A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. 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.
Anatomical planes in a human. Anatomical terms describe structures with relation to four main anatomical planes: [2] The median plane, also called the midsagittal plane, which divides the body into left and right. [2] [11] This passes through the head, spinal cord, navel and, in many animals, the tail. [11]
Terms also help ensure that structures are described consistently, depending on their structure or function. Terms are often derived from Latin and Greek , and like other areas of anatomy are generally standardised based on internationally accepted lexicons such as Terminologia Anatomica .
The alternate spelling Frankfort plane is also widely used, and found in several medical dictionaries, although Frankfurt is the modern standard spelling of the city it is named for. Another name for the plane is the auriculo-orbital plane. Note that in the normal subject, both orbitales and both porions lie in a single plane.
The frontal plane is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. The frontal plane is often referred to as a coronal plane, following Latin corona, which means "crown". [1] The transverse plane is the plane that divides the body or organ horizontally into upper and lower portions ...
The description of the coronal plane applies to most animals as well as humans even though humans walk upright and the various planes are usually shown in the vertical orientation. [citation needed] The sternal plane (planum sternale) is a coronal plane which transects the front of the sternum. [1]
The transverse plane (also known as the horizontal plane, axial plane and transaxial plane) is an anatomical plane that divides the body into superior and inferior sections. [1] It is perpendicular to the coronal and sagittal planes.
Motion, the process of movement, is described using specific anatomical terms.Motion includes movement of organs, joints, limbs, and specific sections of the body.The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved.
