Abstract

The spinal cord segments forming the lumbosacral enlargement in duck, pigeon and chicken are vascularized by the segmental spinal branches which originate regularly from the lumbar and sacral arteries of the descending aorta. The lumbosacral part of the spinal cord of birds is characterized by the presence of the Fossa rhomboidalis spinalis which contains the Corpus gelatinosum. The pattern of arterial distribution at the level of the sinus rhomboidalis differ from that found elsewhere in the spinal cord.
