| plane of inlet | The upper opening of the true pelvis, bounded anteriorly by the pubic symphysis and the pubic crest on either side, laterally by the iliopectineal lines, and posteriorly by the promontory of the sacrum. Synonym: apertura pelvis superior, aditus pelvis, first parallel pelvic plane, pelvic brim, pelvic inlet, pelvic plane of inlet, plane of inlet. (05 Mar 2000) |

| plane of midpelvis | The plane that extends from the end of the sacrum to the inferior border of the pubic symphysis; it is bounded posteriorly by the end of the sacrum, laterally by the ischial spines, and anteriorly by the inferior border of the pubic symphysis. Synonym: midplane, plane of least pelvic dimensions, plane of midpelvis, third parallel pelvic plane. (05 Mar 2000) |
| plane of outlet | The lower opening of the true pelvis, bounded anteriorly by the pubic arch, laterally by the rami of the ischium and the sacrotuberous ligament on either side, and posteriorly by these ligaments and the tip of the coccyx. Synonym: apertura pelvis inferior, apertura pelvis minoris, fourth parallel pelvic plane, pelvic outlet, pelvic plane of outlet, plane of outlet. (05 Mar 2000) |
| plane of regard | An imaginary plane through which the point of regard moves as the eyes are turned from side to side. (05 Mar 2000) |
| plane-parallel | <optics> Having opposite surfaces exactly plane and parallel, as a piece of glass. Source: Websters Dictionary (01 Mar 1998) |
| plane-polarized light | <chemistry> Light which is passed through a filter which blocks out all the light except that which ocillates in one plane. (09 Jan 1998) |
| plane suture | A simple firm apposition of two smooth surfaces of bones, without overlap, as seen in the lacrimomaxillary suture. Synonym: sutura plana, harmonia, harmonic suture. (05 Mar 2000) |

| plane wart | A smooth, flat, flesh-coloured wart of small size, occurring in groups, seen especially on the face of the young; often associated with common warts of the hands, due to human papilloma virus, commonly, types 3 and 10. Synonym: flat wart, plane wart, verruca plana juvenilis. (05 Mar 2000) |
| plane wave | <microscopy> Wave in which wavefronts are parallel to a plane normal to the direction of propagation. (05 Aug 1998) |
| coronal plane | A vertical plane at right angles to a sagittal plane, dividing the body into anterior and posterior portions. Synonym: frontal plane. (05 Mar 2000) |
| cove plane | A classic description of terminal inversion of the electrocardiographic T wave with the initial portion arched above the baseline and the terminal portion below it, the former being rounded and the latter pointed. (05 Mar 2000) |
| popliteal plane of femur | The posterior surface of the lower end of the femur between the diverging lips of the linea aspera. Synonym: facies poplitea femoris, planum popliteum, popliteal plane of femur. (05 Mar 2000) |
| sagittal plane | <dentistry> The longitudinal vertical plane that divides the mouth into two halves (left and right.) (08 Jan 1998) |
| principal plane | <microscopy> A plane normal to the principal axis of a lens, passing through a principal point. In geometrical construction of ray diagrams through a perfect lens, the single plane that can be considered (disregarding the refraction of the rays at each optical interface) to convert paraxial rays into rays converging onto the rear focal point. For thin symmetrical lenses, there is one principal plane that bisects the lens. For thick or complex lenses, there is a principal plane for the paraxial ray to the left, and another for the paraxial ray to the right, of the lens. (05 Aug 1998) |
