The sagittal plane (mid-sagittal), or away from the midline and divide it into unequal parts (para-sagittal).
The term sagittal was coined by Gerard of Cremona.[2]
Variations in terminology
Examples of sagittal planes include:
- The terms human abdomen.[4]
- The term parasagittal is used to describe any plane parallel or adjacent to a given sagittal plane.[5] Specific named parasagittal planes include:
The term sagittal derives from the
lambdoidal suture —similar to feathers on an arrow. The Oxford English Dictionary indicates that sagittal in the sense of the sagittal suture along the vertex of the skull pre-dates other anatomical usage.[7]
- 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.[8]
- flexion are the movements of limbs within the sagittal plane.[9]
- adduction are terms for movements of limbs within the coronal plane.[10]
- Sagittal plane movements include flexion, extension, and hyperextension, as well as dorsiflexion and plantar flexion.[11]
