Fibrocartilage is not found in a synovial joint. Hence, option E is correct.
<h3>What is synovial joint?</h3>
A synovial joint, sometimes referred to as diarthrosis, joins bones or cartilage with the help of a fibrous joint capsule that encloses the articulating surfaces of the linked bones and forms the outer boundary of a synovial cavity.
In synovial joints, long bones can articulate inside a fluid-filled space. In order to facilitate easier joint movement, the connective tissue known as articular cartilage that covers the ends of bones acts as a load-bearing, low-friction, and wear-resistant surface.
Thus, option E, Fibrocartilage, is correct.
