prezygapophysisn.

Brit.

/ˌpriːzʌɪɡəˈpɒfᵻsɪs/, U.S.

/ˌprizaɪɡəˈpɑfəsəs/

Inflections: Plural prezygapophyses.

Origin: Formed within English, by derivation. Etymons: pre- prefix, zygapophysis n.

Etymology: < pre- prefix + zygapophysis n. Compare postzygapophysis n., prozygapophysis n. at pro- prefix² 2a.In quot. 1851 at main sense, prezygapophyses appears to be an error for prozygapophyses , which was coined by Owen in the same paper (see quot. 1851 for prozygapophysis n. at pro- prefix² 2a). Prezygapophyses was, however, retained in the account of this paper in Abstr. Papers Royal Soc. 6 (1854) 11.

Zoology and Anatomy.

Either of the two (left and right) anterior or superior articular processes of the neural arch of a vertebra, which articulate with the postzygapophyses of the previous vertebra. Also: either of two anterior articular processes on the haemal arch of certain fishes.

1851 R. Owen in Philos. Trans. (Royal Soc.) 141 725 The metapophyses are well developed and project midway between the diapophyses and prezygapophyses on the eleventh dorsal.

1865 Philos. Trans. (Royal Soc.) 155 62 The anterior oblique process or ‘prezygapophysis’ of the seventh cervical vertebra.

1930 H. G. Newth Marshall & Hurst's Junior Course Pract. Zool. (ed. 11) xiii. 296 The pre-zygapophyses, or anterior articular processes, project upwards from the anterior end of the neural arch.

1974 D. Webster & M. Webster Compar. Vertebr. Morphol. xv. 380 These muscles arise from the surface of each prezygapophysis and extend obliquely and caudally to insert on the anterior surfaces of the ribs.

2002 Aquaculture 211 312 The haemal arches similarly exhibited an anterior haemal prezygapophysis and a posterior haemal poszygapophysis.

1883 Proc. Amer. Philos. Soc. 1882–3 20 454 There are prezygapophysial facets, but the postzygapophyses exist.

1937 Trans. Amer. Philos. Soc. 30 331 The tubercular articular facet is entirely below the prezygapophysial surface.

1961 Amer. Midland Naturalist 66 459 The prezygapophysial articular facets are oval.

1990 Philos. Trans. (Royal Soc.) B. 328 236 The axis..has a nearly circular centrum in cross-section, and there is a long prezygapophyseal, and a curved postzygapophyseal, process.
