Joint classifications

Question 1

List the 3 types of joints in the musculoskeletal system

Answer 1

Fibrous
Cartilaginous
Synovial

Question 2

This joint has the least amount of movement

Answer 2

Fibrous

Question 3

This joint has some movement

Answer 3

Cartilaginous

Question 4

This joint has the most amount of movement

Answer 4

Synovial

Question 5

Covers bone ends where they articulate

Answer 5

Hyaline cartilage

Question 6

Outer layer of DFCT
Inner layer of synovial membrane

Answer 6

Joint capsule

Question 7

Which synovial joint structure
- secretes synovial fluid
- lubricates joints
- sends nutrients to avascular structures

Answer 7

Joint capsule

Question 8

Explain how cartilage gets nutrients

Answer 8

Cartilage can not get nutrients from blood however, synovial fluid contains a lot of the same nutrients that blood does, so when you bend a joint the joint capsule pushes the synovial fluid into the cartilage to try and keep it healthy

Question 9

Have them for support when want to restrict movement

Answer 9

Capsular ligaments

Question 10

Restricts movement away from themselves

Answer 10

Ligaments

Question 11

Inside capsule, holds bones together inside joint

Answer 11

Intrascapular ligaments

Question 12

a ligament in the center of the knee that prevents the shin bone (tibia) from moving forward on the thigh bone (femur)

Answer 12

Anterior cruciate ligament

Question 13

Stops femur from sliding backwards

Answer 13

Anterior cruciate ligament

Question 14

Stops femur from sliding forwards

Answer 14

Posterior cruciate ligament

Question 15

Not cartilaginous joints, different type of joint but made of the same material

Answer 15

Fibrocartilaginous pads

Question 16

Half moon shaped structures that sit in between femur and tibia

Answer 16

Fibrocartilaginous pads

Question 17

2 key functions of fibrocartilaginous pads

Answer 17

Makes up for poor bone congruency
Shock absorption

Question 18

Structure and function of fibrous joints

Answer 18

No movement
Ligament

Question 19

Structure and function of cartiliaginous joints

Answer 19

Some movement
Fibrocartilage

Question 20

Structure and function of synovial joints

Answer 20

Most movement
joint capsule
ligaments
synovial membrane and fluid
maybe fibrocartilage
hyaline cartilage
