What the cerebral peduncle is

Synonym for macrodissected adult human tegmentum (Vicq d'Azyr, 1784; Swanson, 2000); pp. 555-556. Later used thus by for example His (1893b, p. 178), Herrick (1915, p. 160), Strong & Elwyn (1943, p. 17), Carpenter (1976, p. 367), Williams & Warwick (1980, p. 935). The atlas records it as a nerve at the organ scale in the human body.

Where the cerebral peduncle 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 cerebral peduncle connects to

The atlas records 7 typed relationships for it, across 3 kinds of connection. part of midbrain.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the cerebral peduncle. 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 CP, cerebral peduncle, peduncle of midbrain, pedunculus cerebri, cerebal peduncle and cerebral peduncle (archaic), and 3 more. Searching any of those names reaches this page.

Questions

Where is the cerebral peduncle?

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 cerebral peduncle connect to?

Part of: midbrain.

Is the cerebral peduncle the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
