20
Q

What are the three types of joints?

A

-fibrous
-cartilaginous
-synovial

21
Q

What are the characteristics of fibrous joints?

A

-fibrous connective tissue between bones
-designed for stability; no movement

22
Q

What are examples of fibrous joints?

A

-sutures between flat bones of skull
-gomphosis between tooth root and socket
-syndesmosis holding short bones together

23
Q

What are the two types of cartilaginous joints?

A

-symphysis
-synchondrosis

24
Q

What are the characteristics of symphysis joints?

A

-held together by fibrocartilage
-ossify with age

25
Q

What are examples of symphysis joints?

A

-mandibular symphysis
-pelvic symphysis
-intervertebral discs

26
Q

What are the characteristics of synchondrosis joints?

A

-held together by hyaline cartilage
-programmed to ossify

27
Q

What is an example of a synchondrosis joint?

A

physeal cartilage in long bones

28
Q

What is the purpose of cartilaginous joints?

A

-provide stability
-no movement

29
Q

What are the characteristics of synovial joints?

A

-designed for mobility
-no tissue joining bone to bone

30
Q

What are the parts of a synovial joint?

A

-articular cartilage (hyaline)
-fibrous portion of joint capsule
-synovial membrane of joint capsule
-joint cavity

31
Q

What other structures can exist within a synovial joint?

A

-fibrocartilaginous discs
-intra-articular ligaments
-extra-capsular ligaments
