clavicle - Answers -✔✔ collarbone
functions of the skeletal system - Answers -✔✔ support, protection, movement,storage,
hematopoiesis
four major types of bones - Answers -✔✔ long bones, short bones, flat bones, irregular
bones
hemopoiesis - Answers -✔✔ the process of blood cell formation carried out in the red
bone marrow
red bone marrow - Answers -✔✔ is soft connective tissue inside the hard walls of some
bones that produce both red and white blood cell.
structure of long bones - Answers -✔✔ diaphysis, medullary cavity, epiphyses, articular
cartilage, periosteum, endosteum
compact bone - Answers -✔✔ the outer layer of bone is hard and dense. Does not
contain a network of open spaces. Instead, the extracellular matrix is organized into
numerous structral units called osteons or haversian systems.
diaphysis - Answers -✔✔ or shaft - hollow tube made of hard, compact bone, hence a
rigid and strong structure light enough in weight to permit easy movement.
medullary cavity - Answers -✔✔ the hollow area inside the diaphysis of a bone ;
contains soft yellow bone marrow , an inactive, fatty form of marrow found in the adult
skeleton.
epiphyses - Answers -✔✔ or the end of a bone - red bone marrow fills in small spaces
in the spongy bone composing the epiphyses; some yellow marrow may appear as a
persons age.
articular cartilage - Answers -✔✔ a thing layer of cartilage covering each epiphyses;
functions like a small rubber cushion would if it were placed over the ends of bone
where they form a joint.
periosteum - Answers -✔✔ a string membrane of dense fibrous tissue covering a long
bone everywhere except at joint surfaces, where it is covered by articular cartilage.
, endosteum - Answers -✔✔ a thin membrane that lines the medullary cavity.
cancellous bone - Answers -✔✔ spongy bone contains many spaces. The cavities are
filled with red or yellow marrow.
trabeculae - Answers -✔✔ beams that form the lattice of spongy bone.
osteon - Answers -✔✔ or haversian system- structural unit of compact bone tissue
made up of concentric layers
(lamellae) of hard bone matrix and bonecells (osteocytes).
concentric lamella - Answers -✔✔ ring of calcified matrix surrounding the haversian
canal.
central canal - Answers -✔✔ or haversian canal - contains blood vessels; any tubelike
passage a the center of a structure, such as the canal running though the center of the
spinal cord or through the center of each osteon in compact bone.
lacunae - Answers -✔✔ space or cavity; osteocytes lie between the hard layers of the
lamellae in little spaces.
canaliculi - Answers -✔✔ tiny passageways, or canals that connect the lucunae with
one another and with the central canal in each osteon.
cartilage cells - Answers -✔✔ chondrocytes
osteoblasts - Answers -✔✔ bone-forming cells; form new bone
osteoclasts - Answers -✔✔ none-reabsorbing cells; dissolve existing bone tissue
endochondral ossification - Answers -✔✔ meaning " formed in cartilage"
epiphyseal plate - Answers -✔✔ the cartilage plate that is between the epiphysis and
the diaphysis and allows growth to occur; sometimes referred to as a growth plate.
epiphyseal line - Answers -✔✔ faint line remaining after the epiphysis fuses with the
diaphysis.
fontanels - Answers -✔✔ the soft spots, on a newborn baby's skull are areas of fibrous
membrane that have not yet fully ossified.
Human skeletons two divisions - Answers -✔✔ axial skeleton and appendicular
skeleton
