The slightly movable articulations in which the contiguous bony surfaces are either connected by broad flattened disks of fibrocartilage or united by interosseous ligaments are known as
## **Core Concept**
The question tests knowledge of the classification of joints, specifically focusing on the characteristics of slightly movable articulations. These joints are part of the body's skeletal system and are crucial for providing support and facilitating movement.
## **Why the Correct Answer is Right**
The correct answer, **C. Symphyses**, describes a type of cartilaginous joint. Symphyses are characterized by the presence of broad, flattened disks of fibrocartilage that connect the contiguous bony surfaces. This type of joint allows for slight movement and provides strong support and stability. Examples include the intervertebral discs and the symphysis pubis.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Fibrous joints (synarthroses) are characterized by being immovable or having very limited movement, and the bones are joined by dense connective tissue. This does not match the description given.
- **Option B:** Synovial joints are highly movable and contain a fluid-filled space between the articulating bones, which is not described in the question.
- **Option D:** Syndesmoses are a type of fibrous joint where bones are connected by ligaments, but they do not typically involve broad flattened disks of fibrocartilage.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that symphyses, such as the symphysis pubis, can be affected by conditions like osteitis pubis, which causes pain and stiffness in the pubic area, often due to overuse or pregnancy.
## **Correct Answer:** . Symphyses
