Parts of inner bone and skull

Bone matrix

nonliving structual part of bone outside of the lacunae

Red bone marrow

Located in the spongy bone makes red blood cells

nutrient artery

artery in the diphysis

central canal

carries blood vessels and nerves found at center of bone

distal epiphysis

end of the bone located away from midline of body

proximal epiphysis

end of the bone located near the midline of the body

Metaphysis

growth zone

compact bone

hard bone tissue inside the outer layer (periosteum)

spongy bone

has red bone marrow makes cells lighter

medullary cavity

hollow are in shaft that contains yellow bone marrow

epiphyseal line

in the spongy tissue is a growth point

concentric lamellae

matrix around the center canal

bone makers

osteoblast

bone destroyer

osteoclast

bone cell

osteocyte

lacunae

outer coverage of the osetocyte the "home" of the cell

periosteum

protection on outside of bone proper connective tissue

diphysis

shaft of a long bone

yellow bone marrow function

stores fat

canaliculi

tiny canals connecting lacunae

Articular cartilage

top of bone where they come together
