1 Compact Bone Diaphysis

2 DIAPHYSIS Shaft/midsection of a long bone consisting of mostly compact/hard bone. Compact bone is relatively solid and dense. Has few spaces and is also found in the outer layer of most other types of bones.

3 Epiphysis Compact Bone Spongy Bone Diaphysis Proximal Epiphysis Distal

4 EPIPHYSIS (Proximal & Distal)
Made up of cancellous or spongy bone. Cancellous/Spongy bone has an irregular latticework structure (like honeycomb) where there are many spaces. It is also found in short, flat and irregular bones. Red marrow is stored there, blood cell production occurs here.

5 Compact Bone Epiphysis
Articular Cartilage Compact Bone Proximal Epiphysis Spongy Bone Diaphysis Epiphysis Distal Epiphysis

6 ARTICULAR CARTILAGE Thin layer covers the ends of the bone where they articulate with other bones to form joints. Main functions are to reduce friction between the bones and absorb shock. Red marrow is stored there, blood cell production occurs here.

Articular Cartilage Compact Bone Proximal Epiphysis Spongy Bone Diaphysis Periosteum Epiphysis Distal Epiphysis

8 PERIOSTEUM The area of the bone not covered by cartilage but instead by a thin, shiny white membrane. This forms the outer lining of the bone and is important for bone growth, repair, nutrition and attachment of ligaments and tendons.

9 Medullary (Marrow) Cavity

10 MEDULLARY (MARROW) CAVITY
Space within the diaphysis where yellow bone marrow is stored. There is a small opening in the diaphysis called the nutrient foramen. Blood vessels pass through here, enter the medullary cavity and provide the marrow and compact bone with blood and nutrients.
