That is the sagittal plane
A vertical plane at right angles to a sagittal plane, dividing the body into anterior and posterior portions. Also called frontal plane.
A vertical field running through the body from front to back that divides the body into unequal left and right sides is called the parasagittal plane. This plane runs parallel to the sagittal plane, which divides the body into equal left and right halves. The parasagittal plane can vary in position, creating different asymmetrical divisions of the body.
Sagittal Plane
From a vertical point of view, the plane that divides the body into left and right portions is the lateral plane or sagittal plane. Dividing the body into planes makes studying anatomy less confusing as body parts can be more easily identified.
The body is divided into equal vertical left and right halves by the sagittal plane.
The coronal plane is also known as the frontal plane, which divides the body into front and back sections. It is perpendicular to the sagittal plane and horizontal to the transverse plane.
Transverse or horizontal plane: It is parallel to the ground and this imaginary plane divide body or its part in to superior (upper) or inferior (lower) parts
midsagittal plane
Midline SAGITTAL
This is called a sagittal plane if divided this way with symmetrical left and right halves. If the section produces asymmetrical halves, this is a parasagittal section.
Coronal, sagittal and transverse planes divide the human body into a three-dimensional grid in the study of human anatomy, to describe the location of body parts in relation to each other.The coronal plane is a vertical plane that divides the body into the ventral (belly, front) and dorsal(back) sections. The sagittal plane is a vertical plane that passes through the ventral and dorsal sections to make a 90° angle with the coronal plane, dividing the body into left and right halves.
The plane that passes through the body from front to back, dividing it into right and left sides, is called the sagittal plane. It runs vertically and can be further classified into the midsagittal plane (which divides the body into equal right and left halves) and parasagittal planes (which divide it into unequal parts).
