Latitude and longitude are two of the most important things map readers and sailors must understand. To determine longitudinal axis one must look at the center of the object and imagine a line coming straight through it.
longitudinal axis: An axis along the lengthwise direction of the figure or body, usually passing through its center of gravity.

Rotation
The axis just defines their rotation. It is relative to spin, so if a body does not spin, it has no axis. Kind of an imaginary line, like the equator. It is used for reference. Also an object that is not round and symmetrical and has a length and a width can also be referenced by these dimensions. The Longitudinal axis is usually an axis through the longest dimension of the body.
Longitudinal Wave
The transverse plane is perpendicular to the longitudinal axis.

No, pronation is not a movement around the longitudinal axis. Pronation refers to the inward rotation of the forearm or foot. Rotation around the longitudinal axis would involve spinning or twisting along the length of the body.
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.

Transverse Fracture
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.
The longitudinal axis of a bone is an imaginary line that runs along the length of the bone from one end to the other. It helps to define the orientation and direction of forces acting on the bone, such as during movement or weight-bearing activities. Understanding the longitudinal axis is important in biomechanics and in the study of bone structure and function.
