Flashcards in 7/27 Questions Exam 1 Deck (18):
1

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

Boosted theory

2

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

Boundary theory

3

What are the properties of synovial fluid?

It is yellow-white
viscous
slightly alkaline
tastes salty

4

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

Hyaluronate

5

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

Lubricin

6

What is a simple synovial joint (diarthrosis)?

Only one pair of articulating surfaces are observed

7

What is a complex synovial joint (diarthrosis)?

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

8

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

Nonaxial
Uniaxial
Biaxial
Multiaxial synovial joints

9

What morpholgical classification of synovial joints is classified as nonaxial?

Plane (diarthrosis arthrodial)

10

What morphological classifications of synovial joints would be classified as uniaxial?

Hinge (diarthrosis ginglymus) and pivot (diarthrosis trochoid)

11

What morpholgical classifications of synovial joints would be classified as biaxial?

(Diarthrosis) bicondylar, (diarthrosis) condylar, (diarthrosis) ellipsoidal, and Saddle (diarthrosis sellar)

12

What morpholgical 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

13

What are the examples of synovial pivot (diarthrosis trochoid) joints?

Median atlanto-axial joint and proximal radio-ulnar joint

14

What are the examples of diarthrosis condylar or diarthrosis bicondylar joints?

Temporomandibular joint and Femur-tibia joint of the knee

15

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

16

What are examples of synovial saddle (diarthrosis sellar) joints?

Carpometacarpal joint of the thumb
Talocrural joint of the ankle
Calcaneocuboid joint of the foot

17

What are examples of diarthrosis cotyloid joints?

Femur-acetabulum of the innominate articulation at the hip and the humerus - glenoid cavity of the scapula articulation at the shoulder

18

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
