Directions: After reading section 7.13 from your textbook use both the information contained in the reading
as well as your notes, to answer the following questions.
1.
a) List the functional classifications for joints.
b) List the structural classification of joints.
c) Which type of classification is used more commonly?

in certain specific synovial joints (ex: knee).
3.
List each of the six types of synovial joints and give one example for each.
4.
Complete the following statements.
a) A ___________________________________ of the skull is an example of an immovable fibrous
joint.
b) Structurally, the joint between the first rib and the sternum is ____________________________.
c) Functionally, the band at the joint at the distal tibia and fibula is synarthrosis. What is it structurally?
__________________________________.
d) Intervertebral discs are composed of ___________________________________.
e) ___________________________________ acts as a joint lubricant in synovial joints.
f) The discs of fibrocartilage between the articulating surfaces of the knee are called
___________________________________.
g) The fluid-filled sacs sometimes associated with synovial joints are called _________________.
h) Structurally, the symphysis pubis is an example of a(n) _______________________________ joint.
i) Functionally, the symphysis pubis is an example of a(n) _______________________________ joint.
j) Articular cartilage is composed of ________________________________ tissue (1 of the 4 main types).
