The Skeleton Joints

Question 1

Ways to classify joints

Answer 1

Structional - based on intervening tissue

Functional - based on the range of motion

Question 2

Synarthrosis

Answer 2

Fixed Joint - Functional

Question 3

Amphiarthrosis

Answer 3

Slightly Moveable - Functional

Question 4

Diathrosis

Answer 4

Freely Moveable - Functional

Question 5

Fibrous

Answer 5

Held together with fibrous tissue
Suture- found in the skull
Syndesmosis- found between the tibia and the fibular
Gomphosis- found where teeth join to the bony socket

Question 6

Cartilaginous

Answer 6

Held together with cartilage

Question 7

Synovial

Answer 7

made with a joint capsule and cavity containing synovial fluid

Question 8

Uniaxial

Answer 8

1 degree of freedom

Question 9

Biaxial

Answer 9

2 degrees of freedom

Question 10

Multiaxial

Answer 10

3 degrees of freedom

Question 11

Gliding Joints

Answer 11

have flat or slightly curved surfaces and the surfaces slide across each other

Question 12

Hinge Joints

Answer 12

give angle motion in a singular plane allowing for flexion and extension

Question 13

Pivot Joints

Answer 13

this joint allows for rotation eg supination and pronation

Question 14

Ellipsoid Joints

Answer 14

a oval articular face rests in a depression allowing for angular motion within two planes

Question 15

Saddle Joint

Answer 15

two surfaces sit together like a rider in a saddle allows for circumduction but not rotation

Question 16

Ball and Socket Joint

Answer 16

a round head of a one rests within the cup shaped depression of another allows for angular and rotational movements
