1. 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.

Examples of Sinus in a Sentence

1. Kaley Cuoco:

   I was actually really addicted to nose spray like Afrin, like for years. Like at award shows I would have to pick out the right clutch to be able to fit my Afrin in it.And I’d be under the table like...snorting it. I’m surprised there were no photos of what I was snorting Afrin. And I couldn’t get enough and it was such a problem. And I ruined my sinus. So I had to get it fixed.

And doing saltwater gargles if you have a sore throat.
