Trying to figure out where/what the cerebral crus is.. can someone point me in the direction of a good image? Can't find it in HY Neuroanatomy or google. Ty

They're basically the midbrain's medullary pyramids.

Thanks. So on a cross-section of the midbrain they'd be bordering the interpeduncular fossa?

Exactly. The peduncles being referred to by the interpeduncular fossa are the cerebral peduncles, which the cerebral cruri help compose (in addition to the substantia nigra, etc.)
