Study Notes
Types of Joints
- Amphiarthrotic and Synarthrotic: Examples of these joint types are categorized as cartilaginous joints.
- Synovial Joints: These joints are characterized by a fibrous capsule that is lined with a synovial membrane, enclosing a joint cavity.
Fibrous Joints
- Joint Structure: Fibrous joints consist of bone regions joined together by fibrous connective tissue.
- Skull Bone Connections: The joints formed between the skull bones are specific types of fibrous joints known as sutures.
- Protection: Fibrous joints, particularly sutures, provide maximum protection for underlying structures.
Synovial Joints
- Examples: Common synovial joints include the hip, elbow, and knee, showcasing a wide range of mobility.
- Specific Joints: The joint between the atlas and axis, which are cervical vertebrae, is classified as a synovial joint.
- Mobility: Synovial joints are categorized as diarthroses, meaning they are freely movable.
- Reinforcement: Synovial joints are strengthened by surrounding ligaments, contributing to stability.
- Fluid Presence: Many synovial joints contain fluid-filled cushions, such as bursae, to reduce friction during movement.
- Limb Joints: The majority of joints found in the limbs are synovial joints, promoting a high degree of mobility.
Cartilaginous Joints
- Pubic Symphysis: This joint serves as an example of a cartilaginous joint, specifically classified as a symphysis.
- Growth Plate: A child's long-bone growth plate is composed of hyaline cartilage, highlighting a temporary cartilaginous joint structure.
Joint Mobility and Function
- Greatest Mobility: Synovial joints are noted for their extensive mobility, which is important for a wide range of movements.
- Axial Skeleton Functionality: Synovial joints are not typically found in the axial skeleton because this skeletal portion prioritizes support and protection over mobility. Strength is emphasized in these structural joints.
Synovial Joint Types
- Categories: Synovial joints are classified into several types, including:
- Ball and socket
- Ellipsoidal
- Hinge
- Pivot
- Saddle
- Gliding
