25
fossa
surface depression
26
fibroblasts
collagen-producing cells of fibrous connective tissue
27
fibrocartilage
cartilage containing a relatively high collagen fiber content; it is relatively compressible and resistant to stretch
28
force
action that alters the state of rest or motion
29
growth factors
substances that promote bone growth and remodeling during development and fracture repair; produced by cells found primarily in bone, fibrous connective tissue, and blood vessels
30
hematoma
mass of clotted blood that forms at an injury site following disruption of blood vessels
31
hematopoiesis
process of forming the blood cells of the body
32
hormones
organic molecules released into the blood that act as chemical messengers to regulate specific body functions
33
hyaline
most abundant cartilage type in the body; semitransparent and somewhat stiff, it provides firm support
34
hydroxypatite
mineral part of bone composed of hard, calcium phosphate and calcium hydroxide crystals that form on collagen fibers in bone matrix
35
hyoid bone
U-shaped bone in the net that supports the root of the tongue...it is not articulated by any other bone but is supported by the next muscles
36
inferior
positioned away from the head, toward the feet
37
insertion
distal attachment point of a muscle; opposite of origin
38
joint stability
structural integrity of a joint and the degree to which it resists exceeding its normal range of motion
39
kinematics
description of body movement without considering forces that caused the movement
40
ligaments
fibrous connective tissue bands that span joints, adhering to articular ends of bones; they limit the degree of movement and contribute to joint stability
41
lipids
fat
42
load
force applied to an object
43
matrix
material that fills the spaces between connective tissue cells, consisting primarily of fibrous proteins, proteoglycans, fluid, and other molecules
44
metaphysis
portion of a long bone between the epiphysis and diaphysis; it is continuous with the epiphysis in an adult
45
minerals
inorganic substances that exhibit a crystalline strucutre and characteristic color and hardness; salts
46
nociceptive
stimulating specific pain receptors by injury to a body tissue
47
ossification
process of forming bone tissue
48
origin
proximal attachment point of a muscle
49
osteoblasts
bone-producing cells; immature bone cells
50
osteoclasts
bone-removing cells
51
osteocytes
mature bone cells
52
osteogenic cells
immature stem cells in bone that differentiate and become osteoblasts
53
osteons
basic units of cortical bone, each consisting of a central canal and surrounding lamellae
54
osteoid
component of bone matrix produced and secreted by osteoblasts; consists of a fluid containing primarily collagen fibers and proteoglycans
55
periosteum
double-layered membrane covering the entire external bone except for the joint surfaces
56
phagocyte
type of white blood cells that engulfs and digests debris or foreign substances to remove them from a tissue site
57
posterior
toward the back of the body
58
proprioceptive
stimulating specific receptors within muscles, tendons, and joint capsules that provide information on body movements
59
proteoglycans
molecules found in connective tissues, consisting of a core protein surrounded by polysaccharides; the higher the polysaccharide content, the more gelatinous the tissue
60
range of motion
amount of normal rotational movement allowed in each plane for a given joint; typically expressed in degrees, relative to a zero point
61
receptors
peripheral nerve endings of sensory neurons specialized to detect and respond to specific stimuli
62
sacrum
wedge-shaped bone formed by the fusion of the five sacral vertebrae
63
subchondral bone
bone directly beneath and cartilaginous surface; usually referring to the bone beneath the articular cartilage
64
superior
positioned toward the heady away from the feet
65
suture
immovable fibrous joint; characteristic of most skull joints
66
synarthroses
immovable joints made by fibrous or cartilage connective tissue
67
synovial joints
freely movable joints characterized by the presence of a joint cavity and articular capsule
68
tendons
dense fibrous connective tissue cords that connect skeletal muscles to bone; typically extend from each end of the muscle to the bone surface; where they fuse with the periosteum
69
tendon sheath
specialied fluid filled sacs (bursae) that surround tends subjected to friction
70
torque
force acting about an axis of rotation
71
trabeculae
small spikes or plates of bone that collectively form the infrastructure of cancellous bone; the lines seen in trabeculae show stress patterns
72
valgus
angular deformity of the limb..AWAY from the midline "knock-kneed"
73
varus
angular deformity of the limb....TOWARDS the midline "bow-legged"
74
vascular
rich blood supply
