There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane. Learning Objectives
There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.
What Are Body Planes?
Body planes are hypothetical geometric planes used to divide the body into sections. They are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures. Reference planes are the standard planes used in anatomical terminology and include:
While these are the major reference planes of the body, other planes are commonly used in relation to these three. A
longitudinal plane is any plane perpendicular to the transverse plane, while parasaggital planes are parallel to the saggital plane.
Anatomical Planes in a Human: There are three basic planes in zoological anatomy: sagittal, coronal, and transverse. A human in the anatomical position, can be described using a coordinate system with the Z-axis going from front to back, the X-axis going from left to right, and the Y-axis going from up to down.
Applications of Body Planes
Medical imaging techniques such as sonography, CT scans, MRI scans, or PET scans are one 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 apply body planes to the images. The planes can then be used to identify and locate the positions of the patient’s internal organs. Individual organs can also be divided by planes to help identify smaller structures within that organ.
Body planes are used to describe anatomical motion in the X-Y-Z coordinate system that the body moves through. An anatomist could model a limb’s range of motion by measuring which planes the limb can move through and how far it is able to travel.
Anatomical change during embryological development is also described and measured with body planes. For example, during human embryonic development the coronal plane is horizontal, but becomes vertical as the embryo develops into a fetus. In comparative embryology, body planes provide a basis for comparing the ways in which different types of organisms develop anatomically within the womb.
Which of the following statements correctly describe anatomical position?
Anatomical position, or standard anatomical position, refers to the positioning of the body when it is standing upright and facing forward with each arm hanging on either side of the body, and the palms facing forward. The legs are parallel, with feet flat on the floor and facing forward.
Which of the following descriptions correctly describes anatomical position quizlet?
The body is upright, the legs are close together, the feet are flat on the floor, the arms are close to the sides, and the face and palms of the hands are facing forward.
Which type of section would separate superior and inferior structures?
The transverse plane (axial or X-Z plane) divides the body into superior and inferior (head and tail) portions. It is typically a horizontal plane through the center of the body and is parallel to the ground.
Which plane divides the body into left and right portions?
Sagittal Plane (Lateral Plane) - A vertical plane running from front to back; divides the body or any of its parts into right and left sides.
