1. a line through a center of a body, or about which a structure revolves.
the second cervical vertebra. adj., adj ax´ial.
2. the position of the cylindrical part of a lens, used for correcting astigmatism; the range of values is from 0° to 180°.
celiac axis celiac trunk.
dorsoventral axis one passing from the posterior to the anterior surface of the body.
electrical axis of heart the preponderant direction of current flow through the heart, a consequence of the electromotive forces within the heart. It may be computed on either an instantaneous basis or a mean basis.
frontal axis an imaginary line running from right to left through the center of the eyeball.
axis of heart a line passing through the center of the base of the heart to the apex.
instantaneous electrical axis the electrical axis of the heart determined at a given point in time.
lead axis the imaginary direct line between the two electrodes of the bipolar leads or between the positive electrode and the reference point of the unipolar leads.
mean electrical axis the average direction of the activation or repolarization process during the cardiac cycle; it may be determined for any deflection (P, QRS, ST-T) and in the frontal, transverse, or sagittal plane.
optic axis
1. a line connecting the center of the anterior curvature of the cornea (anterior pole) with that of the posterior curvature of the sclera (posterior pole).
2. the hypothetical straight line passing through the centers of curvature of the front and back surfaces of a simple lens.
phlebostatic axis a point located by drawing an imaginary line from the fourth intercostal space at the sternum and finding its intersection with an imaginary line drawn down the center of the chest below the axillae.
Phlebostatic axis.
sagittal axis an imaginary line extending through the anterior and posterior poles of the eye.
visual axis an imaginary line passing from the midpoint of the visual field to the fovea centralis.
Axes of the eye. From Dorland's , 2000.

The celiac axis gives rise to the splenic, left gastric, and common hepatic arteries.
The incidence of celiac axis injury has not been previously reported in the literature.
Penetrating trauma remains the predominant cause of the majority of celiac axis injuries.
Surgical exposure of the celiac axis can be accomplished by medial rotation of the left-sided viscera, including mobilization of the left colon, spleen, pancreas, and stomach.
The surgical treatment of celiac axis injuries consists either of primary repair or ligation.
In the Kashuk et al (7) series, all six patients with celiac axis injuries survived, although no description of their surgical treatment is presented.
However, for the six patients with one associated vascular injury, the mortality rate was lower (33%), and all patients with isolated celiac axis injuries survived.
According to Kavic et al, (10) ligation has not been the preferred approach to deal with celiac axis injury.
