Abstract

The study was conducted to record the structural and functional anatomy of chevron bone and os penis in dogs. The chevron bone along with coccygeal vertebra and os penis were collected from four adult dogs by natural wet maceration technique. The chevron bone was alphabet capital “V” or “Y” shaped bone which consisted of three processes namely, two lateral process and one ventral process. The two lateral processes were articulated with the haemal process of coccygeal vertebrae to form haemal canal. The chevron bones functionally protect the middle coccygeal artery which has important clinical role in assessing the animal health. The os penis was a heterotrophic bone situated inside the penis. It was triangular in outline with a base, a body and an apex. The body consisted of three surfaces and three borders. The ventral surface was made up of deep urethral sulcus which accommodated and protected the urethra.
