Key:

b. cartilaginous joints

c. synovial joints 

_____    (1) exhibit a joint cavity 

_____    (2) types are sutures and syndesmoses 

_____    (3) bones connected by collagen fibers 

_____    (4) types include synchondroses and symphyses 

_____    (5) all are diarthrotic 

_____    (6) many are amphiarthrotic 

_____    (7) bones connected by a disc of hyaline cartilage or fibrocartilage 

_____    (8) nearly all are synarthrotic 

_____    (9) shoulder, hip, jaw, and elbow joints

Anatomical characteristics shared by all synovial joints include all except:

a. Articular cartilage

b. A joint cavity

c. An articular capsule

d. Presence of fibrocartilage

The description 'Articular surfaces deep and secure; capsule heavily reinforced by ligaments and muscle tendons; extremely stable joint' best describes

a. The elbow joint

b. The hip joint

c. The knee joint

d. The shoulder joint

Define joint.

Which functional joint class includes freely moveable joints?

Pivot joint     

Hinge joint

a. Uniaxial joint in which the rounded articular surface of one bone fits into a groove of another bone and is held in place by a ligamentous ring

b. Multiaxial joint in which the spherical articular surface of one bone fits into a cup or socket of another bone

c. Nonaxial joint in which two flat surfaces glide over each other

d. Uniaxial joint in which the convex articular surface of one bone fits into a concave articular depression

e. Biaxial joint in which the oval, convex articulating surface of one bone fits into the shallow depression of another bone

f. Biaxial joint in which each articular surface has both convex and concave regions
