Bone Tissue

Osteoblasts – bone forming cells

Osteocytes – The BONE CELLS

Osteoclasts – bone reabsorbing cells

Two Types of Bone Tissue

Compact Bone and Spongy Bone

Bone Development & Growth

Two Categories of Bone Development

1.Intramembranous (Direct) – forms spongy bone and eventually may form compact bone from embryonic fibrous membrane

2.Endochondral - bone forms from cartilage; forms skull & flatbones

Before week 8 of fetal life, the human skeleton is all fibrous membrane & hyaline cartilage
