Q

hinge joint

A

round circular end of bone the articulates with the concave of a bone; unla and humerous

17
Q

Pivot joint

A

a circular bone that fits to a concave bone but only allows rotation along the axis

18
Q

condylar joint

A

Condylar structure that fits into an oval depression of the other bone
Allows for flexion, extension, abduction and adduction

19
Q

Saddle joint

A

The opposing bone surfaces are reciprocally concave and convex
Allows for flexion, extension, abduction and adduction (little rotation is done)

20
Q

Ball and socket joint

A

Ball shaped head that fits into a cup like depression
Allows for flexion, extension, abduction, adduction, circumduction and rotation

21
Q

Tibiofemoral

A

Knee joint

22
Q

Glenohumeral

A

Shoulder joint

23
Q

Coxal joint

A

Hip Joint
