diameter

 [di-am´ĕ-ter]
the length of a straight line passing through the center of a circle and connecting opposite points on its circumference; hence the distance between the two specified opposite points on the periphery of a structure such as the cranium or pelvis.
cranial d's (craniometric d's) imaginary lines connecting points on opposite surfaces of the cranium; the most important are biparietal, that joining the parietal eminences; bitemporal, that joining the extremities of the coronal suture; cervicobregmatic, that joining the center of the anterior fontanel and the junction of the neck with the floor of the mouth; frontomental, that joining the forehead and chin; occipitofrontal, that joining the external occipital protuberance and the most prominent midpoint of the frontal bone; occipitomental, that joining the external occipital protuberance and the most prominent midpoint of the chin; suboccipitobregmatic, that joining the lowest posterior point of the occiput and the center of the anterior fontanel.
pelvic diameter see pelvic diameter.

di·am·e·ter

(dī-am'ĕ-tĕr),
1. A straight line connecting two opposite points on the surface of a more or less spheric or cylindric body, or at the boundary of an opening or foramen, passing through the center of such body or opening.
2. The distance measured along such a line.
[G. diametros, fr. dia, through, + metron, measure]
