Upon studying the standard anatomical position, for which it includes the body planes and sections, individuals can clearly understand and analyze the human anatomy and physiology. Several anatomical terminologies can describe the relative placement of different appendages within the standardized position of an individual's anatomy. Such terms include proximal and distal, which define how close or far something is, respectively, as well as posterior and dorsal, which refer to the body's rear. The standard anatomical position establishes distinct points of comparison that reduce ambiguity when using anatomical terminologies.
