Because the spinal cord ends so high up, nerves exiting the cord to provide control and sensation to the tail, hind legs, urinary bladder, large intestine, and anus must extend long branches to reach their destinations. Unfortunately, injuries to the tail can still cause serious nerve damage. The spinal cord itself does not extend down to the tail (it typically ends at the level of the fifth lumbar vertebra) which means that injuries to the tail do not damage the actual spinal cord. Order to serve the body parts to the rear of The spinal cord must stretch out behind in The spinal cord ends around the level of theĥth lumbar vertebra. The tail attaches to the body at an area called “the tail head.” The first caudal vertebra attaches to a special backbone called “the sacrum” which connects the tail and lower back (“lumbar”) vertebrae. The tail consists of a varying number of vertebrae (called “caudal” vertebrae) and voluntary muscles with ligaments and tendons holding it all together. Tails are wonderful, expressive body parts used by cats for communication purposes as well as for balance. The cat in this radiograph has a dislocation of the tailīetween the first and second caudal vertebrae (see flashing red arrows).Īlso note the distended urinary bladder (flashing yellow dotted line). (Also called "Sacrocaudal Fractures in the Cat")
