sketletal Flashcards
Osteoporosis
Bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes
Paget Disease
Chronic bone disorder that disrupts the replacement of old bone tissue with new bone tissue
osteogenesis imperfecta
Is is an inherited disorder characterized by extreme fragility of thee bones.
Oteomyelitis
The inflammation of bone or bone marrow, usually due to an infection.
Osteonecrosis
It is the death of bone tissue due to lack of blood supply.
Bone tumors
It is a mass of unusual cells growing in a bone.
Rickets
It is a condition that affects bone development in children.
Osteomalacia
When adults bone soften because vitamin D deficiency.
Achondroplasia
It is a hereditary condition in which the growth of long bones is restricted by ossification of cartilage.
Hyperostosis
This is when there is too much growth of bony tissue.
Acromegaly
The abnormal growth of the hands, feet, and face, caused by overproduction of growth hormone by the pituitary gland.
Scoliosis
The abnormal lateral curvature of the spine.
Flexion
bending at a joint to decrease the angle of the parts
Extension
bending at a joint to increase the angle of the parts
Dorsiflexion
bring the foot towards the shin (walking on heels)
Hyperextension
extension of parts of a joint beyond normal
Plantar flexion
takes the foot away from the shine (walking on toes)
abduction
at a joint, move a part from the midline
Adduction
Move a part towards the midline
Rotation
moving a part on an axis (twisting head)
circumduction
moving a part so its ends forms a circular path
pronotation
palm downward
supination
palm upward
Eversion
turning foot so the surface faces laterally
Inversion
turning the foot so the plantar surface faces medially
elevation
to raise a part towards a superior direction (shoulders up)
depression
to lower a part towards an inferior direction (shoulders down)
protraction
movement of a part in the anterior direction (Head forward)
retraction
movement of a part in the posterior direction (head back)
Hinge joint
Permits movement only one plane (ankle and elbow)
ellipsoid
a reduced ball and socket configuration (knee and wrist joints)
saddle joint
a carpometacarpal joint at the base of the thumb, almostions but rotation
ball and socket joint
movements in all directions are permitted (hip and shoulder)
pivot
ring bone around a peg, radial head pivots
Gliding
the facet joints of the vertebrae (wrist bones and ankle)
fibrous
slight twisting (skull)
greenstick
incomplete fracture, the break occurs on the convex suface of th bend in bone
fissured
an incomplete fracture is a longitudinal break
communited fracture
a complete fracture and fragments the bone
transverse fracture
a complete fracture, and the break occurs at the right angle to the axis of the bone (horizontal)
oblique fracture
occurs at a diagonal angle
spiral fracture
caused by excessive twisting of a bone
sinus
cavity within a bone
condyle
rounded process that usually articulates with another boen
formamen
opening through a bone that usually is a passageway for blood vessels, nerves, or ligaments
Ligaments
a type of fibrous connective tissue that joins bones together at joints
tendons
a type of fibrous connective tissue that attaches muscle to bone
epicondyle
projection situated above a condyle
crest
narrow, ridgelike projection
facet
small, nearly flat surface
fontanel
soft spot in the skull where membranes cover the space between bones
fossa
relatively deep depression or pit
fovea
tiny pot or depression
head (hed)
enlargement on the end of the bone
meatus
tubelike passageway within a bone
process
prominent projection on a bone
spine
thornlike projection
trochanter
relatively large process
suture
interlocking line of union between bones
tubercle
small, knoblike process
tuberosity
knoblike process usually larger than a tubercle
trabeculae
branching bony plates
medullary cavity
a hollow chamer
endosteum
thin layer of cells
intramembranous bones
flat bones of the skull
osteoblast
bone- forming cells
osteocytes
when extracellular matrix completely surrounds osteoblasts
osteoclasts
break down extracellular matrix
levers
when bones and muscles interact as mechanical devices when the body parts move
hematopoiesis
process of blood cell formation
amount of ribs
24
true ribs
first 7 attached directly to the sternum
false ribs
5 false ribs their cartilage do not reach the sternum directly
floating ribs
2 ribs they have no cartilaginous attachments
synovial joints
allow free movement
cartilaginous joints
bones joined together by cartilage
cervical
seven of them (smallest)
Thoracic
12 (medium)
Lumbar
5 (biggesta0)
