2 most important minerals stored in bones
phosphorus and calcium
vertebrae bones
irregular
ankle bones
short
hip/coxal bones
irregular
short bone shape
cubed
red bone marrow function
makes red blood cells
yellow bone marrow function
stores fat
what does an epiphyseal plate conclude about a bone?
it's still growing
what activities determine where bone matrix is to be remodeled?
gravity and muscles
in an embryo, what is the forerunner of long bones?
highline cartilage
canal that runs through core of each osteon contains
blood vessels and nerves
example of both a sesamoid bone and a short bone
patella
what happens when the blood levels of Ca drop below normal?
PTH rises, osteoclast increases
compound fracture
breaks skin
green stick fracture
common in kids, frays bone
comminuted fracture
bone is shattered
what makes up the axial skeleton?
skull , ribs, vertebrae, sternum
unpaired facial bone
vomer
what bone does the foramen magnum pass through
occipital
what makes the hyoid bone unique
not jointed to any other bone
mastoid process is located on the
temporal bone
number of thoracic vertebrae
12
number of lumbar vertebrae
5
what is the atlas
1st cervical vertebrae
order of ribs from superior to inferior
true, false, floating
number of true rib pairs
7
number of floating rib pairs
2
ilium is the major part of the
coxal bone
what is different between a female and male pelvis
greater distance between female ischial spines
2 largest foot bibes
calcaneus, talus
example of cartilaginous joint
symphisus
example of fibrous joints
tibia, fibula
slight movement
amphiarthroses
no movement
synarthrosis
compression fracture
bone is crushed, common in osteoporosis patients
tiny canals/passageways that radiate outward from the central canals to all lacunae; form a transportation system that connects all the bone cells to the nutrient supply through the hard bone matrix
canaliculi
connective tissue fibers, secure the periosteum to the underlying bone
sharpey's fibers
dense and looks smooth and homogeneous
compact bone
composed of small needlike pieces of bone and lots of open space
spongy bone
basin like depression in a bone, serve as an articular surface for joints
fossa
narrow, slit like opening
fissure
4 steps of bone healing
hematoma is formed, break is splinted by fibro cartilage callus, bony callus is formed, bone remodeling occurs
tiny cavities within matrix
lacunae
5 regions of vertebrae column
cervical, thoracic, lumbar, sarcum, coccyx
bone destroying cells
osteoclasts
process of creating new blood cells
hematopoiesis
four distinguishing features of synovial joint
articular cartilage, fibrous articular capsule, joint cavity, reinforcing ligaments
five functions of skeletal system
support, movement, protection, storage, hematopoeisis
support
bones form the internal framework that supports and anchors all soft organs
protection
bones protects soft body organs ex: skull to the brain
movement
skeletal muscles, attatched to bones by tendons, use bones as levers to move the body and its parts
storage
fat is stored in the internal cavities of bones, bone itself serves as a storehouse for minerals
blood cell formation (hematopoesis)
blood cell formation occurs within the marrow cavities of certain bones
bone forming cells
osteoblasts
