In comparative embryology, body planes provide a basis for comparing the ways in which different types of organisms develop anatomically within the womb. For example, during human embryonic development the coronal plane is horizontal, but becomes vertical as the embryo develops into a fetus. 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.Īnatomical change during embryological development is also described and measured with body planes. Individual organs can also be divided by planes to help identify smaller structures within that organ.īody planes are used to describe anatomical motion in the X-Y-Z coordinate system that the body moves through. The planes can then be used to identify and locate the positions of the patient’s internal organs. 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. Medical imaging techniques such as sonography, CT scans, MRI scans, or PET scans are one of the primary applications of body planes. 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. The coronal plane, the sagittal plane, and the parasaggital planes are examples of longitudinalĪnatomical Planes in a Human: There are three basic planes in zoological anatomy: sagittal, coronal, and transverse. A longitudinal plane is any plane perpendicular to the transverse plane, while parasaggital planes are parallel to the saggital plane.

While these are the major reference planes of the body, other planes are commonly used in relation to these three. It is typically a horizontal plane through the center of the body and is parallel to the ground. The transverse plane (axial or X-Z plane) divides the body into superior and inferior (head and tail) portions.It also separates the anterior and posterior portions. connects the tibia to the fibula the lateral collateral ligaments (3). The coronal plane (frontal or Y-X plane) divides the body into dorsal and ventral (back and front) portions. The true ankle joint is responsible for the up-and-down motion of the foot.A neuron has three main parts: dendrites, an axon, and a cell body or soma.

The midsagittal (median) plane is in the midline through the center of the body, and all other sagittal planes are parallel to it. follow these steps Click Sign up to get your first months free Log in with. Neurons (also called neurones or nerve cells) are the fundamental units of. The sagittal plane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides.

Reference planes are the standard planes used in anatomical terminology and include: They are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures. There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.īody planes are hypothetical geometric planes used to divide the body into sections.
