Q

What are syndesmosis joints?

A

Bones are connected by ligaments, cords in a band of fibrous sheets (interosseous membrane)

Exs:
Interosseous membrane b/n radius and Ulna and b/n tibia and fibula

Q

What is an example of cartilaginous joint for amphiarthrosis?

A

Symphysis joints

17
Q

What are symphysis joints?

A

Ends of articulating bones are covered by hyaline cartilage

Bones are joined by fibrocartilage

Exs:
Pubis symphysis

Intervertebral joints

18
Q

What is a diarthrosis joint?

A

Freely moveable joint

19
Q

What is a type of diarthrosis joint?

A

Synovial joints

20
Q

What are synovial joints?

A

Lined with synovial membrane

Further subdivided based on type of movement

Had a joint cavity surrounded by a fibrous articular capusle

Exs:
