The transverse plane is perpendicular to the longitudinal axis.
longitudinal axis: An axis along the lengthwise direction of the figure or body, usually passing through its center of gravity.
It's longitudinal axis
Rotation
In a beam or length of material, we generally consider the longitudinal axis as the major axis for bending. But torsion will bend the material from the vertical, will twist it around that longitudinal axis. And lateral forces will bend the material across it axis of latitude.
Rotation is the movement around a longitudinal axis.
rotation!

The longitudinal axis of an airplane is an imaginary line running lengthwise from nose to tail. Movement around the longitudinal axis is referred to as "roll" and is controlled by the ailerons. Movement about the longitudinal axis results in a banked attitude of the aircraft (where one wing is higher than the other) and, combined with rudder input causes the aircraft to turn.
The axis is the medical term meaning the longitudinal or long portion of a structure. The Axis of the uterus points up and down (cephalocaudally).
Longitudinal feed is parallel to the axis of rotation of the spindle. Cross feed is perpendicular.
