1

Articulating ends of bones surrounded by a joint capsule; articular bone ends covered by hyaline cartilage and separated by synovial fluid

Synovial joints

2

Most joints of the skeletal system are

Synovial joints

3

Synovial joints are diarthrotic because they

Allow free movement

4

Synovial joints are more complex structurally than

fibrous or cartilaginous joints

5

Synovial joints consists of

Articular cartilage; a joint capsule; and a synovial membrane, which secretes synovial fluid

6

The articular ends of the bones in a synovial joint are covered with a

Thin layer of hyaline cartilage

7

The thin layer of hyaline cartilage in a synovial joint is called the

Articular cartilage

8

The articular cartilage resists

Wear

9

The articular cartilage minimises

Friction when it is compressed as the joints move

10

Has two distinct layers, holds together the bones of a synovial joint

Joint capsule

11

Reinforce joint capsules

Ligaments

12

Covers all the surfaces within the synovial joint capsule

Synovial membrane

13

The synovial membrane surrounds a closed sac called the

Synovial cavity

14

The synovial membrane secretes a clear fluid called ____ into the synovial cavity

Synovial fluid

15

Contains stem cells, which may function in ligament regeneration following injury

Synovial fluid

16

Synovial fluid has a consistency similar to

Uncooked egg white

17

Moisten and lubricates the smooth cartilaginous surfaces of the joint

Synovial fluid

18

Helps supply articular cartilage with nutrients obtained from blood vessels of the synovial membrane

Synovial fluid

19

The volume of synovial fluid in the cavity of the knee is

0.5 mL or less

20

Separate the articulating surfaces of the femur and tibia

Menisci

21

Some synovial joints are partially or completely divided into two compartments by discs of

Fibrocartilage called menisci

22

The singular of menisci

Meniscus

23

Fluid-filled sacs associated with certain synovial joints

Bursae

24

Singular of bursae

Bursa

25

Cushion and aid the movement of tendons that glide over bony parts or over other tendons

Bursae

26

The names of bursae indicate their

Locations

27

Describe the structure of a synovial joint

Synovial cavity, articular cartilage, a fibrous articular capsule, and ligaments
