Anatomical Planes

PLANS ANATOMICS

The) Sectional Plans: Four plans are key:

1) Middle Plan: Vertical plane that passes longitudinally through the body, dividing it into right and left halves. Parasagital, used by neuroanatomists and neurologists is unnecessary because any plane parallel to the median plane is sagittal by definition. A plane close to the median is a Paramedian Plane.

 

 

2) Sagittal Plans: These are vertical planes that pass through the body, parallel to the median plane.

3) Frontal Planes (Coronal): are vertical planes that pass through the body at right angles to the median plane, dividing it into anterior (front) and posterior (rear) parts.

 

4) Transverse Plans (Horizontal): These are planes that pass through the body at right angles to the coronal and median planes. Divide the body into upper and lower parts.

 

 

 

B) Tangential Plans: Suppose now that the anatomically placed individual is in a glass coffin. The six walls that make up the coffin would represent the tangential planes:

 Higher Plan: would be the wall that is above the head

 Lower Plan: is what lies under the feet.

 Previous Plan: is the plane that passes in front of the body.

 Later Plan: is what would form the bottom of the coffin, ie behind the back.

 Side Plans: are the two side walls, which limit the upper and lower limbs on the right and left.
