Skeletal (W3.2)

Question 1

Articulation

Answer 1

place where bones come together

Question 2

Fibrous joint

Answer 2

(synarthrose) united tissue with no movement

ex - skull, splint bones and cannon

Question 3

Cartilaginous joint

Answer 3

(amphiarthrose) united fibrocartilage or hyaline cartilage with slight movement; capable of only a slight rocking movement
ex - symphsis (pelvis) or intervertebral joints

Question 4

Synovial

Answer 4

(diarthroses) united by a synovial joint capsule, freely movable

Question 5

Joint Capsule

Answer 5

surrounds joint with outer fibrous and inner synovial membrane

Question 6

Fibrous layer

Answer 6

attaches to periosteum

Question 7

Synovial membrane

Answer 7

highly vascular, nerve rich and produces synovial fluid

Question 8

Synovial fluid

Answer 8

lubricates joint, supplies nutrients and removes waste from hyaline articular cartilage

Question 9

Articular cartilage Of the synovial joint

Answer 9

Hyaline covering of articulating ends of bones; reduces concussion and friction

Question 10

Intracapsular ligament

Answer 10

within joint capsule

Question 11

Extracapsular ligament

Answer 11

outside joint capsule

Question 12

Joint cavity (of the ligament)

Answer 12

(aka joint space)

potential space containing synovial fluid

Question 13

Meniscus (of the ligament)

Answer 13

aka disc

fibrocartilage dividing joint cavity, greater variety of motion (TMJ and stifle)

Question 14

Bursa

Answer 14

sac like structure to reduce friction between structures
Fibrous layer lined with synovial membrane
between bones and skin, ligaments, tendon, or muscle

Question 15

Synovial sheath

Answer 15

similar to bursa but wraps around tendon

Question 16

Ankylosis

Answer 16

natural bony fusion of joint

Question 17

Arthrodesis

Answer 17

surgical bony fusion of joint

Question 18

Luxation

Answer 18

articular separation (patella)

Question 19

Arthrocentesis

Answer 19

joint tap, removal of fluid from joint by sterile means

Question 20

Bursitis

Answer 20

inflammation of bursa

Question 21

FHO

Answer 21

Femoral Head Osteotomy

muscles acting as hip joint after femoral head removed

Question 22

False Joint

Answer 22

?? surgical procedure

Question 23

Flexion

Answer 23

decreases angle

Synovial joint movement

Question 24

Extension

Answer 24

increases angle

Synovial joint movement

Question 25

Adduction

Answer 25

toward median

Synovial joint movement

Question 26

Abduction

Answer 26

away from median

Synovial joint movement

Question 27

Rotation

Answer 27

twist on axis

Synovial joint movement

Question 28

Circumduction

Answer 28

distal end moves in circle

Synovial joint movement

Question 29

Supinate

Answer 29

move palm side up

Synovial joint movement

Question 30

Pronate

Answer 30

move palm side down

Synovial joint movement

Question 31

Universal

Answer 31

all movements

Synovial joint movement

Question 32

Hinge synovial joint

Answer 32

joint swivels around another
only flexion and extension possible
(elbow and alantooccpital- yes movement)

Question 33

Gliding synovial joint

Answer 33

rocking motion
joint surfaces flat; flexion and extension mainly with minimal abduction and adduction
ex carpus and tarsus

Question 34

Pivot synovial joint

Answer 34

one joint rotates or pivots on another; only rotation

ex - atlantoaxial joint (no movement)

Question 35

Ball and socket synovial joint

Answer 35

most extensive movement (universal as allow flexion, extension, adduction, abduction, circumduction, and rotation
ex - hip and shoulder
