Flashcards in JOINTS Deck (36):
1

If there is a "cavity" between skeletal elements this is called ?

synovial joint

2

if there is NO cavity between two skeletal elements this is called ?

solid joint

3

What are the general characteristics of synovial joints /

hyaline cartilage covers the articulating surfaces
joint capsule consisting of synovial membrane and fibrous membrane
membrane attaches to margins of the surfaces and produces a fluid
fibrous membrane- surround and stabilizes the joint

4

plane joints

allow sliding and gliding when bones move across the surface of another (acromioclavicular)

5

hinge joints

allow movement around ONE axis permits flexion and extension (elbow joint

6

pivot joints

movement around one axis that passes longitudinaly along the shaft of the bone; permits rotation (atlantoaxial joint)

7

bicondylar joints

allow movement in one axis and limited movement in another (knee joint) formed by two convex condyles articulating with two concave flat surfaces

8

condylar joints

allow movement around two axes that are at right angles to each other (extension, flextion, abduction adduction and limited circumduction
(wrist joint)

9

saddle joint

allows movement around two axes that are at right angles, articular surfaces are saddle shaped, allows everything as condylar but also circumduction (thumb)

10

ball and socket joints

allow movement around multiple axes Hip joint is an example

11

fibrous joints

sutures gomphoses, and syndesmoses

12

cartilagenous joints

synchondroses and sympheses

13

sutures

in skull; adjacent bones are linked together by a thin layer of connective tissue

14

gomphoses

teeth and adjacent bone

15

syndesmoses

two adjacent bones are linked by a ligament

16

synchondroses

two ossification centers remain separated by cartilage

17

sympheses

two separate bone are interconnected by cartilages

18

sternoclavicular joints

innervation-subclavian and supraclavicular
modified ball and socket
blood supply-internal thoracic, suprascapular, supreme thoracic and clavicular branch of thoracromial artery

19

acromioclavicular joint

plane joint
blood supply- lateral thoracic, acromial branch of thoracoacromial
innervation- axillary n, supraclavicular nerve, lateral pectoral nerve

20

Glenohumeral joint (shoulder joint)

ball and socket
blood supply- suprascapular artery and anterior/posterior circumflex humeral arteries
innervation-suprascapular, axillary and lateral pectoral nerve

21

coracohumeral ligament

blends with capsule of shoulder

22

coracoacromial ligament

roof of joint prevents superior dislocation

23

transverse humeral ligament

holds the biceps tendon in the intertubercular groove

24

glenohumeral ligaments

thickened parts of the articular capsule which is visible from inside the joint

25

elbow joint

compound joint

26

What is the arterial supply to the elbow joint

formed by 7 arteris
superior ulnar collateral
inferior ulnar collateral
radial collateral
middle collateral
ulnar recurrent artery
radial recurrent artery
interosseous recurrent artery

27

What is the innervation of the elbow joint

all of the antebrachial nerves
ulnar, radial, median and musculocutaneous nerve

28

Distal radioulnar joint

pivot joint
blood supply- anterior and posterior interosseous arteris
innervation- median and radial nerves

29

radiocarpal joint

ellipsoid joint (biaxial)

30

carpus metacarpus joint

plane joint

31

carpometacarpal joint of pllex

biaxial saddle joint

32

distal interphalangeal joints

hing joint

33

proximal interphalangeal joints

hinge joint

34

metacarpophalangeal joints

ball and socket in shape

35

facet or zygapophysial joints

synovial joint/gliding
innervated by dorsal rami

36

what innervates the vertebral disks ?

sympathetic vertebral plexus; sinuvertebral nerves from ventral ramis
