Marfan's syndrome
genetic disorder of human connective tissue
40
What is affected by marfan's syndrome
heart valves and aorta, lungs, eyes, dural sac surrounding the spinal cord, skeleton, and hard palate
41
What physical characteristics do people with marfan's syndrome display
unusually tall, with long limbs and long, thin fingers
42
What causes marfan's syndrome
misfolding of the protein fibrillin-1
43
Articular capsule
outer layer called the fibrous capsule and an inner layer called the synovial membrane
44
Fibrous capsule
dense connective tissue and it strengths the joint to prevent the bones from being pulled apart
45
synovial membrane
connective tissue and lines all parts of the joint cavity except for surfaces of the articulating bones
46
synovial fluid
viscous oily fluid that lubricates the articulating bones and their articular cartilage
47
joint cavity
space that contains a small amount of synovial fluid
48
What type of cartilage is articular cartilage
hyaline cartilage
49
ligaments
connect bone to bone
50
What does ligament men
bands or bandages
51
bursae
saclike structures that contain synovial fluid and are lined by a synovial membrane. help alleviate friction
52
Where are bursae found
between muscles or within an area where a tendon passes over a bone
53
tendon sheaths
modified, elongated bursae that wrap around a tendon to reduce friction
54
fat pads
distributed along the periphery of a synovial joint, and as a packing material and provide some protection for the joint
55
tendons
tendons attach muscle to bone
56
uniaxial
one plane
57
biaxial
two planes
58
multiaxial
two planes and can rotate
59
planar joints (gliding)
intercarpal joints, intertarsal joints, joints between the articulating processes of adjacent vertebrae
60
Hinge joints
uniaxial joints in which the convex surface of one articulating bone fits into a concave depression on the other bone (moves like the hinge of a door)
61
Examples of hinge joints
elbow, knee, ankle, between bones of fingers, metacarpophalangeal joint of finger #1
62
Pivot joints
uniaxial joints in which one articulating bone with a rounded surface fits into a ring formed by a ligament and another bone
63
Examples of pivot joints
proximal radioulnar joint, atlantoaxial joint
64
condyloid joints
biaxial joints with an oval, convex surface on one bone that articulates with a concave articular surface on the second bone of the joint
65
example of condyloid joints
knuckles, radiocarpal joint
66
Saddle joints
biaxial joints that have a concave surface in one direction and a convex surface in another
67
examples of saddle joints
first carpometacarpal joint (on the thumb), sternoclavicular joint, malleus and incus
68
ball-and-socket joints
multiaxial joints in which the spherical articulating head of one bone fits into the rounded socket of a second bone
69
Examples of ball-and-socket joints
hip joint, shoulder joint
70
Gliding
two opposing surfaces sliding back and forth or side to side
71
Example of gliding
carpals and tarsals
