Final answer:
A suture where bone edges overlap and beveled is known as a lambdoid suture, an immobile, fibrous joint that connects skull bones and protects the brain.
Step-by-step explanation:
The term for a suture in which the bone edges are beveled and overlap is called a lambdoid suture. This is an inverted V-shaped joint that unites the occipital bone to the right and left parietal bones on the posterior skull. Sutures, including the lambdoid suture, are immobile, fibrous joints that connect the bones of the skull. They are filled with dense, fibrous connective tissue and form a tight union that prevents most movement between the bones, functionally classified as synarthroses. These fibrous joints are critical for protecting the brain and forming the face.
