Question

most skull bones are joined by tight connections called
symphyses.
synchondroses.
sutures.
gomphoses.
syndesmoses.

Explanation:

Symphyses are cartilaginous joints found in places like the pubic symphysis. Synchondroses are also cartilaginous joints, such as the growth plates in bones. Gomphoses are the joints that anchor teeth to the jaw. Syndesmoses are fibrous joints connecting bones with ligaments, like the tibiofibular joint. Sutures are the tight, fibrous joints that specifically connect most skull bones, allowing minimal movement and securing the skull structure.

Answer:

sutures.
