oculomotor nuclear complex in dogs

Nuclear complex containing subnuclei that give rise to the axons of the occulomotor nerve, both motor and parasympathetic fibers, situated at the midline at the level of the superior colliculus in the midbrain tegmentum (Brodal, Neurological Anatomy, 3rd ed., 1981, pg 533-534). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the oculomotor nuclear complex is

Nuclear complex containing subnuclei that give rise to the axons of the occulomotor nerve, both motor and parasympathetic fibers, situated at the midline at the level of the superior colliculus in the midbrain tegmentum (Brodal, Neurological Anatomy, 3rd ed., 1981, pg 533-534). The atlas records it as a nerve at the organ scale in the dog.

Where the oculomotor nuclear complex 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 oculomotor nuclear complex connects to

The atlas records 4 typed relationships for it, across 2 kinds of connection. part of midbrain and midbrain tegmentum.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the oculomotor nuclear complex. 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 OM, nucleus nervi oculomotorii, nucleus of oculomotor nerve, nucleus of oculomotor nuclear complex, nucleus of third cranial nerve and oculomotor III nuclear complex, and 7 more. Searching any of those names reaches this page.

Questions

Where is the oculomotor nuclear complex?

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 oculomotor nuclear complex connect to?

Part of: midbrain and midbrain tegmentum.

Is the oculomotor nuclear complex 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.
