Definition of Rib
Rib: One of the 12 paired arches of bone which form the skeletal structure of the chest
wall (the rib cage). The ribs attach to the building blocks of the spine (vertebrae) in the
back. The 12 pairs of ribs consist of:


True ribs: The first seven ribs attach to the sternum (the breast bone) in the front
and are known as true ribs (or sternal ribs).
False ribs: The lower five ribs do not directly connect to the sternum and are
known as false ribs.
The upper three false ribs connect to the costal cartilages of the ribs just above them.
The last two false ribs, however, usually have no ventral attachment (no anchor at all in
front) and are called floating, fluctuating or vertebral ribs.
Definition of Joint
A joint is the area where two bones are attached for the purpose of motion of body parts.
A joint is usually formed of fibrous connective tissue and cartilage. An articulation or an
arthrosis is the same as a joint.
Joints are grouped according to their motion: a ball and socket joint; a hinge joint; a
condyloid joint (a joint that permits all forms of angular movement except axial rotation);
a pivot joint; gliding joint; and a saddle joint.
Joints can move in four and only four ways:




Gliding -- one bony surface glides on another without angular or rotatory movement;
Angular -- occurs only between long bones, increasing or decreasing the angle
between the bones;
Circumduction -- occurs in joints composed of the head of a bone and an articular
cavity, the long bone describing a series of circles, the whole forming a cone; and
Rotation -- a bone moves about a central axis without moving from this axis.
The word "joint" comes from the Latin "junctio" meaning a joining (as in a junction).
