parvocellular oculomotor nucleus in dogs

Nucleus that is part of the oculomotor nerve complex consisting of preganglionic parasympathetic neurons situated close to the midline at the level of the superior colliculus (Heimer, the Human Brain and Spinal Cord, 1994, pg 244). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the parvocellular oculomotor nucleus is

Nucleus that is part of the oculomotor nerve complex consisting of preganglionic parasympathetic neurons situated close to the midline at the level of the superior colliculus (Heimer, the Human Brain and Spinal Cord, 1994, pg 244). The atlas records it as a nerve at the organ scale in the dog.

Where the parvocellular oculomotor nucleus 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 parvocellular oculomotor nucleus connects to

The atlas records 6 typed relationships for it, across 2 kinds of connection. part of central nervous system, midbrain and midbrain tegmentum.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the parvocellular oculomotor nucleus. 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 EW, PC3, Edinger-Westphal nucleus, accessory oculomotor nucleus, nucleus Edinger-Westphal and Edinger-Westphal nucleus of oculomotor nerve, and 8 more. Searching any of those names reaches this page.

Questions

Where is the parvocellular oculomotor nucleus?

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 parvocellular oculomotor nucleus connect to?

Part of: central nervous system, midbrain and midbrain tegmentum.

Is the parvocellular oculomotor nucleus 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.
