diapophysis Anat.|daɪəˈpɒfɪsɪs|
Pl. -physes.
[f. Gr. δια- through, apart + ἀπόϕυσις offshoot, apophysis.]
A term applied by Owen to a pair of exogenous segments of the typical vertebra, forming lateral processes of the neural arch.
In the cervical vertebræ of man and other mammals it is represented by the posterior part of the ring enclosing the vertebral artery; in the dorsal vertebræ by the transverse process; in the lumbar and sacral vertebræ by short processes of the centrum (Syd. Soc. Lex.).
1854Owen Skeleton in Circ. Sc. Organ. Nat. I. 168 The neural arch..also sometimes includes a pair of bones, called ‘diapophyses’. 1872Mivart Elem. Anat. vi. (1873) 220 We may thus distinguish two series of paraxial parts on each side, one made up of tubercular processes (or diapophyses) and ribs, and the other made up of capitular processes (or parapophyses) and ribs.
Hence diapoˈphysial a., of or belonging to a diapophysis.
1854Owen in Circ. Sc. Organ. Nat. I. 206 The bones..manifest more of their diapophysial character than their homotypes do in the occipital segment. |
