saddle joint (sellar)

Answer 19

convex on concave in one plane and concave on convex in another plane

Question 20

ellipsoidal joint (condyloid)

Answer 20

knuckles: convex surface meets with concave surface

Question 21

planar joint

Answer 21

AC joint, midtarsal, intertarsal, intercarpal

2 flat surfaces meeting with one another. gliding motion

Question 22

uniaxial

Answer 22

motion occurs in one plane around single axis

toes and fingers

Question 23

Answer 23

motion occurs in 2 planes around 2 axes

hand

Question 24

multiaxial

Answer 24

free to move around 3 planes

ball and socket

Question 25

simple

Answer 25

one articular surface on each bony member of joint

Question 26

compound

Answer 26

more than one articular surface on each body member

Question 27

complex

Answer 27

contains an intraarticular disc or cartilage

Question 28

accessory structures

Answer 28

``` meniscus bursa labrum fat pad ligaments tendons ```

Question 29

bursa

Answer 29

fluid filled sacks that help prevent friction

Question 30

labrum

Answer 30

at hip or shoulder, added layer to add depth to the socket

Question 31

fat pad

Answer 31

located within joint capsule itself

Question 32

ligaments

Answer 32

bone to bone

Question 33

tendons

Answer 33

muscle to bone

Question 34

arthrokinematics

Answer 34

"roll or glide" | movement occurs at joint surface during the osteokinematic motion

Question 35

kaltenborn's rule | concave on convex

Answer 35

when a concave surface moves on a fixed convex surface. roll and glide=same direction

Question 36

convex on concave

Answer 36

concave surface is fixed | roll and glide occur in opposite directions

Question 37

goniometry

Answer 37

measurement of angles

Question 38

information from AROM

Answer 38

``` estimate of AROM movements that increase/decrease pain willingness to move coordination attention span muscle strength ```

Question 39

information from PROM

Answer 39

``` amount of movement available quality of motion end feel presence/absence of capsular pattern pain ```

Question 40

end feel (cyriax)

Answer 40

resistance to movement that an examiner feels at the end of a PROM

Question 41

normal end feels

Answer 41

1. bony 2. tissue stretch 3. soft tissue

Question 42

abnormal end feels

Answer 42

empty: limited due to pain bony: occurs prior to when it should capsular: tissue stretch early on ROM springy block: something stuck in the joint spasm/hard: hard end feel when nothing should be blocking area

Question 43

myositis ossificans

Answer 43

blood hardens and begins to feel like bone

Question 44

ROM considerations

Answer 44

``` position of athlete & ATC stabilization alignment of goniometer interpreting data recording data ```

Question 45

stabilization

Answer 45

helps provide isolated movement at that joint provided manually or towels/tables stabilize proximal segment

Question 46

interrater reliability

Answer 46

amount of agreement repeated measurements of ROM by different clinicians

Question 47

intrerater reliability

Answer 47

agreement between repaid measurements of ROM by same clinician

Question 48

lumbarization

Answer 48

S1 is detached from sacral body and acts as an individual vertebra

Question 49

Sacralization

Answer 49

fusion of L5 onto sacrum

Question 50

intervertebral disc layers

Answer 50

``` neurovacular capsule outer annulus fibrosis inner annulus inner nucleus pulposus fibrocartilaginous endplate ```

Question 51

annulus fibrosus

Answer 51

composed of 10-20 layers of rings of fibrocartilage function: protect and isolate the nucleus attaches to outer portion of vertebral bodies high capacity for weight bearing

Question 52

nucleus pulposus

Answer 52

gel like substance, made primarily of water (70-90%) hydrophillic: ability to accept water expands while laying down pressure is greatest when sitting down

Question 53

fibrocartilaginous endplate

Answer 53

covers most of supers and interior portion of disc securing it to vertebral bodies. porous in nature allowing diffusion of nutrients

Question 54

Intervertebral disc (IVD)

Answer 54

bending: nucleus pulposus deforms in the direction opposite of the movement rotating: not well suited for this, only half of the annular fibrosis protect against it

Question 55

joints of lumbar spine

Answer 55

``` intervertebral joints (IV) facet joint (apophyseal joint, zygapophyseal joint) ```

Question 56

IV joints (intervertabral joints)

Answer 56

``` synarthrosis: limited movement cartilaginous symphysis bony members joint also includes IVD and endplates ```

Question 57

facet joints

Answer 57

diarthrodial | planar: gliding movement
