optic tract in dogs
Diencephalic white matter (tract) which is comprised of retinal ganglion cell axons after which they have passed through the optic chiasm[ZFA]. Predominantly white matter structure found in diencephalon consisting of fibers originating in the retina. The optic tract is considered to extend from the point of the optic chiasm and terminates largely, although not exclusively, in the lateral geniculate complex. Other fibers end in the superior colliculus and other structures in the diencephalon, midbrain and brainstem (MM)[NIF]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the optic tract is
Diencephalic white matter (tract) which is comprised of retinal ganglion cell axons after which they have passed through the optic chiasm[ZFA]. Predominantly white matter structure found in diencephalon consisting of fibers originating in the retina. The optic tract is considered to extend from the point of the optic chiasm and terminates largely, although not exclusively, in the lateral geniculate complex. Other fibers end in the superior colliculus and other structures in the diencephalon, midbrain and brainstem (MM)[NIF]. The atlas records it as a nerve at the organ scale in the dog.
Where the optic tract is
It sits within the nervous and sensory 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 optic tract connects to
The atlas records 8 typed relationships for it, across 4 kinds of connection. part of brain, diencephalic white matter and diencephalon, and 2 more.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the optic tract. 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 optic lemniscus, optic tracts, tractus optici, tractus opticus and visual pathway. Searching any of those names reaches this page.

Questions
Where is the optic tract?
It sits within the nervous and sensory 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 optic tract connect to?
Part of: brain, diencephalic white matter, diencephalon, visual system and white matter.
Is the optic tract 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.
