Question 4

Suture

Answer 4

Fibrous Joint
Articulating bones connected by thin layer of dense irregular connective tissue
Some replaced by synostosis
Coronal sitire

Question 5

Syndesmosis

Answer 5

Articulating bones connected by more dense irregular connective tissue, like a ligament

Question 6

Interosseous membrane

Answer 6

Articulating bones united by substantial sheet of dense irregular connective tissue
Between tibia and fibula

Question 7

Synchondrosis

Answer 7

Connecting material is hyaline cartilage
Becomes synostosis when bone elongation ceases
Epiphyseal plate between epiphysis and diaphysis of long bone

Question 8

Symphysis

Answer 8

Connecting material is fibrocartilage

Pubic symphysis and intervertebral joints

Question 9

Plane Joints

Answer 9

Articulated surfaces are flat or slightly curved

Intercarpal, intertarsal, sternocostal, vertebrocostal

Question 10

Hinge

Answer 10

Convex surface fits into concave surface
Knee
Elbow
Ankle

Question 11

Pivot

Answer 11

Rounded or pointed surface fits into ring formed partly by bone and partly by ligament
Radioulnar joint

Question 12

Condyloid

Answer 12

Oval shaped projection fits into oval-shaped depression

Radiocarpal and metacarpophalangeal joints

Question 13

Saddle

Answer 13

Articular surface of one bone is saddle shaped, articular surface of other bone sits in saddle
Carpometacarpal joint between trapezium and metacarpal of thumb

Question 14

Ball and socket

Answer 14

Ball-like surface fits into cuplike depression

Shoulder and hip joints
