14
Q

Shiny, whitish connective tissue that protects underlying bone, absorbs shock, allows movement, and is designed to last (also can wear away over time). No nerves or blood vessels.

16
Q

A clear coloured, slippery fluid with the consistency of egg-white. Found in the joint cavity and acts as a lubricant to minimize friction between 2 joint surfaces.

A

Synovial Fluid

17
Q

What are the 6 types of synovial joints?

A

1) Condyloid (aka. Ellipsoid)
2) Saddle
3) Ball and Socket
4) Plane
5) Pivot
6) Hinge (aka. Ginglymus)

18
Q

A synovial joint that is biaxial. Conducts flexion/extension & abduction/adduction motions.

A

Condyloid (aka. Ellipsoid)

19
Q

The knuckles are an example of a ________ joint, which falls under synovial joints.

A

Condyloid (aka. Ellipsoid)

20
Q

A synovial joint that is biaxial. Has opposing surfaces (concave/convex) that articulate with each other.

A

Saddle

21
Q

The thumb is an example of a ________ joint, which falls under synovial joints.

A

Saddle

22
Q

A synovial joint that is multiaxial. The spheroidal surface articulates with the socket of the other surface.

A

Ball and Socket

23
Q

The hip is an example of a ________ joint, which falls under synovial joints.

A

Ball and Socket

24
Q

A synovial joint that is mostly uniaxial. Conducts gliding or sliding movements and the joint surfaces are essentially flat.

A

Plane

25
Q

The carpals are examples of ________ joints, which fall under synovial joints.

A

Plane

26
Q

A synovial joint that is uniaxial. Conducts rotations where a rounded process rotates within a sleeve or ring.

A

Pivot

27
Q

C1-C2 is an example of a ________ joint, which falls under synovial joints.

A

Pivot

28
Q

A synovial joint that is uniaxial. Conducts flexion and extension motions only.

A

Hinge (aka. Ginglymus)

29
Q

The fingers are examples of ________ joints, which fall under synovial joints.

A

Hinge (aka. Ginglymus)

30
Q

A sac filled with synovial fluid that decreases friction generated by the motion of one tissue over another. Normally it is flat, but it can become inflamed.

A

Bursa

31
Q

Typically found in high traffic areas, such as the knee, hip, ankle or shoulder.

A

Bursa

32
Q

Where are the 3 locations of bursae?

A

1) Between tendons and bony prominences
2) Between tendons and other tendons
3) Between bone and overlying skin

33
Q

Connect bone to bone and will prevent excessive movement in a specified direction.

A

Ligaments

34
Q

When a joint is moved beyond its normal range of motion.

A

Sprain

35
Q

A joint position where the ligaments and joint capsule are tight and the joint has maximal articular surface contact. There is increased stability, but decreased mobility.

A

Close-Packed Position

36
Q

Extension of the knee is an example of ________ position.

A

Close-Packed

37
Q

A joint position where the ligaments and joint capsule are loose and the joint has maximal space and available movement. There is increased mobility, but decreased stability.

A

Loose-Packed Position

38
Q

Flexion of the knee is an example of ________ position.

A

Loose-Packed
