Superior toward the head end or upper part of a structure or the body; above Inferior away from the head end or toward the lower part of a structure or the body; below Ventral (anterior) toward or at the front of the body; in front of Dorsal (posterior) Toward or at the back of the body; behind Medial toward or at the midline of the body; on the inner side of Lateral away from the midline of the body; on the outer side of Intermediate between a more medial and a more lateral structure Proximal closer to the origin of the body part or the point of attachment of a limb to the body trunk Distal farther from the origin of a body part or the point of attachment of a limb to the body trunk Superficial toward or at the body surface Deep (internal) away from the body surface; more internal Anatomical Position erect, feet forward, arms at side with palms facing forward, head facing forward, internationally know Directional Terms allow us to explain where one body structure is in relation to another Regional Terms used to designate specific areas within major body divisions Anterior/Ventral Body Posterior/Dorsal Body Sagittal a vertical plane that divides the body into right and left parts Median Plane (midsagittal plane) sagittal plane that lies exactly in the midline Frontal Planes (Coronal Plane) like sagittal plane lie vertically, divide body into anterior and posterior parts Transverse/Cross-sectionl Plane runs horizontally from right to left, dividing the body into superior and inferior parts. (Transverse is perpendicular to long axis of an organ, horizontal is from front to back) Dorsal Body Cavity protects the fragile nervous system organs, has 2 subdivisions
