prezygapophysis

Paired processes at the cephalic end of the neural arch. The articular facets of the prezygapophyses face dorsomedially and articulate with the lateroventrally facing facets of the postzygapophyses of the preceding vertebra. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the prezygapophysis is

Paired processes at the cephalic end of the neural arch. The articular facets of the prezygapophyses face dorsomedially and articulate with the lateroventrally facing facets of the postzygapophyses of the preceding vertebra. The atlas records it as a bone at the organ scale in the human body.

Where the prezygapophysis is

It sits within the skeletal system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the prezygapophysis connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. a kind of zygapophysis.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the prezygapophysis. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as cranial articular process of vertebra, prezygapophysis, processus articularis superior, processus articularis superior vertebrae, superior articular process of vertebra and vertebra cranial articular process, and 4 more. Searching any of those names reaches this page.

Questions

Where is the prezygapophysis?

It sits within the skeletal system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What does the prezygapophysis connect to?

A kind of: zygapophysis.

Is the prezygapophysis the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
