the outer layer of the capsule if made up of what?

A

fibrous dense CT

2
Q

the outer layer is continuous with what<

A

the periosteum of the adjacent bone

3
Q

the synovial membrane (layer) is the what? covering what?

A

inner connective tissue layer covering non-articular surfaces

4
Q

The synovial membrane is rich in what?

A

blood, nerve supply and lymphatics

5
Q

the synovial layer will do what if damaged?

A

will regenerate rapidly

6
Q

the synovial layer is considered an epithelial lining? t/f

A

False

7
Q

what are the two cell types found in the synovial layer?

A

Type A synovocytes and Type B synovocytes

8
Q

Type A synovocytes are what type of cell?

A

They are macrophages

9
Q

what is the function of type a synovocytes?

A

to remove debris from joint space y phagocytosis

10
Q

Type B synovocytes resemble what type of cell?

A

fibroblasts (= synovial cell)

11
Q

what is the function of type B synovocytes?

A

secrete synovial fluid

12
Q

synovial fluid is made up of what?

A

high concentrations of hyaluronan (HA) and lubricin (glycoproteins)

13
Q

what is the function of synovial fluid?

A

to act as a joint lubricant and to supply nutrients and oxygen to chondrocytes

What are the three types of synovial membranes (synoviums)?

A

Fibrous, areolar and adipose

15

A

made up of dense irregular CT and covering tendons and ligaments

16
Q

the areolar synovium is made up of what and is covering what?

A

made up of loose areolar CT with Type A and B cells and it extends into joint cavity as synovial folds and villi

17
Q

The areolar synovium is extends into the joint cavity when what occurs?

A

when there is movement

18
Q

The adipose synovium has what types of cells present? and covers what?

A

has type B cells present and covers intra-articular fat pads
