Joints were two bones interconnect

Articulations

1

An immovable joint can be fibrous or cartilaginous

Synarthrosis

2

An articulation that permits a small degree of independent movement. 

Amphiarthrosis

3

A freely moveable joint, a synovial joint. 

Diarthrosis

4

Is a synnarthoratic joint located only between the bones of the skull; a fibrous joing between flat bones of the skull. 

Suture

5

A fibrous synarthrosis that binds a tooth to the bone of the jaw. 

Gomphosis

6

Is a rigid, cartilaginous connection between two articulating bones. The ends of the first pair of vertebrosternal ribs and the sternum is a synchondrosis.

Synchondrosis

7

Is a totally ridge immovable joint created when two bones fuse and the boundary between them disappears.

Synostosis

8

Bones are connected by a ligament. Is the distal articulation between the tibia and fibula.

Syndesmosis

9

A fibrous amphiarthrosis, such as that between adjacent vertebrae or between the pubic bones of the coxal bones; The articulating bones are separated by a wedge or pad of fibrous cartilage. 

Symphysis

10

The cartilage pad that covers the surface of a bone inside a joint cavity; reassembles hyaline cartilage. 

Articular cartilages

11

The substnce secreted by synovial membranes that lubricates joints; Resembles interstitial fluid but contains a high concentration of proteoglycans secreted by fibroblasts

Synovial fluid

12

A fibrous cartilage pad betwen opposing surfaces in a joint; Is a pad of fibrous cartilage situated between opposing bones within a synovial joint

Meniscus

13

Are localized masses of adipose tissue covered by a layer of synovial membrane

Fat pads

14

Ligament is stretched to the point at which some collagen fibers are torn

Sprain

15

A small sack filled with synovial fluid that cushions adjacent structures and reduces function; small, fluid-filled pockets in connective tissue

Bursae

16

Is a dislocation in the articulating surfaces are forced out of position

Luxation

17

The damage accompanying a partial dislocation

Subluxation

18

Two opposing surfaces slide past one another

Gliding

19

Is movement in the anterior-posterior plane that reduces the angle between the articulating elements

Flexion

20

Occurs in the same plane but it increases the angle between articulating elements

Extension

21

A movement at a synovial joint in whcih the distal end of the bone moves in a circular direction, but the shaft dose not rotate; Corresponds to the path your arm when you draw a large circle on a chalk board

Circumduction

22

Extension past the anatomical position

Hyperextension

23

Is movement away from the longitudinal axis (midline)  of the body in the frontal plane

Abduction

24

Moven]ment toward the axis or midline of the body; The wrist moves the heel of the hand and fingers toward the body

adduction

25

The rotation of the forearm that makes the palm face posteriorly; Turns the wrist and hand from palm facing front facing back

pronation

26

The rotation of the forarm such that the palm faces anteriorly; The forearm is supinated in the anatomical position

supination

27

Is movement of the thumb toward the surface of the palm or the pads of the other fingers

opposition

28

Entails moving part of the body anteriorly in the horizontal plane

protraction

29

Is the twisting of the foot so the soul turns outward; A turning outward

eversion

30

Is a twisting motion of the foot that turns the soul inward; A turning inward

inversion

31

Movement posteriorly in the horizontal plane; Is opening your mouth

retraction

32

Inferior (downaward) movement of a body part; Is an angle that is going downwards

depression

33

Movement in a super (upward) direction; Is an angle that is increasing

elevation

34

If the posterior longitudinal ligaments are weekened, the compressed nucleus pulposus may distort the anulus fibrous forcing it partway into the vertebral canal

slipped disc

35

A condition caused by intervertebral compression severe enough to rupture the anulus fibrosus and release the nucvleul pulposis, which may protrude beyone the intervetebral space; Sensory nerves are distorted and the protruding mass can also compress the nerves passing through the adjacent intervertebral Forman

herniated disc

36

Partial or complete dislocation of the acromioclavicular joint

shoulder separation

37

A condition characterized by pain in muscles, tendons, bones, or joints; Is a general term that indicates pain and stiffness affecting the skeletal system

rheumatism

38

A group of rheumatic diseases that affect synovial joints; Encompasses all the rheumatic disease that affect synovial joints

arthritis

39

A therapeutic procedure involving the passive movement of an injured joint to stimulate the circulation of synovial fluid; Any injured joint appears to encourage the repair process by improving the circulation of synovial fluid

continuous passive motion

40

The most common pressure-related bursitis, involving a tender nodule formed around bursae over the base of the great toe; is when your big toe points toward the second toe. This causes a bump to appear on the outside edge of your toe

bunion
