intro to joints

Question 1

fibrous joints

Answer 1

bones are only separated by connective tissue with negligible movement

Question 2

cartilage joints

Answer 2

two types: 
primary cartilaginous (synchondrosis) 
secondary cartilaginous (symphysis)

Question 3

synovial joints

Answer 3

1) articular surface covered with hyaline cartilage
2) has a joint cavity with synovial fluid
3) has a joint capsule
4) has a synovial membrane
5) reinforced by ligaments, internally, externally, or both
6) capable of varying degrees of movement

Question 4

classes of synovial joints

Answer 4

1) planar joint
2) hinge joint
3) pivot joint
4) condyloid joint
5) saddle joint
6) ball and socket joint

Question 5

joints of axial skeleton

Answer 5

• atlantooccipital
• atlantaoaxial
• intervertebral
• zygapophyseal (facet)
• inter laminar

Question 6

atlanta-occipital joint location

Answer 6

between the occipital condyles and the lateral masses of the atlas (c1)

Question 7

atlanta-occipital joint function

Answer 7

allows for the nodding action (saying yes)

Question 8

atlantaoaxial joint location

Answer 8

between the atlas and axis (c2)

Question 9

atlantaoaxial joint function

Answer 9

allows for rotation movement of the head when saying no

pivot joint

Question 10

zygapophyseal joints location

Answer 10

between superior and inferior articular facets of adjacent vertebra

Question 11

components of intervertebral discs

Answer 11

outer annular fibrosus (lamella or fibrocartilage)

inner nucleus pulposus (gel like substance)

Question 12

kyphotic

Answer 12

concave anterior

Question 13

lordotic

Answer 13

convex anterior

Question 14

clavicle attaches

Answer 14

limb to torso

Question 15

shoulder (glenohumeral joint)

Answer 15

scapula, humerus

Question 16

elbow joint

Answer 16

olecranon process of ulna and trochlea of humerus

head of radius and capitulum

Question 17

proximal radioulnar joint

Answer 17

head of radius and radial notch on ulna

Question 18

wrist joint

Answer 18

distal end of radius and scaphoid and lunate

Question 19

articulation of glenohumeral joint

Answer 19

between head of humerus and glenoid cavity

Question 20

glenohumeral joint is example of what joint

Answer 20

ball and socket

wide range of movement
stability sacrificed for mobility

Question 21

elbow joint - synovial hinge type

Answer 21

humeroradial and humeroulnar

flexion/extension

Question 22

elbow joint - synovial pivot type

Answer 22

radio-ulnar

pronation/supination

Question 23

articulation of proximal radioulnar joint

Answer 23

between radial head and radial notch on ulna

rotation of radial head in notch results in pronation and supination

Question 24

pelvic girdle

Answer 24

pelvic joints

sacrum

Question 25

hip joint

Answer 25

femur

acetabulum of pelvis

Question 26

knee joint

Answer 26

condyles of femur and tibia

patella (helps with smooth movement of muscle)

Question 27

ankle joint

Answer 27

tibia
fibula
talus

Question 28

hip joint is example of what type of joint

Answer 28

synovial ball and socket

weight bearing joint

Question 29

knee joint between

Answer 29

the femoral condyles and tibial condyles

separated from each other by fibrocartilage menisci

Question 30

knee joint is example of what type of joint

Answer 30

synovial hinge joint
