The skeleton is held together by joints, which allow for movement. Joints can be classified in two ways. The first is through joint function, also known as the range of motion. The second way to categorize joints is by the material that holds the bones of the joints together; this is a structure-based organization of joints.
The skull has many immovable joints, and connecting various bones is a correct statement.
What is a joint function?
- Synarthrosis (range of joint motion: no movement)- Sutures in the skull, articulations of bony sockets, and teeth in the facial skeleton.
- Amphiarthrosis (range of joint motion: little Movement)- symphysis and the distal joint between the tibia and the fibula.
- Diarthrosis (range of joint motion full movement)- Ankle, elbow, and shoulder.
What are joints grouped by their structure into Fibrous, Cartilaginous, and Synovial Joints?
- Fibrous cartilaginous: Joints that are fibrous. Thin connective tissue exists between the articulations of fibrous joints, which is why most (but not all) fibrous joints are immobile (synarthroses).
- Cartilaginous Joints are those that connect bones with cartilage.
- The presence of an articular capsule between the two joined bones distinguishes synovial joints. A coating of articular cartilage protects the bone surfaces of synovial joints.
Thus, we can conclude that option B is correct.
