Select the order of functional classes of synovial joints that represents the least number of axes to the most number of axes.
A) nonaxial, uniaxial, biaxial, multiaxial (triaxial)
B) uniaxial, biaxial, multiaxial (triaxial), nonaxial
C) nonaxial, uniaxial, multiaxial (triaxial), biaxial
D) nonaxial, biaxial, uniaxial, multiaxial (triaxial)

Question

Quizplus · Accepted Answer

Nonaxial joints have no axes of rotation, uniaxial joints have one axis of rotation, biaxial joints have two axes of rotation, and multiaxial joints have three axes of rotation. Therefore, the order from least to most axes of rotation is nonaxial, uniaxial, biaxial, and multiaxial.
