The most common treatment headgear is used for is to correct anteroposterior discrepancies.

By drawing a line connecting these two points, we define the anteroposterior axis (sometimes written antero-posterior).

This movement increases the anteroposterior diameter of the thoracic cavity, and hence aids breathing further.

The opposite end then becomes the posterior end, and by connecting them, an anteroposterior axis is formed.

The anteroposterior diameter of their chest may increase; this sign is sometimes referred as "barrel chest."

The anteroposterior axis is preferred usage for describing the axis connecting the front and the back in humans.

There is some anteroposterior displacement of these two units along the vertebral column, suggesting that they are not ossified to one another.

"Chaussier's line": Anteroposterior raphe of the corpus callosum.

The anteroposterior regionalization of the neural tube in ascidians is comparable to that in vertebrates.

They studied anteroposterior pelvic x-rays and drew horizontal lines through the lower rim of a feature called "teardrop".

Two parallel rows of domed scutes ran down the top of the neck, along the anteroposterior axis (front to back).

The different axes include the anteroposterior axis, dorsoventral axis, and right-left axis.

It is surrounded by inner involuntary and outer voluntary sphincters which keep the lumen closed in the form of an anteroposterior slit.

In higher animals including humans, retinoic acid regulates differential expression of Hox genes along the anteroposterior axis.

The tip of a correctly positioned tracheal tube will be in the mid-trachea, between the collarbones on an anteroposterior chest radiograph.

The anteroposterior axis is divided into three parts: the anterior prosome, the intermediate mesosome, and the posterior metasome.

This is located in the midline of the posterior third of the embryonic region and defines the future anteroposterior axis of the fetus.

Should convergent extension be interrupted or incomplete, the resulting organism will have a short anteroposterior axis, wide notochord, and broad, open neural tube.

The hindbrain, for example, is patterned by Hox genes, which are expressed in overlapping domains along the anteroposterior axis under the control of retinoic acid.

As well as defining the anteroposterior axis, the terms "anterior" and "posterior" also define relative positions along the axis.

The Young classification system is based on mechanism of injury: lateral compression, anteroposterior compression, vertical shear, or a combination of forces.

On its dorsal side, the shaft is flat and wide, while the anteroposterior side is less pronounced; usually resulting in a oval-triangular cross-secion.

Neurons that form the facial nucleus are produced in r4, but move along the anteroposterior axis of the hindbrain into r6, after which they move dorsolaterally.

This anteroposterior line at the inlet is 2 cm less than the diagonal conjugate (distance from undersurface of pubic arch to sacral promontory).
