parts:

Body Planes
Body Directions
Body Cavities

Imaginary lines used to divide the body into
sections for descriptive purposes. The planes
are in reference to anatomic position
Vertical planes (up and down)

Midsagittal (also known as midline) divides the
body into equal left and right halves
Sagittal plane is a vertical line that divides the
body into unequal left and right portions

divides the body into front (anterior) and back
(posterior) portions.
