What is a synostosis joint
An immobile joint formed when the gap between two bones join together and become a single bone.

What is a diarthrosis (synovial joint)
A point where two bones are separated by a narrow, encapsulated space filled with lubricating synovial fluid; most such joints are relatively mobile. Freely moveable to limited

Knuckles
What is a fibrous joint/synarthosis/synathrodial
A point at which adjacent bones are bound by collagen fibers that emerge from the matrix of one bone, cross the space between them, and penetrate into the matrix of the other.

What are pivot joints
Joint in which a projection of one bone fits into a ringlike of another, allowing one bone to rotate on its longitudinal axis
Examples of pivot joints
