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. 1) The dancer's leg is lifted to a ballet bar. 2) A person curls his or her fingers, and the phalanges flex at the interphalangeal joints. 3) A golfer swings at the ball on the tee. 4) A person bends over, and his or her vertebral processes move past one another.

Answer 1

A person curls his or her fingers, and the phalanges flex at the interphalangeal joints.

The interphalangeal joints are synovial hinge-shaped joints that serve as the articulation between the phalanges. synovial joints allow a considerable degree of movement. the synovial fluid lubricates the joint, absorbs shock and supplies nutrients t articular cartilage. Common synovial joints are hinge points, ball and socket joints and pivot joints. The interphalangeal joint's function to optimize the gripping of the hand since the joint allows flexion and extension.
