ulna click to hear : ulna

Long bone forming the inner portion of the forearm articulating especially with the humerus.

pivot joint click to hear : pivot joint

Enables rotation around a lengthwise axis: the cylindrical terminal part of a bone is encased in a hollow cylinder. Examples include the tibia and the fibula.

ball-and-socket joint click to hear : ball-and-socket joint

Allows movement along three axes, such as in the elbow: flexion and extension, rotation, and adduction (arm drawing near the trunk) and abduction (arm drawing away from the trunk).

hinge joint click to hear : hinge joint

Enables flexion and extension along a single axis. The elbow is a particularly good example: the round terminal part of the humerus turns in the hollow of the ulna.

shoulder click to hear : shoulder

Example of a ball-and-socket joint, between the humerus and the thorax.

humerus click to hear : humerus

Long arm bone articulating with the scapula to form the shoulder, and with the radius and the ulna to form the elbow.

scapula click to hear : scapula

Large thin flat bone articulating with the clavicle and the humerus to form the shoulder; numerous shoulder and back muscles are attached to it.

leg click to hear : leg

Example of a pivot joint, between the fibula and the tibia.
