pica
where is red bone marrow found?
flat bones and the epiphyses of long bones
perforating collagen fiber bundes in bone
sharpey’s canals
membrane of vasculature that wraps around most bone
periosteum
where do muscles attach to bone
periosteum
membrane lining inner surface of a bony wall
endosteum
which cell within bones has a separate origin from other bone cells
osteoclasts come from white blood cells
rickets indicates a lack of
vitamin d
tissues that give rise to blood cells
hemopoietic tissue
bone development takes place within bone form
intramembranous bone formation
where is intramembraneous bone formation seen
primarily in the roofing bones of the skull
most common type of bone growth
endochondral bone formation
what type of bones have secondary ossification centers
only those that are especially long
growing in thickness/ diameter of a bone
appositional growth
what happens to the size of the medullary cavity during appositional growth?
gets larger which shows a lot of osteoclast activity
blood clot
hematoma
what forms from a hematoma after a bone fracture
internal and external callus made offibrocartilage
bone fractures into 3+ pieces
comminuted fracture
bone is crushed, common in porous bones
compression (fracture)
bone breaks in response to twisting
spiral fracture
epiphyses and diaphyses separate along the epiphyseal plate, disruption the growth center
epiphyseal fracture
broken bone is pressed inward, common of skill
depressed fracture
bone breaks incompletely
greenstick fracture
inorganic component of bone
calcium hydroyapetite
bone marrow stops making blood cells leading to anemia
aplastic anemia
another name for wormian bones
cosinca
sutures don’t form properly and an accumulation of fluid pushes bones apart
hydrocephaly
why do cervical vertebrae have bifid spinous processes?
significant musculature is required to keep the head upright
what is meant by demifacet?
shared between two vertebrae
how do ribs and vertebrae connect?
head to body and tubercle to transverse process
another term for the head of the rib
capitulum
differentiate between the articular processes of lumbar and thoracic articular facets
thoracic are anterior or posterior while lumbar are medial and lateral
when do fontanelles close?
14-24 months
function of anterior and posterior longitudinal ligaments
preventing hyperextension and hyperflexion respectively
bony joints
synostoses (seperation between two joints ossify)
example of synostosis
metopic suture
suture with teeth that come together at a jagged line
serrated suture
suture where overlap is seen
lap suture
example of lap suture
squamous suture
suture with relatively flat edges
plane suture
examples of plane sutures
intermaxillary, interpalatine, and palomaxillal
sheet-like flat ligament seen in other pieces of bone
interosseous ligament
bones with interosseous ligaments
radius and ulna/ tibia and fibula
binds teeth to the alveolus
peridontal ligament (gomphosis)
bone-like structure within teeth
dentin
components of the capsule of synovial joints
outer collagenous fibers and inner synovial membrane
surrounds the bone and continues onto the fibrous layer of the capsule
periosteum
fibrocartilage disks sitting between bones
menisci
overuse of muscle leads to inflamed tendon sheath
tendonitis
inflammation of small sacs in complex joints that are filled with synovial fluid for cushion
bursitis
ligament of the glenohumeral joint with three pieces
glenohumeral ligaments (superior, medial, and inferior)
helps with stability of the shoulder joint
glenoid labrum
which meniscus of the knee is more closed
the lateral meniscus
rotator cuff muscles
supraspinatus, infraspinatus, subscapularis, and teres minor
annular ligament is pulled from the head of the radius
pulled elbow
