What's the difference between aperture and trigone?
Aperture
Definition:
(n.) The act of opening.
(n.) An opening; an open space; a gap, cleft, or chasm; a passage perforated; a hole; as, an aperture in a wall.

(20) The estimated doses to the third, fourth, fifth, and sixth cranial nerves was calculated at a saggital plane 13 to 15 mm from the pituitary by using computer-drawn dosimetry charts for the respective aperture size.
Trigone
Definition:
(n.) A smooth triangular area on the inner surface of the bladder, limited by the apertures of the ureters and urethra.
Example Sentences:
