Sagittal plane

Variations in terminology

• The terms median plane or mid-sagittal plane are sometimes used to describe the running through the midline. This plane cuts the body into halves, 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.
• The term parasagittal is used to describe any plane parallel or adjacent to a given sagittal plane. Specific named parasagittal planes include:
• * The midclavicular line crosses through the clavicle.
• * Lateral sternal and parasternal planes.

• Sagittal axis or anterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes
• Coronal axis, medial-lateral axis, or frontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the transversal planes.
• Extension and flexion are the movements of limbs within the sagittal plane.
• Abduction and adduction'' are terms for movements of limbs within the coronal plane.
