Bone: Mammillary process

A lumbar vertebra from above and behind. (Mammillar process labeled at center left.)
Latin	processus mammillaris
Gray's	subject #23 106

Of the three tubercles noticed in connection with the transverse processes of the lumbar vertebrae, the superior one is connected in the lumbar region with the back part of the superior articular process, and is named the mammillary process.

Attachments of mammillary process: The multifidi muscle attaches to the mammillary process and helps to stabilize the vertebral joints. It spans from the sacrum to the cervical, endowing stability to each segmental level.
