a rounded process of one bone rotates within a sleeve of another

Question 4

Answer 4

uniaxial (gliding / sliding)
ie: AC joint
flat surfaces of bone articulate

Question 5

Describe a hinge joint

Answer 5

uniaxial (flexion / extension)
ie: elbow joint
movements around a single axis

Question 6

Answer 6

biaxial (flexion / extension, abduction / adduction)
two saddle shaped surfaces articulate (concave and convex)
ie: CMC joints

Question 7

describe a condyloid joint

Answer 7

biaxial (flexion / extension, abduction / adduction)

oval shaped condyle fits into an elliptical cavity
ie: MCP joint

Question 8

describe a ball and socket joint

Answer 8

multiaxial (flexion / extension, abduction / adduction / internal and external rotation, circumduction)

ie: glenohumeral joint
