Question

The Focus Figure of Synovial Joints has examined a number of types of movement and the joints in which they are located. Review the types you have studied, and select a true statement or characteristic of uniaxial movement in a representative joint. The dancer's leg is lifted to a ballet bar. A person curls his or her fingers, and the phalanges flex at the interphalangeal joints. A golfer swings at the ball on the tee. A person bends over, and his or her vertebral processes move past one another.

Answer 1

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.
