Structural Classification of Joints:
Fibrous joint - The fibrous joint is present between nearby bones and is connected by the dense
connective tissue. It lacks a synovial cavity so it has little to no movement.
Cartilaginous joint - The cartilaginous joint is present between the bones and is connected by the
hyaline cartilage. It has no synovial joints, but allows little movements.
Synovial joint - The synovial joint is present between bones where it allows free movement. Has
synovial cavity making it freely moveable. These types of joints are divided into 6 categories that
are based on their movements: plane, hinge, pivot, condyloid, saddle, and ball and socket joint. A
plane joint is flat or slightly curved, allowing for back-and-forth and side-to-side movement
between the flat surfaces of bones. A hinge joint is a convex surface of the bone that fits into the
concave surface. Like a hinged door, it creates angular and open-close action while only
allowing flexion-extension movement. A pivot joint is A ring created by another bone and the
ligament articulates with the rounded/pointed surface of one bone. It can only be rotated around
its longitudinal axis. A condyloid joint is one bone's oval-shaped protrusion that fits into another
bone's oval-shaped depression. It's a bi-axial, meaning it can move about two axes. A saddle joint
is one bone's articular surface resembles a saddle, and the other bone fits into it. The movements
are biaxial, allowing for limited circumduction and flexion-extension as well as abduction-
