What is the term for the type of joint that permits slight movement but is less flexible than synovial joints?

The term for the type of joint that permits slight movement but is less flexible than synovial joints is correctly identified as cartilaginous joints. These joints are characterized by the presence of cartilage that connects the articulating bones, allowing for limited motion compared to the free-moving nature of synovial joints, which are highly lubricated and allow for a wider range of motion.

Cartilaginous joints are found in areas such as the intervertebral discs of the spine and the pubic symphysis. Here, the cartilage acts as a cushion and provides some flexibility, but not to the extent found in synovial joints, which are designed for more dynamic and extensive movement.

In contrast, diarthrodial joints, which are another name for synovial joints, allow for considerable movement. Fibrous joints, on the other hand, are typically immovable and feature bones connected by dense connective tissue. Therefore, the distinction lies in the degree of movement allowed, emphasizing that cartilaginous joints permit slight movement, making them less flexible than synovial joints.
