2 SECTION vs. PLANE SECTION = a cut PLANE: when the section is made through the body wall or through an organ, it is made along an imaginary surface or line called a plane.
3 SAGITTAL PLANE divides the body into left/righ parts.
4 MIDSAGITTAL (MEDIAN) PLANE divides the body into EQUAL left & right parts PARASAGITTAL PLANE divides the body into UNEQUAL left & right parts
5 CORONAL (FRONTAL) PLANE a longitudinal plane that divides the body (or an organ) into anterior and posterior parts pig kidney
6 TRANSVERSE PLANE divides the body into superior & inferior parts.
7 CROSS SECTIONS When organs are sectioned along the transverse plane, the sections are commonly called cross sections. a cross section of a kiwi fruit!
