neural arch

Posterior part of a vertebra that consists of a pair of pedicles and a pair of laminae, and supports seven processes: four articular processes, two transverse processes one spinous process[WP]. ZFA: A neural arch encloses the neural canal and typically meets its partner to form a neural spine. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the neural arch is

Posterior part of a vertebra that consists of a pair of pedicles and a pair of laminae, and supports seven processes: four articular processes, two transverse processes one spinous process[WP]. ZFA: A neural arch encloses the neural canal and typically meets its partner to form a neural spine. The atlas records it as a bone at the organ scale in the human body.

Where the neural arch is

It sits within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the neural arch connects to

The atlas records 14 typed relationships for it, across 5 kinds of connection. part of vertebra.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the neural arch. 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 vertebra neural arch, arcus vertebra, arcus vertebrae, arcus vertebrae (vertebralis), dorsal arcocentrum and vertebra dorsal arch. Searching any of those names reaches this page.

Questions

Where is the neural arch?

It sits within the skeletal system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the neural arch connect to?

Part of: vertebra.

Is the neural arch 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.
