Flashcards in Joints - possible quiz Deck (51):
1

What is a simple joint

a joint that includes two skeletal structures

2

composite joint

involve 3 or more skeletal structures

3

3 types of joints

firbrous, cartilaginous, synovial

4

fibrous joints aka

synarthroses

5

synovial joints aka

diarthroses

6

arthrology

study of joints

7

movement in fibrous joints

none

8

3 subtypes of synarthroses joints

syndesmoses, sutres, and gomphoses

9

Syndesmoses

fibrous joints with a relatively large amount of fibrous connective tissue between the skeletal components

10

locations of syndesmoses

side to side joints between the radius and ulna, and the tibia and the fibula

11

Sutures

fibrous joints between flat bones of the skull

12

how many sutures can be derived from their names

33

13

4 subtypes of sutures

serrated suture, squamos suture, planar suture, schindylesis

14

serrated sutures

bones are united by interlocking processes resembling the teeth of a saw or pieces of a puzzle. (sagittal suture)

15

Squamous sutures

bones met in beveled overlapping edges ( articulation between the parietal bone and the squamous portion of the temporal bone on each side of the skull

16

planar sutures

simple apposition of the articulating bones with no overlapping and no interlocking

17

schindylesis

varient type of suture in which a thin plate of bone articulates in a cleft of another one

18

Gomphoses

the fibrus joints between teeth and the bony sockets in which they are embedded (dental alveoli)

19

dentoalveolar joints

called peg joints because of the configuration

20

periodontium

thin layer of connective tissue proper which glues the roots of a tooth into the alveolus is termed the periodontal membrane

21

how are cartilaginous joints united? (2)

hyaline cartilage, and fibrocartilage

22

Hyaline Cartilage joints aka

synchondroses - uniting tissue is hyaline cartilage

23

example of hyaline cartilage joint

chondral joints, epiphyseal cartilage,

24

fibrocartilage joints

aka symphyses, the skeletal structures are united by fibrocartilage

25

examples of fibrocartilage

intervertevral symphyses, pubic symphysis, manubriosternal symphysis

26

synovial joints

aka diarthroses, joints are united by fibrous connective tissue but also have articular (synovial) cavity between the articulating surfaces

27

what do cells of the synovial membrane secrete

synovial fluid

28

what is synovial fluid

joint fluid, synoviu

29

what is the synovial fluid secreted

into the joint cavity, this fluid lubricates and nourishes the relatively thing avaxcular articular artilage

30

how thick is the avascular cartilage

1-2 mm thick

31

what are synovial joints reinforced by

ligaments

32

what are ligaments

fibrous connective tissue bands

33

capsular ligaments

the fibrous layer of the joint capsule

34

extracapsular ligaments

located on each side of the major plane of motion in a joint, often termed collateral ligaments

35

intracapsular ligaments

internal to the fibrous part of the joint, present in the coxal, genual, tarsal and carpal joints.

36

what does collateral ligaments mean

on both sides of the joint

37

movement of synovial joints

freely moveable

38

what are the 2 types of cartilaginous joints

synchondrosis, Symphysis

39

how types of synovial joints are there

7

40

what is distinguishing about syndesmosis

fibrous joints with a relatively large amount of fibrous connective tissue

41

what is distinguishing about sutures

4 diff kinds, fibrous joints between flat bones of the skull

42

what is distinguishing about gomphosis

fibrous joints between teeth and bony sockets where they are embedded

43

what is distinguishing about synchondrosis

hyaline cartilage, uniting connective tissue is hyaline cartilage

44

what is distinguishing about symphysis

skeletal structures united by fibrocartilage, intervertebral symphyses, pubic symphyses, and the manubriosternal symphysis

45

firbrocartilaginous structures

between the articular surface of the skeletal components, some synovial joints improved by its presence. Purpose is to fill in the gaps and to help spread synovail fluid over the articular surface

46

Articular disks

when fibrocartilaginous structures completely separate the articular cartilages and thereby subdivide they articular cavity

47

articular disks locations

radiocarpal joints, acromiocalvicular joints, sternocalicular joints, and the temporomandibular joints

48

articular menisci

two incomplete articular disks, do not completely separate the femoral condyle from the tibial condyles

49

articular menisci location

genual joint

50

5 parts of synovial joints

capsular ligaments, extracapsular ligaments, intracapsular ligaments, articular disks, and articular menisci

51

What is articular discs

When structures completely separate the articular cartilages and thereby subdivide the articular cavity
