Comparative Image of human lumbar vertebrae (A) and canine lumbar vertebrae (B), showing anatomical differences between spines. These mammillary processes serve as attachment The neural process of the remaining thoracic vertebrae (as well as of the lumbar vertebrae) also inclines anteriorly and increases in height. But, you will not find this extra process in the structure The accessory processes are located between the transverse and the caudal articular processes of the last thoracic vertebrae (carnivores and pigs) and the lumbar vertebrae (carnivores). 6 In Oppenheimer ossicles are accessory ossicles associated with the facet joints and are found in ~4% (range 1-7%) of lumbar spines 1. There are 7 cervical The transverse process of a lumbar vertebra is also called costal or costiform process, because it corresponds to a rudimentary rib (costa) which, as opposed to the thorax, is not developed in The pedicle screw is one of the most common medical devices used in spinal surgery.
