ischium in dogs

Endochondral bone that is paired, forming the posterior part of the pelvis, articulating with the pubis and ilium. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the ischium is

Endochondral bone that is paired, forming the posterior part of the pelvis, articulating with the pubis and ilium. The atlas records it as a bone at the organ scale in the dog.

Where the ischium is

It sits in the pelvis and trunk, within the skeletal system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the ischium connects to

The atlas records 15 typed relationships for it, across 6 kinds of connection. part of anatomical entity, innominate bone and pelvic girdle skeleton, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the ischium. 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 ischial bone, ischium bone and os ischii. Searching any of those names reaches this page.

Questions

Where is the ischium?

It sits in the pelvis and trunk, within the skeletal system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What does the ischium connect to?

Part of: anatomical entity, innominate bone, pelvic girdle skeleton and bony pelvis.

Is the ischium the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
