| 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) |

| section | 1. The act of cutting, or separation by cutting; as, the section of bodies. 2. A part separated from something; a division; a portion; a slice. Specifically: A distinct part or portion of a book or writing; a subdivision of a chapter; the division of a law or other writing; a paragraph; an article; hence, the character, often used to denote such a division. "It is hardly possible to give a distinct view of his several arguments in distinct sections." (Locke) A distinct part of a country or people, community, class, or the like; a part of a territory separated by geographical lines, or of a people considered as distinct. "The extreme section of one class consists of bigoted dotards, the extreme section of the other consists of shallow and reckless empirics." (Macaulay) One of the portions, of one square mile each, into which the public lands of the United States are divided; one thirty-sixth part of a township. These sections are subdivided into quarter sections for sale under the homestead and preemption laws. 3. <geometry> The figure made up of all the points common to a superficies and a solid which meet, or to two superficies which meet, or to two lines which meet. In the first case the section is a superficies, in the second a line, and in the third a point. 4. A division of a genus; a group of species separated by some distinction from others of the same genus; often indicated by the sign . 5. A part of a musical period, composed of one or more phrases. See Phrase. 6. The description or representation of anything as it would appear if cut through by any intersecting plane; depiction of what is beyond a plane passing through, or supposed to pass through, an object, as a building, a machine, a succession of strata; profile. In mechanical drawing, as in these Illustrations of a cannon, a longitudinal section (a) usually represents the object as cut through its center lengthwise and vertically; a cross or transverse section (b), as cut crosswise and vertically; and a horizontal section (c), as cut through its center horizontally. Oblique sections are made at various angles. In architecture, a vertical section is a drawing showing the interior, the thickness of the walls, ets, as if made on a vertical plane passed through a building. <mathematics> Angular sections, an instrument to aid in drawing a series of equidistant parallel lines, used in representing sections. Thin sections, a section or slice, as of mineral, animal, or vegetable substance, thin enough to be transparent, and used for study under the microscope. Synonym: Part, portion, division. Section, Part. The English more commonly apply the word section to a part or portion of a body of men; as, a section of the clergy, a small section of the Whigs, etc. In the United States this use is less common, but another use, unknown or but little known in England, is very frequent, as in the phrases "the eastern section of our country," etc, the same sense being also given to the adjective sectional as, sectional feelings, interests, etc. Origin: L. Sectio, fr. Secare, sectum, to cut; akin to E. Saw a cutting instrument: cf. F. Section. See Saw, and cf. Scion, Dissect, Insect, Secant, Segment. Source: Websters Dictionary (01 Mar 1998) |
| section, cross | A transverse cut through a structure. The opposite is a longitudinal section. (12 Dec 1998) |
| section, longitudinal | A cut along the long axis of a structure. (12 Dec 1998) |
| serial section | One of a number of consecutive microscopic section's. (05 Mar 2000) |
| detached cranial section | Craniotomy with section of cranium separated from its soft tissue attachments. Synonym: detached cranial section. (05 Mar 2000) |
| diagonal section | A diagonal cross section attained by slicing, actually or through imaging techniques, the body or any part of the body or anatomic structure, in any plane which does not parallel the longitudinal axis or intersect it at a right angle, i.e., which is neither longitudinal (vertical) nor transverse (horizontal). Synonym: diagonal section. (05 Mar 2000) |
| oblique section | A diagonal cross section attained by slicing, actually or through imaging techniques, the body or any part of the body or anatomic structure, in any plane which does not parallel the longitudinal axis or intersect it at a right angle, i.e., which is neither longitudinal (vertical) nor transverse (horizontal). Synonym: diagonal section. (05 Mar 2000) |
| thin section | A section of tissue for electron microscopic examination; the specimen is fixed, typically in glutaraldehyde and/or in osmium tetroxide, embedded in a plastic resin, and sectioned at less than 0.1 um in thickness with a glass or diamond knife in an ultramicrotome. (05 Mar 2000) |
| transverse section | A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane which intersects the longitudinal axis at a right angle. Since actual sectioning in the transverse plane results in an inferior and a superior portion, an anatomical transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections demonstrate the former unless otherwise stated. Synonym: axial section. (05 Mar 2000) |
| Latzko's cesarean section | A cesarean section in which the uterus is entered by paravesical blunt dissection without entering the peritoneal cavity. (05 Mar 2000) |
| frontal section | A cross section attained by slicing, actually or through imaging techniques, the body or any part of the body or any anatomic structure in the coronal or frontal plane, i.e., in a vertical plane perpendicular to the median or sagittal plane. Since actual sectioning in the coronal plane results in an anterior and a posterior portion, an anatomical coronal section may be a two-dimensional view of the cut surface of the posterior aspect of the anterior portion, or of the anterior aspect of the posterior portion. Synonym: frontal section. (05 Mar 2000) |
| frozen section | <technique> Part of biopsy material frozen immediately to enable pathological analysis in a few minutes on a microscope slide. (16 Dec 1997) |
| longitudinal section | A section that is cut along the long axis of a structure. The opposite is a cross-section. (12 Dec 1998) |
| acute lower GI haemorrhage | <gastroenterology> Typical presentation: Sudden onset of brisk rectal bleeding without blood in gastric aspirate Diagnostic considerations: diverticulosis, angiodysplasia, ischemic colitis, inflammatory bowel disease (rarely), polyps are usually present, carcinoma causing a chronic bleed, haemorrhoids.
