Q

Synovial joint

Diarthrodial joint

A

No direct union between the bones. Instead, there is a capsule filled with synovial fluid.

Q

Hyaline cartilage

Articular cartilage

A

Covers the ends of opposing bones, provides a smooth surface for synovial joints.
Lacks its own blood and nerve supply so it must get its nutrition from synovial fluid…. It can NOT repair itself from damage.

16
Q

Fibrocartilage

A

Acts as shock absorber

Ex: meniscus

17
Q

Labrum

A

Is the shoulder fibrocartilage

Deepens the glenoid fossa

18
Q

Elastic cartilage

A

Help maintain a structures shape

Ex : ear

19
Q

Tendon sheaths

A

Surround the tendon when it is subject to pressure of friction

20
Q

Aponeurosis

A

Broad, flat tendinitis sheet

21
Q

Bursae

A

Small, padlike sacs found around most joints to reduce friction

22
Q

Sagittal, frontal, transverse plane

A

Define and explain

23
Q

Sagittal plane is what axis
Frontal?
Transverse?

A

Frontal
Sagittal
Vertical

24
Q

Dislocation

A

Complete separation of two articular surfaces of a joint.

25
Q

Subluxation

A

Partial dislocation of a joint, usually occurs over time

26
Q

Osteoarthritis

A

Caused by the breakdown and loss of cartilage

27
Q

Sprains

A

Teeing of ligament fibers

28
Q

Strain

A

Over stretching of muscle fibersm

29
Q

Synovitis

A

Inflammation of synovial membrane

30
Q

Tenosynivitis

A

Inflammation of the tendon sheath

31
Q

Give an example f a synarthrodial joint in the axial skeleton

A

Suture of the skull
