COMMISSURE, COMMISSURA, a term used by some authors, for the small meatus's or interstices of bodies; or the little clefts between the particles; especially when those particles are broadish and flat, and lie contiguous to one another, like thin plates or lamellæ. See PORE. The word literally signifies a joining, or connecting of one thing to another.
Commissure, in architecture, &c. denotes the joint of two stones; or, the application of the surface of the one to that of the other. See MASONRY.
Among anatomists, commissure is sometimes also used for a future of the cranium, or skull. See SUTURE.
