Question

choose the accurate statement(s) regarding the types of fibrous joints. check all that apply the attachment of a tooth to its socket is classified as a syndesmoses joint. in syndesmoses joints, the fibers are longer, and the attached bones are more movable. in gomphoses joints, two bones are linked by cartilage. in sutures and gomphoses, the fibers are very short and allow for little or no movement. sutures are immobile, or only slightly mobile, fibrous joints that closely bind the bones of the skull to each other.

Explanation:

1. The attachment of a tooth to its socket is a gomphosis, not a syndesmosis, so the first statement is incorrect.
2. In syndesmoses joints, the fibrous connective - tissue fibers are longer and the bones have more movement compared to other fibrous joints, so the second statement is correct.
3. In gomphoses joints, a tooth is held in its socket by periodontal ligaments, not cartilage, so the third statement is incorrect.
4. Sutures (between skull bones) and gomphoses (tooth - socket) have short fibers allowing little or no movement, so the fourth statement is correct.
5. Sutures are fibrous joints that closely bind skull bones and are immobile or slightly mobile, so the fifth statement is correct.

Answer:

B. In syndesmoses joints, the fibers are longer, and the attached bones are more movable.
D. In sutures and gomphoses, the fibers are very short and allow for little or no movement.
E. Sutures are immobile, or only slightly mobile, fibrous joints that closely bind the bones of the skull to each other.
