Q

Synovial fluid

A

Secreted by the synovial membrane. Consists of hyaluronic acid. Lubricates the joint and prevents friction. Absorbs shocks during movement.

20
Q

Hinge joints

A

Produce an opening and closing motion like that of a hinged door.

21
Q

Pivot joints

A

Surface of one bone articulates with a ring-shaped part of another bone

22
Q

Ball-and-socket joints

A

A ball-like head of one bone fits into a cup-like depression of another bone. Allow for a large variety of movements

23
Q

Tempromandibular joint

A

Hinge joint formed by the consumer process of the mandible and the mandibular fossa of the temporal bone. Only moveable joint between skull bones

24
Q

Articular discs

A

Pads of fibrocartilage that lie between articulating surfaces of the bones in some synovial joints.

25
Q

Shoulder joint

A

A ball-and-socket joint is formed by the head of the humerus and the glenoid cavity. Shallow

26
Q

Bursae

A

Sac-like structures that contain fluid similar to synovial fluid.

27
Q

Elbow joint

A

Hinge joint formed by the humerus, ulna, and the radius

27
Q

Hip joints

A

Deep ball-and-socket joint formed by the head of the femur and the acetabulum of the hip bone.

28
Q

Knee joint

A

A hinge joint formed by the lateral and medial consoles of the femur.

29
Q

Flexion

A

Decreasing the angle between articulating bones

30
Q

Extension

A

Increasing the angle between articulating bones

31
Q

Hyperextension

A

Continuation of extension beyond the anatomical position

32
Q

Lateral flexion

A

Movement of the trunk sideways to the right or left at the waist

33
Q

Abduction

A

A movement of a bone away from the midline

34
Q

Adduction

A

A movement of a bone toward the midline

35
Q

Elevation

A

Upward movements of body parts

36
Q

Depression

A

Downward movement of a part of the body

37
Q

Protraction

A

A movement of a part of the body anteriorly thrusting the mandible forward

38
Q

Retraction

A

Movement of a protracted part of the body back to the normal anatomical position

39
Q

Supination

A

Movement of the forearm so that the palm turned upward

40
Q

Pronation

A

Movement of the forearm so that the palm is turned facing down

41
Q

Supinated position

A

The radius and ulna are parallel to each other

42
Q

Pronated position

A

The radius over the ulna

43
Q

Inversion

A

The movement of the sole of the feet, so that you are standing on the outer edge of the foot

44
Q

Eversion

A

The movement of the sole of the foot, so the sole of the foot points to the outside

45
Q

Doesuflexion

A

The bending of the goot at the ankle in an upward direction

46
Q
