Joints and Articulations

Connections and Joint Types

• The connection between a tooth and the jawbone is called a gomphosis.
• Fibrous joints allow very little movement and serve to protect the brain and sense organs.
• Synovial joints are self-lubricating, almost frictionless, and designed to withstand compression while enabling smooth and precise movements.

Joint Classification and Characteristics

• Joints are mainly classified based on their structure (e.g., fibrous, cartilaginous, synovial) and function (e.g., immovable, slightly movable, freely movable).
• The number of joints in the body is primarily determined by age, as the number can change due to growth and development, leading to fusion of some bones.
