Joints
Gliding joint (intercarpal)
A gliding joint, also known as a plane joint, is a type of movable joint where flat or nearly flat bone surfaces slide past each other to allow limited, non-angular movement. Ex. Carpal bones
Frontal bone
Forms the forehead
Hinge joint (humeroulnar)
A hinge joint is a type of synovial joint that allows bones to move in just one direction, much like a mechanical hinge on a door.
Ex. Humerus and Ulna
Parietal bones
form the roof and upper sides of the cranium
Pivot Joint (radioulnar)
A pivot joint is a type of synovial joint where a cylinder-shaped bone rotates inside a ring formed by another bone and a ligament.
Ex. Radius and Ulna
Condylar joint (metacarpophalangeal)
A type of movable joint where an oval-shaped bone end fits snugly into a matching shallow cup-like socket of another bone.
Ex. Phalanx and Metacarpal bone
Saddle joint (trapeziometacarpal)
A type of synovial joint where one bone's surface is concave and the other bone's surface is convex, fitting together like a rider in a saddle.
Ex. Metacarpal and carpal bone
