condyloid joint saddle joint thumb metacarpal trapezium gliding joint tarsus navicular 2nd cuneiform 1st cuneiform wrist scaphoid radius lunate

condyloid joint click to hear : condyloid joint

An example is the wrist, which the hand can move on two axes: flexion and extension; it can also be tilted sideways (toward the radius and ulna).

saddle joint click to hear : saddle joint

Resembles the condyloid joint but allows a wider range of motion; this type of joint is rare.

thumb click to hear : thumb

The thumb is an example of a saddle joint.

metacarpal click to hear : metacarpal

Each of the five bones forming the metacarpus. The metacarpal bone of the thumb is very mobile.

trapezium click to hear : trapezium

Bone of the anterior row of the carpus articulating especially with the metacarpal bone of the thumb.

gliding joint click to hear : gliding joint

Surfaces of these joints are relatively flat and not very mobile; they allow only a narrow gliding range (e.g., vertebrae, certain bones of the carpus).

tarsus click to hear : tarsus

Gliding joints that ensure the displacement of certain bones of the tarsus.

2nd cuneiform click to hear : 2nd cuneiform

Bone of the anterior row of the tarsus articulating especially with the metatarsal bone of the second toe and the scaphoid bone.

1st cuneiform click to hear : 1st cuneiform

Bone of the anterior row of the tarsus articulating especially with the metatarsal bone of the big toe and the scaphoid bone.

wrist click to hear : wrist

Condyloid joint of the hand (carpus) articulating with the forearm (radius); it mainly enables the hand to flex and extend.

scaphoid click to hear : scaphoid

Bone of the posterior row of the carpus articulating especially with the radius to form the wrist.

radius click to hear : radius

Long bone making up the outer section of the forearm; it is connected especially to the carpal bones to form the wrist joint.

lunate click to hear : lunate

Bone of the posterior row of the carpus articulating especially with the radius to form the wrist.
