superior colliculus in dogs

Part of the midbrain tecturm consisting of paired bodies that sit caudal to the thalamus and surround the pineal gland in the mesencephalon of vertebrate brains. It comprises the rostral aspect of the midbrain, posterior to the periaqueductal gray and adjacent superior the inferior colliculus. The inferior and superior colliculi are known collectively as the corpora quadrigemina (Latin, quadruplet bodies). It consists of several identified cellular layers and also comprises the brachium of the superior colliculus and commissure of supeior colliculus from Wikipedia.org and Neuronames (MM). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the superior colliculus is

Part of the midbrain tecturm consisting of paired bodies that sit caudal to the thalamus and surround the pineal gland in the mesencephalon of vertebrate brains. It comprises the rostral aspect of the midbrain, posterior to the periaqueductal gray and adjacent superior the inferior colliculus. The inferior and superior colliculi are known collectively as the corpora quadrigemina (Latin, quadruplet bodies). It consists of several identified cellular layers and also comprises the brachium of the superior colliculus and commissure of supeior colliculus from Wikipedia.org and Neuronames (MM). The atlas records it as a nerve at the organ scale in the dog.

Where the superior colliculus 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 superior colliculus connects to

The atlas records 12 typed relationships for it, across 3 kinds of connection. part of anatomical entity, anatomical system and brain, and 3 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the superior colliculus. 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 colliculus, anterior corpus quadrigeminum, cranial colliculus, optic tectum, colliculus bigeminalis oralis and colliculus cranialis, and 14 more. Searching any of those names reaches this page.

Questions

Where is the superior colliculus?

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 superior colliculus connect to?

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

Is the superior colliculus 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.
