The ventral lateral sacrocaudal is a long strong muscle consisting of numerous individual parts. Its first segment originates from the last lumbar vertebrae and the remainder from the transverse processes of the caudal vertebrae. From the segmented bellies arise long tendons which are embedded in caudal fascia. The first of these tendons inserts onto the sixth caudal vertebrae, the second onto the seventh and so on until the last caudal vertebrae. The ventral lateral sacrocaudal acts to flex the tail and occasionally assists with lateral movement.
