Lecture 8-9

Question 1

What is a joint?

Answer 1

A point of connection between two joints (articulation). The strands of connective tissue, ligaments, hold the bones together and ensure the stability of joints.

Question 2

What are 3 classifications of joints?

Answer 2

1. Fibrous joints
2. Cartilaginous joints
3. Synovial joints

Question 3

How much movement do fibrous joints allow for?

Answer 3

No movement (sutures of the skull)

Question 4

How much movement do cartilaginous joints allow for?

Answer 4

Limited movement (intervertebral discs between right and left pubis bones)

Question 5

How much movement do synovial joints allow for?

Answer 5

A Large range of motion (hip joint)

Question 6

What does the joint capsule in a synovial joint do?

Answer 6

Allows for lubrication of the joint. Also may have thickenings which add support (intrinsic ligaments).

Question 7

What are some examples of special feature which some joints have?

Answer 7

Articular discs, fibrocartilaginous labra, menisci, and intrscapular tendons

Question 8

What is joint cavity?

Answer 8

Space filled with synovial fluid.

Question 9

What is the synovial membrane?

Answer 9

Covers the joint cavity and secretes the lubrication fluid

Question 10

What is hyaline cartilage?

Answer 10

A protective layer of dense white connective tissue that covers the ends of the articulating bones.

Question 11

What is synovial fluid?

Answer 11

Lubricates the joint and increasing during times of stress.

Question 12

What is the capsule?

Answer 12

Something which may or may not have thickenings called intrinsic ligaments

Question 13

What are extrinsic ligaments?

Answer 13

Support the joint and connect the articulating bone
