anatomy ch. 5
where bones meet
articulation joints
greenstick fracture
bending and incomplete break of a bone; most often seen in children
cartilaginous joints (ellipsoid)
between hands and fingers
comminuted fracture
bone breaks into many fragments
depressed fracture
broken bone portion is pressed inward
Small canals that connect osteocytes in their lacunae to the central canal are known as
canaliculi
bones in wrist
carpals (8)
examples of short bones
carpals and tarsals
gliding joints
carpals and tarsals
pectoral girdle includes what 2 bones
clavicle and scapula
periosteum
connective tissue membrane surrounding diaphysis
articular cartilage
contains hyaline cartilage; smooth, slippery surface to decrease frictions between other bones
The suture connecting the frontal bone and parietal bones is the:
coronal
freely movable joints
diarthroses - synovial
hinge joint
elbow and knee
lengthwise growth
epiphyseal plate - primary/endochondral
the crista galli is located on what bone
ethmoid
forms cells
osteoblasts
break down cells
osteoclasts
what makes up the hard palate
palatine and maxilla
pivot joint
palm up or down knodding
What forms the appendicular skeleton?
pectoral girdle & arms, pelvic girdle & legs
suture connecting two parietal bones
sagittal suture
ball and socket joint
shoulder and hip
examples of flat bones
skull & sternum
What forms the axial skeleton?
skull, vertebral column, thoracic cage
lacunae
small cavities that contain osteocytes
sella turcica is located in what bone
sphenoid
cancellous is what type of bone
spongy
suture connecting temporal and parietal
squamous
Functions of the skeletal system
support, protection, movement, stores minerals, hematopoiesis
immovable joints
synarthroses - fibrous
bones in ankle
tarsals (7)
saddle joint
thumb
spiral fracture
twisting of bone
examples of irregular bones
vertebrae and hip bones
sharpey fibers
"needles" holding periosteum
steps of bone healing
1. blody clot (hematoma) 2. cartillage callus 3. bony callus 4. remodeling
how many bones in the body
206
feature in coxal bone where head of femur articulates
acetabulum
scapula has what process
acromion process (shoulder)
slightly movable joints
amphiarthroses - cartilage
long bones :
femur, tibia, fibula, humerus, radius, ulna
what hole goes through the occipital bone
foramen magnum
appositional (intramembranous)
growth in diameter
What bone does not articulate with any other bone?
hyoid bone
pelvis contains what 3
ilium, ishium, & pubic
The suture connecting the occipital bone and the parietal bones is the:
lambdoidal
lamella
layer of matrix
osteocyte
mature bone cell
