diaphysis

Subdivision of long bone which forms the part of the bone between the two epiphyses, excluding the metaphyses[FMA,modified]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the diaphysis is

Subdivision of long bone which forms the part of the bone between the two epiphyses, excluding the metaphyses[FMA,modified]. The atlas records it as a bone at the organ scale in the human body.

Where the diaphysis is

It sits within the skeletal system. Only the system is known. The position shown carries almost no spatial information.

What the diaphysis connects to

The atlas records 12 typed relationships for it, across 3 kinds of connection. a kind of zone of long bone.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the diaphysis. 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 body of long bone, long bone diaphysis and shaft of long bone. Searching any of those names reaches this page.

Questions

Where is the diaphysis?

It sits within the skeletal system. Only the system is known. The position shown carries almost no spatial information.

What does the diaphysis connect to?

A kind of: zone of long bone.

Is the diaphysis 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.
