| Compact Bone | Looks smooth and homogeneous |
| Spongy Bone | Composed of small trabeculae of bone and lots of open space |
| Wormian | tiny bones between the sutures of the skull bones |
| Epiphysis | Ends of long bones (remember e is curved like end of long bone) |
| Diaphysis | Shaft of long bone (remember d has a shaft) |
| Periosteum | Outer fibrous membrane covering of a bone |
| Endosteum | Inner lining of the shaft |
| Epiphyseal plate | Thin area of hyaline cartilage |
| Epiphyseal lines | -Remnants of Epiphyseal plate -made of bone |
| Medullary cavity | Hollow center of a long bone |
| Red bone marrow | Makes blood cells |
| Articular cartilage | -Also called hyaline cartilage -covers parts of bones that form joints, such as the Epiphysis |
| Markings of scapula | 1. acromion process (tip of shoulder) 2. spine of scapula 3. glenoid fossa (grove) 4. Coracoid process (under acromion, beak) |
| Markings of Humerus | 1. head of the humerus (looks like a ball) 2. proximal vs. distal end 3. olecranon fossa (on bottom posterior) (anterior has 3 ball parts on bottom) |
| Markings of Radius | radius is lateral 1. head of radius (disk shaped head) 2. proximal vs. distal ends (small to big) 3. styloid process (lateral on big distal end) |
| Markings of Ulna | 1. olecranon process (ball on posterior side) 2. styloid process (medial, little piece on distal end that hangs down) 3. proximal vs distal ends (proximal-socket wrench) |

| Pubis | pubic symphysis (joint between two pubis bones) |
| acetabulum | socket where the head of femur articulates |
| Markings of Femur | 1. head and neck of femur 2. greater and lesser trochanter (top of cape, bottom of cape) 3. medial and lateral condyles (medial on same side as head) 4. proximal vs distal ends |
| Markings of Tibia | 1. tibial tuberosity (anterior, big bump on front) 2. medial malleolus (protruding edge) 3. proximal vs distal ends (distal has sharp part) |
