A straight line, real or imaginary, passing through a body, on which it revolves, or may be supposed to revolve; a line passing through a body or system around which the parts are symmetrically arranged.

A straight line with respect to which the different parts of a magnitude are symmetrically arranged; as, the axis of a cylinder, i. e., the axis of a cone, that is, the straight line joining the vertex and the center of the base; the axis of a circle, any straight line passing through the center.

The stem; the central part, or longitudinal support, on which organs or parts are arranged; the central line of any body.

One of several imaginary lines, assumed in describing the position of the planes by which a crystal is bounded.

another word for stem.

the main stem or central part about which plant organs or plant parts such as branches are arranged

The central shoot of a compound leaf, cone, inflorescence, root, etc.

The second vertebra of the neck, or vertebra dentata.

Also used of the body only of the vertebra, which is prolonged anteriorly within the foramen of the first vertebra or atlas, so as to form the odontoid process or peg which serves as a pivot for the atlas and head to turn upon.

the 2nd cervical vertebra; serves as a pivot for turning the head

An asteroid base established in U.C. 0072 by the Principality of Zeon and the lunar manufacturing cartel. Located in the asteroid belt that lies between Mars and Jupiter, this facility is originally used for resource mining, and during the One Year War it also serves as a way-station for the vessels of the Jupiter Fleet. After the end of the One Year War, Axis becomes a place of refuge for renegade Principality soldiers fleeing the Earth sphere. Half the remaining Principality fleet eventually makes its way to Axis, along with ten thousand soldiers and twenty thousand family members and dependents. These renegades spend years struggling to create a livable home in the far reaches of the asteroid belt, all the while planning for their eventual return. On February 6, U.C. 0086, the exiles finally begin their journey home. Axis, now fitted with a set of thermonuclear pulse thrusters, leaves the asteroid belt and sets off on a twenty-month voyage back to the Earth sphere, where it will dramatically change the balance of power in the Gryps Conflict...

A group of countries originally including Nazi Germany, Italy and Japan, when they signed a pact in Berlin on September 27, 1940. Eventually Bulgaria, Croatia, Hungary and Slovakia joined as well.

in World War II the alliance of Germany and Italy in 1936 which later included Japan and other nations; "the Axis opposed the Allies in World War II"

In 1936, Germany and Italy allied to form the Axis, which was joined by Japan and other opponents of the Allies during World War II.

whenever a pen spins, the axis is the point in the pen which is not moving. Most tricks have only one axis, but some may have two or more.

a critical part of the body's stress response system," explained Bryon H

A direction, usually expressed in degrees, that defines the operating area of a particular audio device such as a speaker or microphone. The area directly in front of the device would be considered (zero)0 degrees or on axis.

The point horizontally and vertically centered in front of a microphone or speaker. Certain microphones have different frequency response curves at different points off-axis. A speaker's directivity is measured off axis. Microphones and speakers typically behave differently off axis than they do on axis.

An arbitrarily chosen point used in the definition of angular momentum. Any object whose direction changes relative to the axis is considered to have angular momentum. No matter what axis is chosen, the angular momentum of a closed system is conserved.

a main, open path that gives a sense of direction, draws one in, and helps to accent a focal point

In correcting for astigmatism, the cylinder power determines how much correction and the axis determines where the correction goes.

The orientation of an astigmatic correction

A direction in a quartz stone. The plural of "axis" is "axes."

a major component of the body's response to stress and refers to the hypothalamus, pituitary, and adrenal glands

see x-axis and y-axis.  The plural of “axis” is “axes”.

(HP/HPA): A direct connection between two or more points. The HP axis is a direct connection between the hypothalamus and the pituitary. The HPA axis is a direct connection between the hypothalamus, the pituitary and the adrenal glands. The plural of axis is axes for two and axii for three or more.

a direction between the sides

One of the three directions of a sheet. Items that you choose for a query appear in the axes. See: top axis, side axis, page axis, axis item.

Axis stands for "Apache eXtensible Interaction System". Axis is essentially Apache SOAP 3.0.

A framework from Apache for constructing SOAP clients and servers.

An implementation of SOAP by the Apache Software Foundation.

One of three vectors (X, Y, and Z) that define the three dimensions of a scene. See also local space, object space, origin axis, world space.

a collection of members from one or more dimensions, which is used to locate or filter specific values in a cube

Synonym for dimension.

A principal direction along which the relative movements of a tool or work piece occur. Three linear axes, occurring at 90 degree angles from each other, named X, Y and Z.

the linear map trace of the axial plane of a fold.

Directions that tools are sent with any engraving machine to create an image. Generally, the X axis is the tool's movement from left to right from the origin point; the Y axis is movement towards and away from the origin; and the Z axis is the tool's up-and-down (perpendicular) movement into and out of the engraving substrate's surface.
