sagittal plane

n.
A longitudinal plane that divides the body of a bilaterally symmetrical animal into right and left sections.

sagittal plane

the anteroposterior plane, or the section parallel to the median plane of the body. Compare frontal plane, median plane, transverse plane.

sag·it·tal plane

(saj'i-tăl plān) [TA]
Originally (and strictly speaking) the sagittal plane is the median plane, and any other plane parallel to it is a parasagittal plane; in contemporary usage and in a broad sense, used for any plane parallel to the median, i.e., as a synonym for parasagittal.

sagittal plane

The front-to-back longitudinal vertical plane that divides the upright body into right and left halves.

cardinal planes of the body

frontal (coronal), sagittal (median) and horizontal (transverse) planes of the body, each of which is oriented on the three planes of space
  • coronal/frontal plane plane equally dividing anterior and posterior aspects; it lies at right angles to sagittal and horizontal planes

  • horizontal/transverse plane plane parallel to the ground or horizontal surface; equally dividing superior and inferior areas; it lies at right angles to both sagittal and frontal planes

  • sagittal/median plane plane equally dividing left and right sides; it lies at right angles to both transverse and frontal planes

sagittal plane,

Plane parallel to median plane; i.e., vertical planes in the anatomic position.

plane

1. a flat surface determined by the position of three points in space.
2. a specified level, as the plane of anesthesia.
3. to rub away or abrade. See also planing and plastic surgery.
4. a superficial incision in the wall of a cavity or between tissue layers, especially in plastic surgery, made so that the precise point of entry into the cavity or between the layers can be determined.

coronal plane
frontal plane, an ambiguous term when applied to quadrupeds and bipeds.
dorsal plane
any plane passing longitudinally through the body from side to side, at right angles to the median plane and dividing the body into dorsal and ventral parts. Called also coronal plane, frontal plane.
horizontal plane
one passing through the body at right angles to the median plane, and dividing the body into upper and lower parts.
inclined plane
an intraoral acrylic or metal appliance used in orthodontics to guide a tooth into a new position by using pressure applied when the mouth is closed normally. Commonest use is to move canines laterally.
median plane
one passing longitudinally through the body from front to back and dividing it into right and left halves.
nasal plane
the space between the nostrils.
nasolabial plane
the extension of the nasal plane between the nostrils into the upper lip in cattle.
nuchal plane
the flat surface at the back of the occipital bone below the nuchal crest.
rostral plane
the bare area on the dorsum of the snout of the pig.
sagittal plane
a vertical plane through the body parallel to the median plane (or to the sagittal suture) and dividing the body into left and right portions.
transverse plane
one passing through the body, at right angles to the sagittal and dorsal planes, and dividing the body into cranial and caudal portions.
vertical plane
one perpendicular to a horizontal plane, dividing the body into left and right, or front and back portions.
