANUVASThe pelvic girdle of Chinese goose was a large, elongated bone, narrow cranially (3.0 cm) and wide (8.0 cm) caudally. It consisted of two os coxae, each of which was made up of an ilium, an ischium and a pubis. The ilium of the Chinese goose was the largest and longest (14 cm) bone of the os coxae. The pre-acetabular part of the ilium was 6.80 cm long and 2.0 cm wide. The post-acetabular part of ilium was 7.2 cm long. The ilioneural canal was slightly broad in front and narrow caudally.The pelvic surface of ilium showed six openings on either side of the bodies of the lumbosacral mass. The ischiatic foramen was 3.60 cm long and 1.20 cm wide. The ischium was triangular in shape and 7.50 cm long. The caudal border of the pelvis was wide (7.50 cm) and showed a deep notch. The pubis was long (12.0cm), thin, bent rod-like bone, projected well beyond the caudal border of the os coxae and bent medially. The pectineal process was short and rounded. Pneumatic foramina were absent in the os coxae of the Chinese goose. The acetabulum was large and formed by all the three bones. The anti-trochanter was quadrilateral in shape and prominent.ArticleItem Open Access Morphological and Morphometrical Studies on the Sternum of Chinese Goose (Anser cygnoides)(2020-07) Sathyamoorthy, OR; Richard Chruchil, R; Sangilimadan, K; Dhamotharan, S; TANUVASThe sternum of Anser cygnoides consisted of a manubrium sterni, a corpus sterni and a sternal crest. The manubrium sterni is very small, flat and extended only from the middle of the ventral lip of the cranial border. The corpus sterni is large, quadrilateral, broad in the cranial two thirds and narrow in the caudal one third. The dorsal surface showed numerous pneumatic foraminae. An elongated deep transverse articular groove is seen in cranial border. The craniolateral processes are thin, short and broad. Seven articular cylinders and the troughs between them containing large pneumatic foraminae are seen at the lateral borders. The processes thoracicus was absent. The caudolateral processes extended beyond the caudal border of the sternum and enclosed along with the lateral border of the corpus sterni, the incisura ovalis. The sternal crest was prominent, projected from below the sternal spine, and ended before the caudal border.
