Which joint in the elbow complex is classified as a uniaxial hinge joint?
Understand the Problem
The question is asking to identify which of the listed joints in the elbow complex functions as a uniaxial hinge joint. This requires knowledge of joint biomechanics and the specific structure of each joint listed.
Answer
The humeroulnar joint is a uniaxial hinge joint in the elbow complex.
The humeroulnar joint, specifically the articulation between the trochlea of the humerus and the trochlear notch of the ulna, within the elbow complex is classified as a uniaxial hinge joint.
Answer for screen readers
The humeroulnar joint, specifically the articulation between the trochlea of the humerus and the trochlear notch of the ulna, within the elbow complex is classified as a uniaxial hinge joint.
More Information
Uniaxial hinge joints, like the humeroulnar joint, primarily allow for flexion and extension movements in a single plane, similar to a door hinge.
Tips
A common misconception is that the entire elbow joint is a simple hinge joint. It's important to remember the elbow complex involves multiple articulations, with the humeroulnar joint being the primary hinge joint.
