Uniaxial movement refers to motion that occurs in only one direction or along a single axis. In the context of Biology or anatomy, uniaxial movement can refer to the motion of a joint that allows movement in only one plane or direction, such as flexion and extension at the elbow joint. This is in contrast to biaxial or multiaxial movement, which involve motion in multiple planes or around multiple axes.
an elbow is a u·ni·ax·i·al joint that permits movement around one axis only.
The three planes are coronal, sagittal, and transverse (you probably knew this already) so a multiaxial joint can move in all three. So to answer the question, it would be three.
the pivot and hinge joints. they can only move back and forth in one direction, as apposed the the biaxial joint, condyloid, and saddle which can move back and forth in 2 different directions and the multiaxial joint Ball and socket joint which can move in many directions.
No, the hip is a multiaxial joint because it allows movement in three planes: flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of motion compared to biaxial joints.
The knee and elbow both are uniaxial joints. This type is a synovial joint that permits movement around only one axis and in only one plane. The articulating ends of the bones form a hinge-shaped unity that allows only flexion and extension.
They have one plane of movement. ex: elbow
an elbow is a u·ni·ax·i·al joint that permits movement around one axis only.
Number of planes in the uniaxial joints?
Flexion ( is a typical of hinge joint ) bending the knee or elbow
It is defined as the ratio of the uniaxial stress over the uniaxial strain in the range of stress in which Hooke's Law holds
Uniaxial crystals have one optic axis, where the refractive index is the same in all directions perpendicular to it. Biaxial crystals have two optic axes, with different refractive indices along each direction. This causes different light paths and behaviors in biaxial crystals compared to uniaxial ones.

The three planes are coronal, sagittal, and transverse (you probably knew this already) so a multiaxial joint can move in all three. So to answer the question, it would be three.
Uniaxial crystals have two different refractive indices: ordinary index (no) and extraordinary index (ne). The ordinary index is the same in all directions, while the extraordinary index varies depending on the direction relative to the optic axis of the crystal. This anisotropic behavior is a characteristic feature of uniaxial crystals.
