Definition
- Noun:
- A mathematical curve: A sinusoid is the graph of the sine function, typically represented by the equation y = sin x. It is a smooth, periodic wave that oscillates between -1 and 1.
- A small blood vessel: In anatomy, a sinusoid is a tiny, irregularly shaped blood vessel with a lining of endothelial cells, found in certain organs like the liver, spleen, and bone marrow.
