- n. Plural form of parapophysis.
Sorry, no etymologies found.
The positions of the parapophyses and diapophyses change along the length of the vertebral column, and indeed their relative positions allow us to identify where in the sequence an isolated vertebrae came from.
* In tetrapods with two-headed ribs, the more ventral rib head contacts a facet on the vertebra known as the parapophysis (plural parapophyses), while the more dorsal rib head contacts a facet known as the diapophysis (plural diapophyses).
The parapophyses are elliptical in outline and dorsoventrally taller than long, with their long axis inclined dorsally and posteriorly.
