myelencephalon in dogs

The posterior part of the developing vertebrate hindbrain or the corresponding part of the adult brain composed of the medulla oblongata and a portion of the fourth ventricle; as well as the glossopharyngeal nerve (CN IX), vagus nerve (CN X), accessory nerve (CN XI), hypoglossal nerve (CN XII), and a portion of the vestibulocochlear nerve (CN VIII).[BTO,WP]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the myelencephalon is

The posterior part of the developing vertebrate hindbrain or the corresponding part of the adult brain composed of the medulla oblongata and a portion of the fourth ventricle; as well as the glossopharyngeal nerve (CN IX), vagus nerve (CN X), accessory nerve (CN XI), hypoglossal nerve (CN XII), and a portion of the vestibulocochlear nerve (CN VIII).[BTO,WP]. The atlas records it as a organ at the organ scale in the dog.

Where the myelencephalon is

It sits within the nervous 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 myelencephalon connects to

The atlas records 18 typed relationships for it, across 5 kinds of connection. part of hindbrain, nervous system and organ.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the myelencephalon. 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 myelencephalon (medulla oblongata). Searching any of those names reaches this page.

Questions

Where is the myelencephalon?

It sits within the nervous 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 myelencephalon connect to?

Part of: hindbrain, nervous system and organ.

Is the myelencephalon 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.
