| 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) |
| lower uterine segment cesarean section | A cesarean section in which the uterus is entered in its lower segment by a transperitoneal approach. (05 Mar 2000) |
