<Li> The terms median plane or mid-sagittal plane are sometimes used to describe the sagittal plane running through the midline . This plane cuts the body into halves (assuming bilateral symmetry), passing through midline structures such as the navel and spine . It is one of the planes which, combined with the Umbilical plane, defines the four quadrants of the human abdomen . </Li> <Li> The term parasagittal is used to describe any plane parallel to the sagittal plane . In practice, such a section is often referred to simply as a "sagittal" view because viewing is achieved along the sagittal axis (see below). Owing to the specific nature of its definition, only one true sagittal plane exists, and it corresponds to the "mid-sagittal" view . Be aware that the term "sagittal view" may be applied to any parasagittal section as well as the sagittal plane, as the parasagittal and sagittal axes are identical (parallel to the sagittal plane). Specific named parasagittal planes include: <Ul> <Li> The midclavicular line crosses through the clavicle . </Li> <Li> Other sagittal lines / planes include the lateral sternal and parasternal . </Li> </Ul> </Li> <Ul> <Li> The midclavicular line crosses through the clavicle . </Li> <Li> Other sagittal lines / planes include the lateral sternal and parasternal . </Li> </Ul> <Li> The midclavicular line crosses through the clavicle . </Li>

Generally a plane divides a body or organ into left and right halves
