There space three straightforward reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.

You are watching: The plane that divides the body into front and back is:

Key Points

A coronal or frontal airplane divides the body right into dorsal and also ventral (back and also front, or posterior and anterior) portions. A transverse plane, likewise known as an axial aircraft or cross-section, divides the body into cranial and also caudal (head and tail) portions. A sagittal plane divides the body right into sinister and dexter (left and right) portions. Human body planes have actually several offers within the anatomy field, including in clinical imaging, descriptions of human body motion, and embryology.

Key Terms

coronal plane: any type of vertical airplane that divides the body right into anterior and posterior (belly and back) sections. transverse plane: Any plane that divides the body right into superior and inferior parts, about perpendicular to the spine. sagittal plane: any type of imaginary aircraft parallel come the average plane.

What space Body Planes?

Body planes are hypothetical geometric planes supplied to divide the body into sections. Castle are typically used in both human and also zoological anatomy to describe the ar or direction that bodily structures. Reference planes room the typical planes provided in anatomical terminology and include:

The sagittal airplane (lateral or Y-Z plane) divides the body into sinister and also dexter (left and right) sides. The midsagittal (smashville247.netian) plane is in the midline through the center of the body, and all other sagittal planes are parallel come it. The coronal plane (frontal or Y-X plane) divides the body right into dorsal and ventral (back and front) portions. It additionally separates the anterior and posterior portions. The transverse plane (axial or X-Z plane) divides the body into superior and inferior (head and also tail) portions. It is frequently a horizontal plane through the center of the body and is parallel come the ground.

While these room the significant reference planes of the body, other planes are commonly used in relationship to this three. A longitudinal airplane is any airplane perpendicular to the transverse plane, if parasaggital planes room parallel to the saggital plane.The coronal plane, the sagittal plane, and also the parasaggital planes are examples of longitudinalplanes.


Anatomical plane in a Human: There room three straightforward planes in zoological anatomy: sagittal, coronal, and also transverse. A person in the anatomical position, can be defined using a coordinate device with the Z-axis going from front to back, the X-axis going native left to right, and also the Y-axis going from approximately down.

Applications of body Planes

smashville247.netical imaging techniques such as sonography, CT scans, MRI scans, or pets scans are one of the major applications of human body planes. By imaging a patient in standard anatomical position, a radiologist can develop an X-Y-Z axis approximately the patient to use body planes to the images. The planes can then be used to identify and also locate the positions of the patient’s internal organs. Individual organs can additionally be divided by airplane to aid identify smaller sized structures within the organ.

Body plane are provided to explain anatomical movement in the X-Y-Z coordinate device that the human body moves through. An anatomist might model a limb’s selection of movement by measuring i m sorry planes the limb deserve to move through and how far it is able to travel.

Anatomical readjust during embryological advancement is likewise described and also measured v body planes. Because that example, throughout human embryonic breakthrough the coronal airplane is horizontal, but becomes vertical as the embryo establishes into a fetus. In comparative embryology, human body planes carry out a basis for comparing the methods in i beg your pardon different types of organisms construct anatomically in ~ the womb.
