Anatomical description of a new ligamentous supporting structure of the canine cranial cervical spinal cord

The cranial cervical vertebral column carries a unique range of mobility with the addition of dorsal and ventral flexion and rotation. The denticulate ligaments provides support and protection of the spinal cord, but little is known of the adaption of this apparatus at the cranial cervical portion of the spinal cord. We present in this publication a new pair of ligaments in dogs that supports the spinal cord inside the vertebral canal at the level of the C1-C2 spinal segments.
