Answer:
person curls his or her fingers, and the phalanges flex at the interphalangeal joints.
Explanation:
Diarthrotic joints found in the skeleton are types of synovial joints. These joints are classified into three categories, based on the number of axes of motion provided by each. They include uniaxial, biaxial and multiaxial
A uniaxial joint allows for a motion in a single plane only. The elbow joint, which only allows for bending or straightening is an example of a uniaxial joint. The curling of fingers and phalanges flexing at interphalangeal joints is a type of uniaxial joint since the bones move in one motion.
