Joints are classified according to what?

structure or function

2

What are the three different structures of joints

Fibrous Connective Tissue
Cartilage
Articular Capsule with Synovial Fluid

3

What are the three different functions off joints?

Synarthrosis
Amphiarthrosis
Diarthrosis

4

What does synarthrosis mean, and what structure is this?

Doesn't move
Fibrous Connective Tissue

5

What does amphiarthrosis mean, and what structure is this?

Partially moveable
Cartilage

6

What does diarthrosis mean, and what structure is this?

Fully moveable
Articular Capsule with Synovial Fluid

7

Fibrous joints are those in which... ?

bones are connected by fibrous tissue with no joint cavity

8

What are the three types of fibrous joints?

sutures
syndesmosis
gomphosis

9

What is a suture?

dense fibrous connective tissue between skull bones

10

What are syndesmosis?

interosseous membrane between radius and ulna

11

What are gomphosis?

root of tooth in jaw
-peg-in-socket joint

12

What are cartilaginous joints?

Joints connected entirely by cartilage
-more moveable than fibrous joints
-less moveable than synovial joints

13

What is an epiphyseal line?

An epiphyseal plate that has been ossified to stop growing

14

What are symphysis?

partially moveable joint made of fibrocartilage

15

synovial joints consist of what?

-Articular cartilage on ends of bones
-A joint capsule consisting of tough fibrous connective tissue and a secreting synovial membrane.

16

What are bursae?

A saclike structure containing synovial fluid

17

What are bursae for?

protect skin, tendons, bones, from structures that could rub against them

18

how are synovial joints classified?

according to shape and articulating surfaces

19

pivot joints consist of what?

rounded bone surface fitting into a ring

20

what is a condylar join?

an oval convex surface that articulates with a concave surface

21

what is an example of a saddle joint?

thumb and trapezium

22

ball and socket joints allow movement on how many axis?

3 axis

23

what are the three types of movements?

angular movement
circular movement
special movement

24

what are angular movements?

flexion and extension
abduction and adduction
circumduction

25

what are circular movements?

rotation
pronation and supination

26

what are special movements?

elevation and depression
protraction and retraction
excursion

27

the knee joint is formed by articulation with what?

tibial and femoral condyles

28

the articular capsule is reinforced by what?

capsular ligaments

29

what do the tibial and fibular collateral ligaments help prevent?

hyperextension
abduction
adduction of the leg

30

the cruciate ligaments help prevent what?

anterior-posterior displacement of joint surfaces
[also help knees lock when standing]
