pineal body in dogs
A midline, cone like structure located in the dorso-caudal roof of the 3rd ventricle, attached by peduncles to the habenular and posterior commissures. The stalk contains nerve fibers, blood vessels, connective tissue and parenchymal cells (Paxinos, The Rat Central Nervous System, 2nd ed, pg 399). Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the pineal body is
A midline, cone like structure located in the dorso-caudal roof of the 3rd ventricle, attached by peduncles to the habenular and posterior commissures. The stalk contains nerve fibers, blood vessels, connective tissue and parenchymal cells (Paxinos, The Rat Central Nervous System, 2nd ed, pg 399). The atlas records it as a gland at the organ scale in the dog.
Where the pineal body is
It sits within the nervous and endocrine systems. 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 pineal body connects to
The atlas records 7 typed relationships for it, across 4 kinds of connection. part of diencephalon and epithalamus.
Supply and innervation
Arterial supply: superior cerebellar artery.
Also called

Questions
Where is the pineal body?
It sits within the nervous and endocrine systems. 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 pineal body connect to?
Part of: diencephalon and epithalamus.
Is the pineal body 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.
