There room three straightforward reference planes used in anatomy: the sagittal plane, the coronal plane, and also the transverse plane.
You are watching: How many midsagittal planes can divide the body
Key PointsA coronal or frontal aircraft divides the body into dorsal and also ventral (back and front, or posterior and also anterior) portions. A transverse plane, likewise known together an axial plane or cross-section, divides the body into cranial and also caudal (head and tail) portions. A sagittal airplane divides the body right into sinister and also dexter (left and right) portions. Body planes have several uses within the anatomy field, consisting of in gaianation.netical imaging, explanation of body motion, and also embryology.
Key Termscoronal plane: any kind of vertical airplane that divides the body right into anterior and posterior (belly and back) sections. transverse plane: Any aircraft that divides the body into superior and also inferior parts, around perpendicular come the spine. sagittal plane: any type of imaginary airplane parallel to the typical plane.
What are Body Planes?
Body plane are theoretical geometric planes offered to divide the body into sections. Castle are frequently used in both human and also zoological anatomy to describe the ar or direction the bodily structures. Reference planes room the conventional planes supplied in anatomical terminology and also include:The sagittal aircraft (lateral or Y-Z plane) divides the body into sinister and also dexter (left and also right) sides. The midsagittal (gaianation.netian) airplane is in the midline through the center of the body, and also all other sagittal planes space parallel to it. The coronal plane (frontal or Y-X plane) divides the body right into dorsal and ventral (back and also front) portions. It also separates the anterior and also posterior portions. The transverse airplane (axial or X-Z plane) divides the body right into superior and inferior (head and also tail) portions. The is generally a horizontal aircraft through the facility of the body and is parallel to the ground.
While these are the significant reference plane of the body, other planes are commonly used in relationship to these three. A longitudinal plane is any airplane perpendicular come the transverse plane, if parasaggital planes space parallel to the saggital plane.The coronal plane, the sagittal plane, and also the parasaggital plane are instances of longitudinalplanes.
Anatomical plane in a Human: There space three straightforward planes in zoological anatomy: sagittal, coronal, and transverse. A human being in the anatomical position, deserve to be described using a coordinate system with the Z-axis going native front come back, the X-axis going from left come right, and also the Y-axis going from as much as down.
Applications of body Planes
gaianation.netical imaging approaches such as sonography, CT scans, MRI scans, or pets scans are among the primary applications of human body planes. Through imaging a patient in standard anatomical position, a radiologist can develop an X-Y-Z axis roughly the patience to apply body planes to the images. The planes have the right to then be provided to identify and also locate the location of the patient’s interior organs. Separation, personal, instance organs can also be split by airplane to aid identify smaller structures within the organ.
Body planes are offered to define anatomical activity in the X-Y-Z coordinate system that the human body moves through. An anatomist might model a limb’s selection of motion by measuring i m sorry planes the limb can move through and how much it is able to travel.

Anatomical adjust during embryological development is additionally described and measured through body planes. For example, throughout human embryonic development the coronal airplane is horizontal, yet becomes vertical as the embryo develops into a fetus. In compare embryology, body planes carry out a basis for comparing the ways in which different species of organisms build anatomically in ~ the womb.
