Question

what do sutures, gomphoses, and syndesmoses have in common? these are joints found only in the axial skeleton. these are joints found only in the appendicular skeleton. these are all bony joints. these are all fibrous joints. these are cartilaginous joints.

Explanation:

Sutures (between skull bones), gomphoses (teeth - alveolar bone joints), and syndesmoses (bones joined by ligaments) are all types of fibrous joints where bones are connected by dense fibrous connective tissue. Sutures are in the axial skeleton (skull), gomphoses involve teeth (axial skeleton related to the jaw), and syndesmoses can be in both axial and appendicular skeletons. They are not cartilaginous or bony joints.

Answer:

These are all fibrous joints.
