Question 10

What is the functional name of joints with ‘slight movement’ and name examples.

Answer 10

‘Amphiarthroses’, vertebrae, epiphysis, tibia-fibula and pelvic symphysis.

Question 11

What parts of the body contain slightly moveable joints.

Answer 11

epiphysis, tibia-fibula, pelvic symphysis, vertebrae.

Question 12

What is the functional name of joints with free movement?

Answer 12

‘Diathroses’, all are synovial joints.

Question 13

What is the movement in fibrous joints?

Answer 13

Little or no movement.

Question 14

Types of fibrous joints.

Answer 14

Suture (skull), syndesmosis (tibia & fibula),
gomphosis 9tooth rot in socket)

Question 15

what is the functional classification of the fibrous ‘suture’ joint?

Answer 15

Synarthrosis eg immoveable.

Question 16

what is the functional classification of the fibrous joint ‘syndesmosis (tibia & fibula)’?

Answer 16

Amphiarthrosis ( slight movement).

Question 17

what is the functional classification of the fibrous joint ‘gomphosis (tooth rot)’?

Answer 17

Synarthrosis, immoveable.

Question 18

What type of movement do cartilaginous joints have?

Answer 18

Little to no movement, synarthroses or amphiarthroses.

Question 19

What are the two cartilaginous joints?

Answer 19

Synchondrosis - hyaline cartilage,
symphysis -fibrocartilage.

Question 20

What is the functional name for the cartilaginous joint ‘synchondrosis’ (hyaline cartilage)?

Answer 20

synarthroses, immovable.

Question 21

what is the functional name for the cartilaginous joint, ‘symphysis’ (fibrocartilage)?

Answer 21

amphiathroses , slight movement.

Question 22

What do synovial joints contain?

Answer 22

Synovial cavity,
articular cartilage,
articular capsule,
synovial fluid,
ligaments,
some contain menisci.

Question 23

Describe the disorder ‘Rheumatism’

Answer 23

Any pain from bones, ligaments, tendons , joints or muscles.

Question 24

Describe Arthritis.

Answer 24

Inflammation of joints accompanied by stiffness.

Question 25

Describe Rheumatoid arthritis (RA).

Answer 25

an autimmune disease and is characterised by inflammation of the synovial membranes.

Question 26

Describe osteoarthritis.

Answer 26

A degenerative joint disease characterised by deterioration of the articular cartilage.

Question 28

Describe what happens during the aging of joints.

Answer 28

The synovial fluid production slows, the articular cartilage thins, ligaments shorten and lose flexibility. All of these result in reduced flexibility.
