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
Whether in reference to the anatomy of the human or other members of the Bilateria, the median plane, also called a mid-sagittal plane and related terms, is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side. The term parasagittal plane ...
The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes ) are parallel to it.

The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The crista galli (Latin: "crest of the rooster") is a wedge-shaped, vertical, midline upward continuation of the perpendicular plate of the ethmoid bone of the skull, [1] projecting above the cribriform plate [2] into the cranial cavity. It serves as an attachment for the membranes surrounding the brain. [1]
The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria . Structure
