Century Dictionary and Cyclopedia
    • n metapophysis In anat, a dorsolateral apophysis developed on the prezygapophysis or anterior articular process of a vertebra, especially in the lumbar region. It corresponds to the inner tubercle of the diapophysis of a thoracic vertebra. It is sometimes very highly developed, as in the armadillo, when it assists in the support of the carapace. In man, in whom it is rudimentary yet is endogenous or enveloped from an independent center of ossification, it is found in the lumbar region, as the mammillary process or mammillary tubercle. See cut under lumbar.
