There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.
Learning Objectives
- Place the 3 bones anatomical reference planes
Key Points
- A coronal or frontal aeroplane divides the trunk into dorsal and ventral (back and front, or posterior and anterior) portions.
- A transverse plane, also known as an axial plane or cross-section, divides the body into cranial and caudal (caput and tail) portions.
- A sagittal aeroplane divides the body into sinister and dexter (left and correct) portions.
- Trunk planes have several uses within the anatomy field, including in medical imaging, descriptions of body motion, and embryology.
Key Terms
- coronal plane: Any vertical aeroplane that divides the body into anterior and posterior (belly and back) sections.
- transverse plane: Any plane that divides the body into superior and inferior parts, roughly perpendicular to the spine.
- sagittal plane: Any imaginary plane parallel to the median plane.
What Are Torso Planes?
Body planes are hypothetical geometric planes used to divide the body into sections. They are commonly used in both man and zoological anatomy to describe the location or direction of actual structures. Reference planes are the standard planes used in anatomical terminology and include:
- The sagittal aeroplane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides. The midsagittal (median) plane is in the midline through the center of the body, and all other sagittal planes are parallel to information technology.
- The coronal aeroplane (frontal or Y-X airplane) divides the trunk into dorsal and ventral (back and front) portions. It also separates the anterior and posterior portions.
- The transverse airplane (axial or Ten-Z aeroplane) divides the trunk into superior and junior (head and tail) portions. Information technology is typically a horizontal airplane through the center of the body and is parallel to the ground.
While these are the major reference planes of the trunk, other planes are commonly used in relation to these three. A longitudinal aeroplane is whatsoever airplane perpendicular to the transverse plane, while parasaggital planes are parallel to the saggital aeroplane.
The coronal aeroplane, the sagittal aeroplane, and the parasaggital planes are examples of longitudinal
planes.
Anatomical Planes in a Human being: There are three basic planes in zoological beefcake: sagittal, coronal, and transverse. A human being in the anatomical position, can be described using a coordinate organization with the Z-centrality going from forepart to dorsum, the X-centrality going from left to right, and the Y-axis going from up to downwardly.
Applications of Body Planes
Medical imaging techniques such as sonography, CT scans, MRI scans, or PET scans are i of the primary applications of body planes. By imaging a patient in standard anatomical position, a radiologist can build an X-Y-Z axis around the patient to employ trunk planes to the images. The planes tin so be used to identify and locate the positions of the patient's internal organs. Individual organs can too be divided past planes to help identify smaller structures inside that organ.
Body planes are used to depict anatomical motion in the Ten-Y-Z coordinate arrangement that the body moves through. An anatomist could model a limb'south range of motion past measuring which planes the limb tin can motion through and how far information technology is able to travel.
Anatomical modify during embryological evolution is also described and measured with body planes. For instance, during homo embryonic development the coronal plane is horizontal, but becomes vertical every bit the embryo develops into a fetus. In comparative embryology, body planes provide a footing for comparing the ways in which different types of organisms develop anatomically within the womb.
