Articulations

Question 1

An Articulation is

Answer 1

Where two or more bones meet

Question 2

Structural classification of joints

Answer 2

Fibrous
Cartilaginous
Synovial

Question 3

Fibrous joint are held together by

Answer 3

collagen fibers

Physical thing that holds the bones together

Question 4

Cartilaginous joints are held together by

Answer 4

Held together by cartilage

Question 5

Synovial joints are held together by

Answer 5

a joint capsule (space between your bones)

Question 6

Functional classification of joints

Amount of movement at the joint

Answer 6

Synarthroses
Amphiarthroses
Diarthroses

Question 7

Synarthroses allow

Answer 7

No movement allowed

Question 8

Amphiarthroses allow

Answer 8

Allow slight movement

Question 9

Diarthroses allow

Answer 9

Freely moveable joints

Question 10

Diarthroses, Amphiarthroses, Synarthroses are all

Answer 10

Synovial joints

Question 11

3 Fibrous joints are

Answer 11

Sutures
Syndesmosis
Gomphoses

Question 12

Sutures are

Answer 12

Where bones have fused together, your suture lines are formed by fibers and are not movable so they are synarthrotic in adults

Question 13

Attributes of Syndesmosis

Answer 13

Held together by ligaments
Are fibrous because made of collagen fibers
Slight movement so they are amphiarthrotic

Question 14

Attributes of Gomphoses

Answer 14

Joints between the teeth and the alveolar socket

Connected by periodontal ligament

Question 15

Types of Cartilaginous joints

Answer 15

Synchondroses

Symphyses:

Question 16

Synchondroses are connected by

Answer 16

hyaline cartilage and do not move

Question 17

Symphyses are connected by

Answer 17

fibrocartilage and allow slight movement

Question 18

Example of Synchondroses

Answer 18

epiphyseal plate and costal cartilages

Question 19

Example of Symphyses

Answer 19

pubic symphysis and intervertebral discs

Question 20

Most of this in our body

Answer 20

Synovial joints

Question 21

Synovial joints are

Answer 21

All diarthroses

Question 22

Articulating bones are separated by

Answer 22

a fluid-containing joint cavity

Question 23

Characteristics of synovial joints

Answer 23

Joint articular capsule
Synovial fluid
Articular cartilage
Reinforcing ligaments
Joint cavity

Question 24

Joint articular capsule

Answer 24

Surrounds the space holding the bones together

Question 25

Synovial fluid function

Answer 25

Lubricates joints | Fills the joint cavity

Question 26

Articular cartilage is

Answer 26

Hyaline cartilage covering the epiphyses

Question 27

Reinforcing ligaments are

Answer 27

Syndesmoses Allow a little of movement And help out synovial joints as well

Question 28

Joint cavities are

Answer 28

space between the bones

Question 29

Optional friction-reducing structures

Answer 29

Bursae Tendon sheath Fatty pads Menisci

Question 30

Bursae

Answer 30

Synovial fluid filled sac

Question 31

Tendon sheath

Answer 31

Fluid filled pouch surrounding a tendon | Still contains some synovial fluid

Question 32

Fatty pads

Answer 32

Adipose tissue within certain joints that help to protect against compression and friction as there’s movement at the joint

Question 33

Menisci

Answer 33

Help cushion knee joint | Fibrocartilage pads

Question 34

Stability of synovial joints

Answer 34

Articular surfaces Ligaments Muscle tone

Question 35

Articular surfaces

Answer 35

How well the bones fit together - the shape Stable: head of femur into coxal bone (acetabelum) Unstable: glenoid fossa and head of humerus

Question 36

Attributes Ligaments

Answer 36

Help hold bones together The less stability the more ligaments The greater the range of motion of the joint the weaker it becomes

Question 37

Muscle tone

Answer 37

Tendons can slightly contribute to joint stability when you contract the muscles
