| complement pathway, classical | The sequential activation of complement, initiated by antigen-antibody complex and the binding of complement factor c1q to the fc region of the antibody. (12 Dec 1998) |
| epidemiology, classical | The study of populations in order to determine the frequency and distribution of disease and measure risks. (12 Dec 1998) |
| abdominal section | Transabdominal incision into the peritoneal cavity. Synonym: abdominal section, laparotomy, ventrotomy. Origin: celio-+ G. Tome, incision Vaginal celiotomy, opening the peritoneal cavity through the vagina. Synonym: culdotomy. (05 Mar 2000) |
| attached cranial section | Craniotomy with a segment of the calvaria and attached soft tissues turned as a flap to expose the cranial cavity. Synonym: attached cranial section, osteoplastic craniotomy. (05 Mar 2000) |
| axial 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) |
| caesarian section | Procedure in which an infant, rather than being born vaginally, is surgically removed from the uterus. Also referred to as a C section. As the name Caesarian suggests, this is not exactly a new procedure. It was done in ancient civilizations upon the death of a near-full-term pregnant woman to salvage the baby. Julius Caesar (or one of his predecessors) was born by this procedure. Hence, the name Caesarian. The term section in surgery refers to the division of tissue. What is being divided here is the abdominal wall of the mother as well as 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 was the only agent capable of destroying Macbeth. He killed Macbeth in battle. (12 Dec 1998) |
| vaginal birth after cesarian section | It was once the rule that after a c-section, the next delivery also had to be by c-section. Now vaginal delivery after cesarian section (vbac) is frequently feasible. See: vbac. (12 Dec 1998) |
| parasagittal 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) |
| median section | A cross section attained by slicing in the median plane, actually or through imaging techniques, the body or any part of the body which occupies or crosses the median plane or by slicing any generally symmetrical anatomic structure, such as a finger or a cell, in its midline. Since actual sectioning the median plane results in a right and a left half, an anatomical median section may be a two-dimensional view of the cut surface on the medial aspect of either half. Synonym: midsagittal section. (05 Mar 2000) |

| perineal section | Any section through the perineum, either lateral or median lithotomy or external urethrotomy. (05 Mar 2000) |
| permanent section | A technique in which a thin slice of biopsy tissue is mounted on a slide to be examined under a microscope by a pathologist in order to establish a diagnosis. (09 Oct 1997) |
