PLANES AND SECTIONS

PLANE

          imaginary flat surfaces that pass through the body parts


MIDLINE

          is an imaginary vertical line that divides the body into equal right and left sides.

SECTION

          is a cut of a body or one of its organ made along one of the planes.


1. SAGITTAL PLANE

                        a. MIDSAGITTAL/ MEDIAN PLANE

                        b. PARASAGITTAL PLANE

2.  CORONAL/ FRONTAL PLANE

3. TRANSVERSE / CROSS SECTIONAL/ HORIZONTAL PLANE

4. OBLIQUE PLANE

1. SAGITTAL PLANE

sagitt= arrow

                       is a vertical plane that divides the body or organ into  right and left sides


           a. MIDSAGITTAL/ MEDIAN PLANE

                                 divides the body or organ into equal right and left sides

           b. PARASAGITTAL PLANE

                     para=near

                                  divides the body or organ into unequal right and left sides.


2. CORONAL/ FRONTAL PLANE

    corona= crown

                      divides the body organ into anterior and posterior portions.


3. TRANSVERSE / CROSS SECTIONAL/ HORIZONTAL PLANE

                   divides the body or organ into superior and inferior portions.



Sagittal, frontal and transverse plane are all right angles to one another.

4. OBLIQUE PLANE

                passes through the body or an organ at an angle between a transverse plane and a sagittal plane

                                    OR

                between  a transverse plane and a frontal plane.
