1

types of solid joints

fibrous and cartilaginous

2

fibrous joints composition

solid, limited movement

sutures, syndesmoses, composes

develop from cartilaginous (adults)

3

cartilaginous joint composition

synchondroses
symphyses

4

synovial joints

joint capsule
hyaline cartilage
some have articular disc
typically mobile

5

joint capsule is composed of

inner synovial membrane
outer fibrous capsule

6

3 functional classifications of joints

synarthrosis
amphiarthrosis
diarthrosis

7

amphiarthrosis

joints with little movement

8

synarthrosis

joints with no movement

9

diarthrosis

joints with lots of movement

i.e. synovial joints

10

nonaxial

joint with no axis of movement

11

uniaxial

joint with single axis of movement

12

biaxial

joint with 2 axes of movement

13

multiaxial

>2 axes of movement

14

6 joints of the upper limb

acromioclavicular
glenohumerol (shoulder)
elbow
radioulnar (proximal)
radioulnar (distal)
sternocalvicular

all are synovial, diarthrotic

15

acromioclavicular joint

articulating bones

acromion process of scapula, clavicle

16

acromioclavicular joint

structural type

synovial, plane

17

acromioclavicular joint

functional type and movements allowed

diarthrotic, gliding and rotation of scapula

18

scapula and humerus compose which joint

shoulder

19

shoulder joint structural type

synovial
ball and socket

20

movements allowed by shoulder joint

multiaxial, flexion, extension, abduction, adduction, circumduction, rotation of humerus/arm

21

elbow articulating bones

ulna and radius with humerus

22

elbow structural type

synovial
hinge

23

movements allowed by elbow

uniaxial
flexion , extension of forearm

24

what muscles groups are considered shoulder

axioappendicular
scapulohumeral

25

axioappendicular

connect axial skeleton to the upper limp

anterior structures of pectoral region
posterior structures of back

26

scapulohumeral muscles

connect scapula to humerus

27

bursae in the shoulder

fluid filled sacks

subacromial
sub deltoid
subcoracoid
subscapular

28

subacromial bursa

space between acromion and supraspinatus tendon
very fragile

29

sub deltoid bursa

between deltoid muscle and joint capsule

very large

30

subcoracoid bursa

between subscapularis muscle and coracoid process
may be fused with sub scapular bursa
