Chapter 1: Body Planes And Sections

Frontal And Parasagittal Planes

Divide the body or organ in two sections with each section containing a piece of the heart and a piece of each lung

Median/Midsagittal Plane

Divides the body or organ exactly in the midline or into EQUAL right and left sections Cut was made perfectly on midline section

Sections

Cuts or sections made along a body plane Named after plane, so a sagittal cut results in a sagittal section

Transverse/Horizontal/Cross Section Plane

Divides body or organ horizontally into superior and inferior sections Produces a "cross section"

Parasagittal Plane

Divides body or organ into UNEQUAL right and left sections Cut was off-centered, not in midline section

Frontal/Coronal Plane

Divides body or organ vertically into anterior and posterior sections

Sagittal Plane

Divides body or organ vertically into right and left parts

Body Planes

Surfaces along which the body or structures may be cut for anatomical study It includes 3 common planes: sagittal plane, frontal (coronal) plane, and transverse (horizontal) plane

Oblique Sections

They are sections that are made diagonally between the horizontal and the vertical planes Result of cuts at angle other than 90 degrees to vertical plane
