sagittal section

(redirected from parasagittal section)

section

 [sek´shun]
1. an act of cutting.
2. a cut surface.
3. a segment or subdivision of an organ.
abdominal section laparotomy; incision of the abdominal wall.
cesarean section delivery of a fetus by incision through the abdominal wall and uterus; see also cesarean section.
frontal section a section through the body passing at right angles to the median plane, dividing the body into dorsal and ventral parts.
frozen section a specimen cut by microtome from tissue that has been frozen; see also frozen section.
perineal section external urethrotomy.
sagittal section a section through the body coinciding with the sagittal suture, thus dividing the body into right and left halves.
serial s's histologic sections of a specimen made in consecutive order and so arranged for the purpose of microscopic examination.

sag·it·tal sec·tion

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, that is, in a vertical plane parallel to the median plane. Inasmuch as actual sectioning in the sagittal plane results in right and left portions, an anatomic sagittal section may be a two-dimensional view of the cut surface on the medial aspect of either portion.

sagittal section

an anteroposterior cross section produced by slicing, laterally or through imaging techniques, a body or body part in a vertical plane parallel to the median plane.
