Joint Structure And Function

Question 0

Diarthrosis

Answer 0

Have 2 layered joint capsule, a joint cavity, synovium lining capsule, synovial fluid, hyaline cartilage and various additional structures

Question 1

Synarthrosis

Answer 1

Nonsynovial; interosseous connective tissue

• fibrous
• cartilaginous

Question 2

Fibrous joints

Answer 2

• suture
• gomphosis
• syndresmosis

Question 3

Suture

Answer 3

Coronal sutures interlock (fused-synostosis)

Question 4

Gomphosis

Answer 4

Tooth and mandible or maxilla

Question 5

Syndesmosis

Answer 5

Ligament, cord, or aponeurotic membrane; tib/fib, radius/ulna

Question 6

Cartilaginous

Answer 6

• symphysis

- synchondrosis

Question 7

Symphysis

Answer 7

Fibrocartilage disk or plates; symphysis pubis; intervertebral joints; manubrium-sternum

Question 8

Synchondrosis

Answer 8

Hyaline growth cartilage that converts to bony union- 1st chondrosternal join

Question 9

Thixotropic properties

Answer 9

Viscosity varies inversely with joint velocity or rate of shear. Rapid-decreased viscosity. Slow- increased viscosity (helps with fine movements)

Question 10

Uniaxial joint

Answer 10

• hinge- IP joints

- pivot (trochoid)- atlas and axis

Question 11

Biaxial joints

Answer 11

Condyloid- MCP joint

Saddle- CMC of thumb

Question 12

Triaxial joints

Answer 12

Plane- carpals and tarsals

Ball and socket- shoulder and hip (circumduction)
