Answer:

To summarize, a joint united by dense cartilaginous tissue that permits virtually no movement is called a symphysis (option D)

Step-by-step explanation:

A joint united by dense cartilaginous tissue that permits virtually no movement is called a symphysis. A symphysis is a type of joint where the bones are connected by fibrocartilage, a tough and flexible type of cartilage.

One example of a symphysis joint is the pubic symphysis, which connects the two pubic bones in the pelvis. The fibrocartilage between the pubic bones provides stability and support, but allows for a small amount of movement during activities like walking or giving birth.

In contrast, a synovial joint (option A) is a joint that allows for free movement and is surrounded by a joint capsule containing synovial fluid. Examples of synovial joints include the knee, elbow, and shoulder joints.

A suture (option B) is a type of joint found only in the skull, where the bones are tightly interlocked by fibrous connective tissue. Sutures allow for very little movement and provide stability to the skull.

A syndesmosis (option C) is a joint where the bones are connected by a ligament or fibrous membrane. Examples of syndesmosis joints include the tibiofibular joint in the lower leg and the radius-ulna joint in the forearm.

To summarize, a joint united by dense cartilaginous tissue that permits virtually no movement is called a symphysis (option D). It is important to understand the different types of joints and their characteristics to have a comprehensive understanding of the human skeletal system.
