periosteum
thick, fibrous membrane that covers the outside of a bone; anchors tendons & ligaments; contains blood vessels, nerves, & lymph vessels
spongy bone
found in the ends of long bones; characterized by irregular spaces filled with red bone marrow that makes blood cells; helps keep bones light in weight
compact bone
dense, hard bone forming the shaft of long bones & the outer layer of other bones
epiphyseal plate
thin band of cartilage that is the growth zone between areas of ossification

Intramembranous ossification timeline
occurs during fetal life
Intramembranous ossification location
mandible, clavicle, and cranial bones ( frontal, parietal, temporal, and occipital)
intamembranous ossification
bone tissue differentiates from fibrous membrane (mesenchyme become osteoblasts)
Intramembranous ossification process
ossification starts in the center of bone, moves towards edges
