Activity 8

Question 1

What are the structural joint classifications?

Answer 1

• based on the structure of morphology of the join
  1. fibrous
  2. cartilaginous
  3. synovial

Question 2

Describe fibrous joints and give the three types

Answer 2

• bones are connected by fibrous connective tissues with fibers of varying length, no joint cavity
  1. sutural
  2. syndesmosis
  3. gomphosis

Question 3

Describe cartilaginous joints and give the 2 types

Answer 3

• bones are connected by cartilage, no joint cavity
  1. synchondrosis
  2. symphysis

Question 4

describe synovial joints

Answer 4

bones are held together by a complex joint cavity

Question 5

Answer 5

• fibrous
  sewing together or seam

Question 6

Answer 7

• fibrous
  bolting together; tooth

Question 8

What kind of joint is synchondrosis and what does it mean

Answer 8

• cartilaginous
  held by cartilage

Question 9

What kind of joint is symphysis and what does it mean

Answer 9

• cartilaginous
  growing together

Question 10

What are the functional joint classifications

Answer 10

1. synarthosis
2. amphiarthosis
3. diarthosis

Question 11

Describe synarthrosis

Answer 11

1 .virtually no movement
2. Used when describing fibrous or cartilaginous joints

Question 12

Describe Amphiarthrosis joints

Answer 12

1. allows slight give at the joint
2. Used when describing fibrous or cartilaginous joints

Question 13

Describe Diarthrosis joints

Answer 13

1. joint with variable movement of the joint cavity
2. used when describing all synovial joints
3. can be further classified based on movement or structural subclasses
