your elbow joint is an example of a(n) ______ joint.
options:

• uniaxial
• multiaxial
• biaxial
• nonaxial

Explanation:

The elbow joint (a hinge joint) allows movement in one plane (flexion and extension), so it is a uniaxial joint. Multiaxial joints allow movement in multiple planes (e.g., shoulder), biaxial in two planes (e.g., wrist), and nonaxial have no angular movement (e.g., sutures in skull).

Answer:

A. uniaxial
