QUIZ

Three broad characters of joint (6 subtopics)

Basic structure of joint and where it found an example

How it’s set up

Bonus question: What is an atlantoaxial joint?

It is a type of a pivot joint and is a conical surface of a bone and articulates with a depression of another.

Are the three types of articulation moving from least moveable to most moveable?

(Statement and blank)

None (synarthroses)

Slightly (amphiarthroses)

Freely (diarthroses)

Synarthroses

Articulation bones in close contact bound to thin layer of fibrous tissue or cartilage

No movement

Suture b/w bone of the skull: Epiphyseal plate

Amphiarthroses

Articulation bone are separation by fibrocartilaginous disks or bound by interosseous ligament

Slightly moveable

Intervertebral joints: symphysis pubis and sacroiliac joints between tibia-fibula and radius-ulna

Diarthroses

Joint capsule containing synovial membrane and fluid

Freely moveable

Gliding

Flattened/ slightly curved articulating surface

Sliding

Intercarpal and intertarsal joints

Hinge

Concave surface of bone articulating convex surface of another bone

Bending motion in one plane

Knee; elbow joints of phalanges

Pivot

Conical surface of one bone articulates depression of another

Rotation about a central axis

Atlantoaxial joint: proximal radioulnar joint

Condyloid

Oval condyle of bone articulates with elliptical cavity of another

Biaxial movement

Radiocarpal joint

Saddle

Concave and convex surface on each articulating bone

Wide range of movements

Carpometacarpal joints of the thumb

Ball and socket

Rounded convex surface of one bone articulates with cuplike socket of another

Movement in all planes and rotation

Shoulder and hip joints
