Copyright © 2008 Pearson Education, Inc., publishing as Benjamin Cummings Which of the following is a characteristic unique to a suture joint, when compared to a gomphosis or a synostosis? a. This type of joint allows forces to be spread easily with minimal joint movement, thereby decreasing the chance of injury. b.
