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. The bony edges of this joint are quite close together
or sometimes fused.
c. The connective tissue that binds this joint is the
unossified remnants of the embryonic mesenchymal
membrane in which the bones developed.
d. None of the above is unique to suture joints.
