2. Transverse (or horizontal) refers to a cut that divides
the body into superior and inferior portions.
3. Coronal (or frontal) refers to a section that divides the
body into anterior and posterior portions.
Sometimes a cylindrical organ such as a blood ves sel
is sectioned. In this case, a cut across the structure is
called a cross section, an angular cut is called an oblique
section, and a lengthwise cut is called a longitudinal
section (fig. 1.20).
