sinus
In medicine, a sinus refers to a cavity or hollow space within a body organ or tissue, often filled with air or fluid, such as the sinuses in the skull connecting to the nasal cavity. In mathematics, sinus or sine is a trigonometric function of an angle that represents the ratio of the length of the side that is opposite the angle to the length of the hypotenuse in a right-angled triangle. In anatomy, a sinus could also refer to a sac or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue, typically ones caused by disease or injury.
