Joints and types of Joints
By Kevin Wilson 6R

Joints

A joint or articulation (or articular surface) is the location at which bones connect. They are constructed to allow movement (except for skull, sacral, sternal, and pelvic bones) and provide mechanical support, and are classified structurally and functionally.
Ball and SocketJoint
The ball and socket joint (or spheroidal joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. It enables the bone to move in many places (Nearly all directions).

Pivot Joint
Pivot joints allow for rotation, protraction, retraction,twist, flexion, extension, adduction and abduction, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward). When rotating the forearm, these movements are typically called pronation and supination. In the standard anatomical position, the forearms are supinated, which means that the palms are facing forward, and the thumbs are pointing away from the body. In contrast, a forearm in pronation would have the palm facing backward and the thumb would be closer to the body, pointing medially.

Hinge Joint

A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend.

Types of Joints
* Ball and Socket Joint

*Hinge Joint

* Pivot Joint

* Gliding Joint
Gliding Joint
A gliding joint, also known as a plane joint or planar joint, is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. Gliding joints allow the bones to glide past one another in any direction along the plane of the joint – up and down, left and right, and diagonally. Slight rotations can also occur at these joints, but are limited by the shape of the bones and the elasticity of the joint capsule surrounding them.
