2. Bone Tissue
• Compact Bone: Contains haversian canals
surrounded by concentric rings of matrix that
contains osteocytes
3. Bone Tissue
• Compact Bone: Contains haversian canals
surrounded by concentric rings of matrix that
contains osteocytes
• Spongy Bone: Less dense than compact bone.
Contains thin columns of bone tissue
surrounded by small, irregular cavities. The
cavities are filled with red bone marrow,
which forms red and white blood cells.
4. Bone Shapes
Shape Description Example
Long Longer than it is wide Femur
Short Approximately cube shaped Carpals
Flat Thin, usually curved Cranial bones
Irregular Do not fit any of the Vertebrae
categories above

7. Parts of a long bone
1. Diaphysis: cylindrical main portion of a bone.
Made of compact bone
2. Epiphyses: Enlarged ends of the bone.
