Flashcards in Arthrology Part 2 Deck (28):
1

What is implied when cartilage is said to have elastic properties

cartilage can deform and returns to original volume rapidly, a time independent property

2

what is implied when cartilage is said to have viscoelastic properties

cartilage can deform and return to original volume slowly, a time dependent property

3

Which theory of joint lubrication implies a loss of fluid from the cartilage into the joint space during compression results in increased viscosity of the synovial fluid

weeping theory

4

Which theory of joint lubrication implies water loss from the synovial fluid increases viscosity of the remaining fluid

boosted theory

5

Which theory of joint lubrication implies an ADsorbtion of lubricant onto cartilage surfaces is responsible for the low-friction observed during movement

boundary theory

6

What are the properties of synovial fluid

it is yellow-white viscous, slightly alkaline, and tastes salty

7

Which substance in synovial fluid was first thought to be responsible for its viscosity and lubricating behavior

hylauronate

8

which substance of synovial fluid has been proposed to be responsible for its viscosity and lubricating behavior

lubricin

9

What is a simple synovial joint (diarthrosis)

only one pair of articulating surfaces are observed

10

What is a compound synovial joint (diarthrosis)

more than two articulating surfaces are present in the same synovial joint

11

What is a complex synovial joint (Diarthrosis)

within the simple or compound joint, the articulating surfaces are seperated by an articular disc (intra-articular disc) or meniscus

12

What are the classifications of synovial joints (diarthroses) based on type of movement)

nonaxial, uniaxial, biaxial and multiaxial synovial joints

13

What movements are accommodated by nonaxial synovial joints

translational movement, a plane or gliding movement

14

What morphological classification of synovial joints is classified as nonaxial

plane (diarthrosis arthrodial)

15

What movements are accommodated by uniaxial synovial joints

a single combination of movements relative to a single axis: flexion extension or medial-lateral rotation

16

What morphological classifications of synovial joints would be classified as uniaxial

hinge (diarthrosis ginglymus) and pivot (diarthrosis trochoid)

17

What movements are accommodated by biaxial synovial joints

movement in two independent planes at right angles to each other: flexion-extension combined with abduction and adduction

18

What morphological classifications of synovial joints would be classified as biaxial

(Diarthrosis) bicondylar, (diarthrosis) condylar, (diarthrosis) ellipsoidal and saddle (diarthrosis Sellar)

19

What morphological classification of synovial joints would be classified as multiaxial

ball and socket (diarthrosis enarthrosis), (diarthrosis spheroidal), (diarthrosis cotyloid) are all classifications given to the same type of joint

20

What are examples of synovial plane (diarthrosis arthrodia) joints

most zygapophyses of the vertebral column intercarpal, carpometacarpal and intermetacarpal joints of the hand inter cuneiform, tarsometatarsal and intermetatarsal joints of the foot.

21

What are examples of synovial hinge (diarthrosis ginglymus) joints

humero-ulnar joint of the elbow and interphalangeal joints of the fingers and toes

22

What are examples of synovial pivot (diarthrosis trochoid) joints

median atlanto-axial joint and proximal radio-ulnar joint

23

What is the shared morphological characteristic of diarthrosis trochoid joints

an osseous pivot point and an osteo-ligamentous ring

24

What are examples of diarthrosis condylar or diarthrosis bicondylar joints

temporomandibular joint and femur-tibia joint of the knee

25

What are examples of diarthrosis ellipsoidal joints

radiocarpal joint of the wrist,
metacarpo-phalangeal joints of the hand, metatarsal-phalangeal joints of the foot
atlanto-occipital joint of the vertebral column

26

Which synovial joint classifications are now often interchanged in textbooks

ellipsoidal and condylar synovial joints

27

What are examples of synovial saddle (diarthrosis sellar) joints

carpometacarpal joint of the thumb
talocrural joint of the ankle
calcaneocuboid joint of the foot

28

What are examples of diarthrosis cotyloid joint

femur-acetabulum of the inominate articulation at the hip
humerus-glenoid cavity of the scapula articulation at the shoulder
