A syndesmosis type of joint:
**Core Concept**
A syndesmosis is a type of fibrous joint where two bones are joined together by ligaments, a syndesmosis does not have a joint cavity and the bones are not separated by any cartilage or fibrocartilage. This type of joint provides stability and limited movement.
**Why the Correct Answer is Right**
A syndesmosis is characterized by the presence of ligaments that hold the bones together, such as the distal tibiofibular joint in the lower leg. The ligaments in a syndesmosis allow for some degree of movement, but it is limited compared to other types of joints. The fibrous joint capsule surrounds the bones and ligaments, providing additional stability.
**Why Each Wrong Option is Incorrect**
**Option A:** A synovial joint is a type of joint that has a joint cavity and is characterized by the presence of articular cartilage and a joint capsule, which is not true for a syndesmosis.
**Option B:** A cartilaginous joint is a type of fibrous joint that has a disc of cartilage between the bones, which is not true for a syndesmosis.
**Option C:** A suture is a type of fibrous joint that is found in the skull, where the bones are joined together by dense connective tissue, which is not true for a syndesmosis.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that a syndesmosis is a type of fibrous joint that provides stability and limited movement, and it is characterized by the presence of ligaments that hold the bones together.
**Correct Answer: C. Suture**
