| section, caesarian | Procedure in which an infant, rather than being born vaginally, is surgically removed from the uterus. As the name caesarian suggests, this is not a new procedure. It was done in ancient civilizations upon the death of a pregnant woman near term to salvage the baby. Julius caesar (or, more likely, one of his predecessors) was born by this procedure. The term section in surgery refers to the division of tissue. What is being divided here is the abdominal wall of the mother and the wall of the uterus in order to extract the baby. In shakespeare's macbeth the witches' prophecy was that..none of woman born/ shall harm macbeth (iv.i). Unfortunately for macbeth, the scottish nobleman macduff was from his mother's womb/ untimely ripped. And thus not naturally born of woman (v.vii). Macduff is the only agent capable of destroying macbeth. He kills macbeth in battle. (12 Dec 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) |
| section, lower segment cesarian | A Cesarian section in which the surgical incision (cut) is made in the lower segment of the uterus. (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) |
| lower segment cesarian section | A Cesarian section in which the surgical incision (cut) is made in the lower segment of the uterus. (12 Dec 1998) |
