Anatomical Terminology The Language of Anatomy Special terminology is used to prevent misunderstanding Exact terms are used for Position Direction Regions Structures Anatomical Position Standard body position used as an initial reference point Body is erect Feet parallel Arms at the sides Palms facing forward Directional Terms Superior Inferior Ventral Table 1.1 (1 of 3) Directional Terms Dorsal Medial Lateral Proximal Table 1.1 (2 of 3) Directional Terms Distal Superficia l Deep Table 1.1 (3 of 3) Practice The wrist is _____________ to the hand. proximal The breastbone is __________ to the spine. dorsal The brain is _____________ to the spinal cord. superior The thumb is ___________ to the fingers.
