arcuate

The left hemisphere, the part of your brain responsible for language comprehension, Wernicke’s area, is connected to the part responsible for speech production, Broca’s area, by a fiber tract called the arcuate fasciculus.

What’s happening is a singer is better able to hear something and produce it vocally, presumably using this right arcuate fasciculus.

The frustules are curved or arcuate (arcus, a bow) in the side view, oblong and narrowed at the ends in the front view.

Valve narrow, with arcuate dorsal and straight ventral margin, acute at the ends.

Valve linear, with dorsal margin arcuate and the ventral margin straight.

Valve arcuate, without cost, transversely striated; pseudoraphe absent; pseudo-nodules at each end.

The valves of the auxospore are usually more or less arcuate, as in Cymbella, to which the genus is closely allied.
