Any developmental process that results in the creation of defined areas or spaces within an organism to which cells respond and eventually are instructed to differentiate. The establishment, maintenance and elaboration of a pattern along a line or around a point. The establishment, maintenance and elaboration of the anterior/posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism. Any process resulting in the establishment of polarity along the anterior/posterior axis. The regionalization process by which specific areas of cell differentiation are determined along the anterior-posterior axis. The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism. The pattern specification process by which the polarity of a body or organ axis is established and maintained.
