Gross Anatomical Studies on the Os-coxae and Synsacrum of Japanese Quail (Coturnix coturnix japonica)

Abstract

The present study was conducted on pelvic girdle and synsacrum of Japanese quail. The pelvic girdle was extremely thin and delicate. Average length of ilium was 3.70 ±0.13 cm in which pre-acetabular and postacetabular parts were measured 2.20±0.11 cm and 1.5±0.06 cm, respectively. The dorsal surface of pre-acetabular part was deeply concave and post-acetabular part was convex. The ischium was irregularly triangular in shape. The pubis was a thin rod-like bone measured 2.5±0.12 cm followed the ventral border of the ischium and projected beyond caudally. The middle portion of pubis was fused with the ventral border of ischium, which divided the incisura puboischiadica into an anterior foramen obturatum and a caudal slit. Lumbosacral mass was consisted of 10 vertebrae. Synsacrum was composed of 12 vertebrae including last thoracic vertebra, lumbo-sacral mass and first coccygeal vertebra.
