sinusoid
Smooth oscillating wave
A sinusoid is a curve with the smooth, wavelike shape of a sine function—rising and falling in regular, repeating oscillations.
The term appears in mathematics, physics, and engineering to describe waveforms: The voltage alternates in a sinusoid.
In anatomy, sinusoids are irregular blood vessels found in the liver, spleen, and bone marrow, named for their winding, curved paths.
