Gross Anatomical Studies on the Sternum of Brown Wood Owl (Strix leptogrammica)

Abstract

The present study was designed to elucidate the morphological characteristics of sternum of brown wood owl. The sternum was a thin, flat bone with a body, rostrum and keel. The body was quadrilateral plate with concave dorsal and convex ventral surfaces and four borders. The dorsal surface presented three prominent
pneumatic foramina at the cranial end. The lateral border on either side had five articular facets for sternal ribs. The triangular pointed craniolateral process long caudolateral processes on either side. A well developed triangular keel was located along midline of the ventral surface of the body of sternum.
