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
Ethmoid bone
forms part of the nose, eye socket, and floor of the cranium
palatine bone
forms the posterior part of the hard palate in the mouth
costals
The twelve pairs of ribs that attach posteriorly to the thoracic vertebrae
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
Nasal Bone
Forms the bridge of the nose
Lacrimal bones
make up part of the eye socket. Each lacrimal bone contains a channel through which tears flow
true ribs
The three pairs of ribs that attach anteriorly to the costal cartilage
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
Occipital bones
form the posterior floor and walls of the cranium
Vomer bone
the septum, or dividing line, between the left and right cavities of the nose
sternum
forms the breastbone
thorax
The skeletal structure that makes up the rib cage, containing the sternum, ribs, and thoracic vertebrae
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
Temporal bones
forms the sides and base of the skull, and the floor and sides of the eye sockets.
zygomatic bone
are the cheekbones
manubrium
The uppermost part of the sternum
Lacrimal bones
make up part of the eye socket. Each lacrimal bone contains a channel through which tears flow
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
Sphenoid bone
forms part of the base
maxillary & mandible
mandible- the lower jawbone
maxillary- form the upper jawbone
xiphoid
The lowermost part of the sternum
thoracic vertebrae
made up of 12 vertebrae, serve as the posterior attachment for the ribs
