Anteroposterior

We start with fundamental structures; anteroposterior axis, triploblasty, segmentation, etc., and then these structures evolved into more complex and derived structures. ❋ Unknown (2008)

A first model describing the three independent systems involved in establishing the anteroposterior axis was presented in an article in SCIENCE, with Frohnhöfer and Lehmann, in 1987. ❋ Unknown (1996)

A large fraction of the genes identified in both the zygotic and the maternal screens affect either the anteroposterior or the dorsoventral axis. ❋ Unknown (1995)

The refinement of the dorsoventral pattern on the dorsal side involves a long range signalling process, unlike the series of prepatterns of transcription factors observed along the anteroposterior axis (40). ❋ Unknown (1995)

These studies led to the surprising conclusion that the basic features of body organization, such as specification along the anteroposterior axis, and polarity of gastrulation, are apparently conserved in organisms of different animal phyla (21, 22). ❋ Unknown (1995)

The subsequent phenotypic analysis and molecular cloning of many of these genes, and investigation into the interactions of their products, resulted in a rather complete general picture of the mechanisms establishing the anteroposterior and the dorsoventral axis of the early embryo ❋ Unknown (1995)

The identification and analysis of the maternal genes affecting the segmentation pattern revealed that the anteroposterior axis is controlled by three groups of genes, each independently determining a subset of the pattern, the segmented anterior or posterior, or the unsegmented terminal regions of the embryo (35-37). ❋ Unknown (1995)

On this wall are three irregular anteroposterior passages, termed the superior, middle, and inferior meatuses of the nose. ❋ Unknown (1918)

The anteroposterior or conjugate diameter extends from the sacrovertebral angle to the symphysis pubis; its average measurement is about 110 mm. in the female. ❋ Unknown (1918)

One taken laterally, low down on the neck but clear of the shoulder, will often show a bone or other semiopaque object invisible in the anteroposterior exposure. ❋ Chevalier Jackson (1911)

The first step in the solution of the mechanical problem is the study of the roentgenograms made in at least three planes; (1) anteroposterior, (2) lateral, and (3) the plane corresponding to the greatest plane of the foreign body. ❋ Chevalier Jackson (1911)

Lateral, anteroposterior, and sometimes also quartering roentgenograms are necessary. ❋ Chevalier Jackson (1911)

Whenever time permits roentgenograms, lateral and anteroposterior, should be made, the lateral one as low in the neck as possible. ❋ Chevalier Jackson (1911)

The fluoroscope should show both the lateral and anteroposterior planes. ❋ Chevalier Jackson (1911)

The woman had a uniformly contracted pelvis whose anteroposterior diameter was about 1 1/4 inches. ❋ Unknown (1896)

In Figure III. we have a photograph of the skeleton of a Chinese lady's foot about five inches in anteroposterior diameter. ❋ Unknown (1896)

The sacral promontory was exaggerated, and the anteroposterior pelvic diameter of the inlet in consequence diminished. ❋ Unknown (1896)

In Figure III we have a photograph of the skeleton of a Chinese lady's foot about five inches in anteroposterior diameter. ❋ Unknown (1896)
