ch. 5 Flashcards
flat bone
ribs, scapula, pelvic girdle, skull bones
long bone
tibia, femur, humerus, radius
short bone
carpals, tarsals
irregular bone
vertebrae, ossicles of the ear
sesamoid bone
patella
sutural/wormian bone
between flat bones of the skull
epiphysis
end of a developing bone
metaphysis
narrow portion of a long bone between epiphysis and diaphysis
diaphysis
shaft of long bone
periosteum
fibrous vascular membrane that forms the covering of bones except at their joint surfaces
compact bone
dense, hard layer of bone tissue
medullary canal
narrow space or cavity throughout the length of the diaphysis
endosteum
tough, connective tissue membrane lining the medullary canal and containing the bone marrow
cancellous/spongey bone
reticular network that makes up most of the volume of bone
condyle
rounded projection that enters into the formation of a joint, articulation
crest
ridge on a bone
fissure
slitlike opening between two bones
foramen
opening in the bone for blood vessels, ligaments, and nerves
fossa
shallow depression in or on a bone
head
rounded end of a bone
meatus
tubelike passage or canal
process
enlargement or protrusion of a bone
sinus
air cavity within certain bones
spine
pointed, sharp, slender process
sulcus
groove, furrow, depression, or fissure
trochanter
either of the two bone projections below the neck of the femur
tubercle
small, rounded process
tuberosity
large, rounded process
epiphyseal plate
hyaline cartilage plate in the metaphysis at the end of a long bone
Joint
Articulation, a place where two or more bones connect
Synarthrosis (fibrous)
Does not permit movement, bones are in close contact with each other but there is no joint cavity
Amphiarthrosis (cartilaginous)
Permits very slight movement
Diarthrosis (synovial)
Allows free movement in a variety of directions. synovial membrane lines the joint and produces synovial fluid, which lubricates the joint
Flexion
Bending a limb
Extension
Straightening a flexed limb
circumduction
Moving a body part in a circular motion
Abduction
Moving a body part away from the middle
Adduction
Moving a body part toward the middle
Protraction
Moving a body part forward
Retraction
Moving a body part backward
Rotation
Moving a body part around a central axis
Dorsiflexion
Bending a body part backward
Pronation
Lying prone, also turning the palm downward
Supination
Lying supine, turning the palm or foot upward
Eversion
Turning outward
Inversion
Turning inward
Closed fracture
Bone breaks but skin remains intact (simple fracture)
Open fracture
Bone beaks and protrudes through the skin (compound fracture)
Complete fracture
Fracture involves the entire width of the bone
Greenstick fracture
Bone fragments are still partially joined (incomplete fracture)
Communicated fracture
Bone fragments into many pieces
Impacted fracture
The two ends of the bone are forced together (buckle fracture)
Oblique fracture
Fracture occurs diagonal to the bones axis
Transverse fracture
Fracture occurs at a right angle to the bones axis
Linear fracture
Fracture occurs parallel to the bones axis
Displaced fracture
Broken ends of bones move out of correct anatomical alignment (unstable fracture)
Nondisplaced frature
Broken ends of bones remain aligned (stable fracture)
Avulsion fracture
A fragment of bone is separated from the rest of the bone, may cause displacmenet of surrounding tissues
stress fracture
Caused by small repetitive forces on the bone
Spiral fracture
Fracture spirals around the bone, occurs as the result of a twisting force
Depression fracture
Bone is forced inward
Pathologic fracture
Caused by a disease that weakens the bone
Compression fracture
Bone is crushed
