Joint
Make it clearer
A joint is a point of connection where two bones, or a bone and cartilage, meet to form part of the skeleton.
Think of different mechanical connections. Some hold their pieces nearly fixed, some allow a small amount of movement, and others move freely. That is why joints are classified both by their structure and by the degree of movement they permit.
In brief
A joint is the place where two bones, or a bone and cartilage, meet to form a connection.
Joints are classified by their structure and by how much movement they allow, from immovable to freely movable.
Think of a mechanical connection between structures: depending on the type, some remain nearly fixed, while others allow a wide range of movement between the bones.
