Chapter 3: Medical Terminology - The Skeletal System Flashcards
consists of bones, bone marrow, cartilage, joints, ligaments, synovial membrane, synovial fluid, and bursae
skeletal system
cells break down old or damaged bone
osteoclast
cells help rebuild the bone
osteblast
repairs minor damage to the skeletal system
ossification
act as the framework of the body, protect the internal organs, and store calcium
bone
is tough, fibrous tissue that forms the outermost covering of bone
periosteum
word root: means bone
oste
aka cortical bone. is dense, hard, and very strong bone that forms the protective outer layer of bones accounts for more than 75% of the bodys bone matter
compact bone
aka cancellous one. porous (sponge-like) which makes it lighter and weaker than compact bone.
red bone marrow is located within and commonly found in the ends and inner portions of long bones as well as the pelvic bones
spongy bone
femur and hummerus
long bones
include bones of the wrist and ankle. they are cube-shaped and made up spongy bone covered with layer of compact bone
short bones
true or false: bones with a large percentage of spongy one are weaker and more susceptible to fractures
true
the central cavity located in the shaft of long bones where it is surrounded by compact bone
red and yellow bone marrow are stored
medullary cavity
pertaining to the inner section
medullary
the tissue that lines the medullary cavity
endosteum
prefix: means within
end-
located within the spongy bone a hematopoietic tissue that manufactures red blood cells, hemoglobin, white blood cells, and thrombocytes
red bone marrow
pertaining to the formation of blood cells
hematopoietic
combining form: means blood
hemat/o
suffix: means pertaining to formation
-poietic
functions as a fat storage area. composed chiefly of fat cells and is located in the medullary cavity of long bones
yellow bone marrow
true or false: most bone marrow is red from birth through early adolescence, after which about half is gradually replaced by yellow bone marrow
true
the smooth rubbery blue-white connective tissue that acts as a shock absorber between bones
cartilage
true or false: cartilage is more elastic than bone, also makes up the flexible parts of the skeleton such as outer ear and tip of the nose
true
