| Environmental Scanning Electron Microscopy | <technique> Scanning electron microscopy is performed by scanning a focused probe across the surface of the sample to be studied. In the environmental scanning electron microscopy the composition and pressure of the atmosphere around the specimen may be controlled. In favourable cases non-conductive specimens may be examined without coating, and hydrated specimens may be examined with the water still in place. Acronym: ESEM (05 Aug 1998) |

| linker scanning | A type of deletion mutagenesis where the distance and/or reading frame between potentially important regions is maintained by replacement with a synthetic oligonucleotide of known sequence. (05 Mar 2000) |
| right sagittal fissure | A sagittal groove on the undersurface of the liver formed by the fossa vesicae felleae anteriorly and the sulcus venae cavae posteriorly. (05 Mar 2000) |
| groove for superior sagittal sinus | The groove in the midline of the inner table of the calvaria lodging the superior sagittal sinus. Synonym: sulcus sinus sagittalis superioris, sagittal groove, sagittal sulcus, superior longitudinal sulcus. (05 Mar 2000) |
| posterior sagittal diameter | Distance from the sacrococcygeal junction to the middle of an imaginary line running between the left and right ischial tuberosities. (05 Mar 2000) |
| sagittal | 1. Of or pertaining to an arrow; resembling an arrow; furnished with an arowlike appendage. 2. <anatomy> Of or pertaining to the sagittal suture; in the region of the sagittal suture; rabdoidal; as, the sagittal furrow, or groove, on the inner surface of the roof of the skull. In the mesial plane; as, a sagittal section of an animal. <anatomy> Sagittal suture, the suture between the two parietal bones in the top of the skull. Synonym: rabdoidal suture, and interparietal suture. Origin: L. Sagitta an arrow: cf. F. Saguttal. Source: Websters Dictionary (01 Mar 1998) |
| sagittal axis | In dentistry, the line in the frontal plane around which the working side condyle rotates during mandibular movement. (05 Mar 2000) |
| sagittal border of parietal bone | The medial border of the parietal bone entering into the sagittal suture. Synonym: margo sagittalis ossis parietalis. (05 Mar 2000) |
| sagittal crest | A prominent ridge along the sagittal suture of the skull, present in some animals as a result of temporal muscle development. (05 Mar 2000) |
| sagittal fontanel | An occasional fontanel-like defect in the sagittal suture in the newborn. Synonym: Gerdy's fontanel. (05 Mar 2000) |
| sagittal groove | The groove in the midline of the inner table of the calvaria lodging the superior sagittal sinus. Synonym: sulcus sinus sagittalis superioris, sagittal groove, sagittal sulcus, superior longitudinal sulcus. (05 Mar 2000) |
| sagittal line | Any line parallel to the midline, indicating a sagittal plane. (05 Mar 2000) |
| sagittal plane | <dentistry> The longitudinal vertical plane that divides the mouth into two halves (left and right.) (08 Jan 1998) |
| sagittal section | A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body, or any anatomic structure in the sagittal plane, i.e., in a vertical plane parallels to the median plane. Since actual sectioning in the sagittal plane results in a right and a left portion, an anatomical sagittal section may be a two-dimensional view of the cut surface on the medial aspect of either portion. Synonym: parasagittal section. (05 Mar 2000) |
| sagittal split mandibular osteotomy | An intraoral surgical procedure for correction of retrognathism, apertognathia, and prognathism; the mandibular rami and posterior body are sectioned in the sagittal plane. (05 Mar 2000) |
