WEEK 7 Flashcards
alterations in mobility ATI + notes from class
mobility
ability for free movement
immobility
not able to move or motionless
what does the musculoskeletal system include
bones
connective tissue
muscles
joints
The functions of the musculoskeletal system include the following. (6 things)
Maintaining body form and shape
Providing support and mobility
Protecting soft organs
Maintaining hemostasis of calcium, phosphate, and magnesium levels within the body
Formation of blood cells through stem cells in the red or yellow bone marrow
Reserving energy through triglyceride storage in the yellow marrow
how many bones are in the adult human skeleton
206
what is the adult human skeleton system divided into
axial section and appendicular section
what is the axial section of the skeleton composed of
bones along the axis of the body
skull
sternum
ribs
spine
what is the appendicular section of the skeleton composed of
bones of the appendages
clavicle
scapula
humerus
ulna
radius
pelvis
carpals
metacarpals
phalanges
femur
patella
tibia
fibula
tarsals
metatarsals
phalanges
bones are classified based off what
according to their shape
long bones
Long bones, such as the humerus, radius, tibia, and femur, are in the appendicular skeleton. Functionally, the long bones function as levers in mobility
what are long bones usually composed of
diaphysis and epiphysis
diaphysis
Long, cylinder shaped shaft of a bone.
epiphysis
Irregularly shaped ends of the bone.
what is within the shaft of the diaphysis
the medullary cavity, which contains red and yellow bone marrow
The bone marrow in infants is primarily
red
Located at each end of the long bones are the
epiphyses
proximal
closest to center (for mobility that would be torso)
distal
Furthest away from the center; for mobility, this would be away from the torso.
hard part of bone that covers bone structure
periosteum
Short bones include
the carpal bones in the hands, as well as the tarsal bones located in the feet
Short bones are small with a shape like
a cube
Flat bones
bones of the skill, ribs, and scapula (found in the axial skeleton)
Functionally, the flat bones provide
protection for the soft organs
think: skull (brain)
ribs (lungs)
etc
tendons
Connective tissue that connects muscles to bones.
