'axial' is a correct and usable word in written English.
It can be used as an adjective to describe something that is related to, or located along, an axis. It can also refer to the central or main part of something. Example: The car's steering wheel is part of its axial structure, allowing the driver to turn the vehicle. In this sentence, 'axial' is used to describe the structure of the car and its relationship to the axis (axis of rotation) of the steering wheel.
Exposure to daylight helps the retina to release a chemical that slows down an increase in the eye's axial length, which is what most often causes myopia.
Palladio's elevations have always a central emphasis that reflects the axial symmetry of the plan.
He attached great importance to the courts that flanked or stood in front of the house, since they extended its axial symmetry and proportion.
Images produced by ultrasound are not as precise as images obtained through computerized axial tomography (CAT) or magnetic resonance imaging (MRI).
The lower, medioventral part of the somite, called the sclerotome, breaks up into mesenchyme, which contributes to the axial skeleton of the embryo that is, the vertebral column, ribs, and much of the skull.
The tangential velocity of the blade near the hub is much smaller than at the blade tip, while the axial through-flow velocity is maintained nearly constant.
By contrast, in a reaction stage, the effect of the changing pressure exerts a net force in the tangential direction (thus turning the wheel) and also in the axial direction.
In large turbines the axial load can be reduced by admitting the steam flow in the middle and expanding in both axial directions.
Of the three amphibian orders, only caecilians have an axial musculature in which all the hypaxial components, excluding the subvertebral musculature, form an outer muscular sheath.
Although ciliar and flagellar locomotion are clearly forms of appendicular locomotion, pseudopodial locomotion can be classed as either axial or appendicular, depending upon the definition of the pseudopodium.
The relaxation effect is attributed to an isomerization (change in structure) between two forms of the molecule called the axial and equatorial chair forms, as shown below: In the axial form the methyl group (−CH3) lies perpendicular to the principal axis of the carbon ring, whereas in the equatorial form the methyl group lies in the plane of the ring.
