classification of bone Flashcards
Longer than wide. range from very large femur to small phalangeal bones
long bone
complex shape with notches and processes.
examples are vertebrae
irregular bone
similar length and width and roughly cube-shaped.
examples are carpals and tarsals
short bone
Develop inside tendons, small and flat bones
sesamoid bone
protect underlying structures. Large surface area for tendon and ligament attachments.
Thin like a plat*
examples are cranila bones, ribs and scapula
flat bone
composed of hyaline cartilage
covers portion of each epiphysis involved in joint
Articular cartilage
narrow zone between each epiphysis and the diaphysis. Also called metaphysis or epiphyseal plate when cartilage is present
Spongy bone
contains yellow bone marrow. lined with spongy bone
Medullary cavity
connective tissue membrane. lines medullary cavity
Endosteum
Found in medullary cavity. Gets its yellow color from an abundance of flat cells
Yellow bone marrow
cavities of spongy bone house red bone marrow
sites of Hematopoiesis*
Epiphyseal disks
thin connective tissue covering surface of long bone
Periosteum
axial end of the long bone. composed primarily of spongy bone with thin covering of compact bone
Proximal epiphysis
tube-shape shaft of long bone*
composed of both compact bone and spongy bone
Diaphysis
distal end of the long bone same composition as proximal epiphysis.
Distal epiphysis
