midbrain tectum in dogs

Dorsal part of the midbrain, consisting of the superior and inferior colliculi and the pretectal nuclei (MM). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the midbrain tectum is

Dorsal part of the midbrain, consisting of the superior and inferior colliculi and the pretectal nuclei (MM). The atlas records it as a nerve at the organ scale in the dog.

Where the midbrain tectum 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 midbrain tectum connects to

The atlas records 12 typed relationships for it, across 4 kinds of connection. part of anatomical entity, brain and midbrain, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the midbrain tectum. 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 mesencephalic tectum, neuraxis tectum, tectum, tectum mesencephali, t. mesencephali and tectum mesencephalicum, and 1 more. Searching any of those names reaches this page.

Questions

Where is the midbrain tectum?

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 midbrain tectum connect to?

Part of: anatomical entity, brain, midbrain and nervous system.

Is the midbrain tectum 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.
