{{wiktionary|meatus}}

In anatomy, a meatus {{IPAc-en|m|iː|ˈ|eɪ|t|ə|s}},

>OED 2nd edition, 1989, as {{IPA|/miːˈeɪtəs/}}. plural "meatus" or "meatuses",

>Entry "meatus" in Merriam-Webster Online Dictionary. is a natural body opening or canal.

Meatus may refer to:

  • the external acoustic meatus, the opening of the ear canal
  • The internal auditory meatus, a canal in the temporal bone of the skull
  • the urinary meatus, which is the opening of the urethra, situated on the glans penis in males, and in the vulva in females
  • the superior meatus, middle meatus and inferior meatus of the nose

(The plural forms of "meatus" are: meatus, as a Latin form (of the fourth declension noun class, which the word belongs to); or meatuses, as a normally derived English plural; or often, and incorrectly, meati, by false analogy with the very common Latin -us/-i forms (such as alumnus/alumni), i.e., the second declension noun class.)
