8. Using directional terms, we can explain where one body part/structure is compared to another. For instance, the ears are lateral to the nose. Regional terms help us divide the body into two, the axial and appendicular parts, and are used to designate specific areas within these divisions. The axial part includes the head, neck, and trunk. The appendicular part consists of the limbs which are attached to the body's axis. The body can be cut into different planes such as sagittal, frontal, and transverse planes, which are at right angles from one another. A sagittal plane is vertical and separates the body into right and left parts. The median or midsagittal plane is a sagittal plane that lies exactly in the midline. Parasagittal planes are offset or near the midline also. Frontal planes, also called coronal planes, are vertical planes that divide the body into anterior and posterior parts. Transverse, or horizontal, planes run horizontally from right to left. They separate the body into superior and inferior parts. A transverse section is also called a cross section. Oblique sections are cuts made diagonally between the horizontal and vertical planes.
