Chapter 8: Classifying Joints

Question 1

synarthrosis

Answer 1

joints that don’t move at all.

Question 2

diarthrosis

Answer 2

freely movable joint.

Question 3

amphiarthrosis

Answer 3

slightly movable joint

Question 4

fibrous joint

Answer 4

held together tightly by dense connective tissue. Pretty much no movement (so synarthrosis)

Question 5

cartilaginous joint

Answer 5

a pad of cartilage holds bones together in this type of joint. Pretty much no movement (synarthrosis).

Question 6

synovial joint

Answer 6

these joints contain synovial fluid and allow considerable movement (diarthrosis).

Question 7

what are the characteristics of fibrous joints?

Answer 7

1) connective tissue
2) little to no movement
3) no joint cavity

Question 8

What are the three types of fibrous joints?

Answer 8

1) sutures

2) syndesmoses

3) gomphoses

Question 9

sutural ligament

Question 10

synostosis

Answer 10

when sutures ossify as in adults

Question 11

fontanels

Question 12

syndesmosis

Answer 12

bones are further apart with some movement. Bones held together by ligaments.

Question 13

gomphoses

Answer 13

“peg in socket” joint like a tooth in the jaw…what else? not a lot of movement. Ex. Periodontal ligaments.

Question 14

what are the two types of cartilaginous joints?

Answer 14

synchondroses
symphyses

Question 15

synchondroses

Answer 15

hyaline cartilage joint
little to no movements (synarthrosis)
ex. epiphyseal plates of growing bones. Most are temporary as the hyaline cartilage is transformed into a synostosis joint as the tissue ossifies.

Question 16

symphysis

Answer 16

contains fibrocartilage, some movement. This is a pad between two movements
Ex. intervertebral disks

Question 17

synostosis

Answer 17

when a suture ossifies. Usually in older people.
