100
our spine is made up of individual bones called
vertebrae
100
Inside the center of a long bone is this hollowed out cavity called... that has an inner lining called ...
(Let's make this a TRIPLE!!!)
100 = medullary cavity
300 = endosteum
100
the longest leg bone
femur
100
scientific name for the jaw
(DAILY DOUBLE) - top lip bones
mandible
maxilla
100
breastbone -- middle of your chest
sternum
200
pins, rods, metal plates are all examples of what type of fracture treatment
internal fixation
200
Flat bones examples (list 2)
cranial bones, scapula, sternum
200
Example of an irregular bone (DAILY DOUBLE)
vertebrae, sacrum, coccyx, and certain skull bones
200
The fracture that breaks through the skin
compound/open
200
kneecap
patella
300
The protective layer at the outside of the bone
periosteum
300
list the bones of the feet
tarsals, metatarsals, phalanges
300
Bones are connected to one another by
(DAILY DOUBLE)
ligaments
300
minerals in bone
calcium and phosphorus
300
what is traction
pulling force to hold/move bones back into place/proper alignment
400
list the types of bone cells and their jobs (looking for 3)
osteoblast - builders
osteoclasts - remodel
osteocyte - mature builder
400
list the two types of bone marrow, their jobs and locations
yellow, medullary cavity, store fat
red, epiphysis/in spongy bone, hemopoiesis/new blood cells
400
list the different types of ribs and how many there are of each
7 true ribs
3 false
2 floating
400
list 4 of the different types and fractures and explain what each is
greenstick - kids, partial break
oblique - diagonal
transverse - straight across
spiral - spiral, need 2 x-rays
compression - pushed in on either side
depressed - flat bone pushed in
comminuted - shattered, many pieces
400
What two things are connected by a tendon?
bone and muscle
500
A patient arrives at the emergency department with a broken lower leg after a fall.
The doctor first manually realigns the bone without making any incision to improve its position and reduce pain.
However, imaging shows the fracture is unstable and will not stay aligned. The patient is then taken to surgery, where the surgeon makes an incision to access the bone and secures it using metal plates and screws placed inside the body.
- First step: Closed reduction
didn't work so...
- Final treatment: Open reduction + internal fixation
500
List all the cranial & facial bones. Be sure to indicate how many...
parietal 2
temporal 2
frontal
occipital
sphenoid
ethmoid
nasal bones 5
zygomatic 2
maxilla 2
mandible
palatine 2
500
The minor jobs of the skeletal system
What is making blood cells and store fat cells, calcium, and other minerals?
500
open reduction - surgically reducing fracture
internal fixation - securing the reduced bones internally through methods that will remain in the body (screws, plates, etc.)
500
explain bone formation in an embryo (how it starts, changes, key time frames, key terms)
start as cartilage model
at 8 weeks ossification starts
not complete bones at birth - fontanels
takes 18 months for fontanels to solidify
