anterior commissure in dogs

A bundle of myelinated nerve fibers passing transversely through the lamina terminalis and connecting symmetrical parts of the two cerebral hemispheres; it consists of a smaller anterior part (pars anterior commissurae anterioris) and a larger posterior part (pars posterior commissurae anterioris). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the anterior commissure is

A bundle of myelinated nerve fibers passing transversely through the lamina terminalis and connecting symmetrical parts of the two cerebral hemispheres; it consists of a smaller anterior part (pars anterior commissurae anterioris) and a larger posterior part (pars posterior commissurae anterioris). The atlas records it as a nerve at the organ scale in the dog.

Where the anterior commissure is

It sits within the nervous system. Not positioned individually, and containment is not asserted either. Drawn near structures of the same kind, which is a weak claim about location.

What the anterior commissure connects to

The atlas records 6 typed relationships for it, across 3 kinds of connection. a kind of intercerebral commissure and ventral commissure.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the anterior commissure. 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 anterior cerebral commissure, commissura anterior cerebri, commissura rostralis, AC, anterior commissural nucleus and commissura anterior, and 4 more. Searching any of those names reaches this page.

Questions

Where is the anterior commissure?

What does the anterior commissure connect to?

A kind of: intercerebral commissure and ventral commissure.

Is the anterior commissure 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.
