| Term | Definition |
|---|---|
| Structures in a bone slide | Osteon, central canal, canaliculi, lamellae, lacunae, and osteocytes |
| Osteon | Smallest unit of bone |
| Central canal | Contains arteries, veins, and nerves |
| Canaliculi | Little red lines sending nutrients and waste |
| Lamellae | Concentric rings |
| Lacunae | Small space, containing an osteocyte |
| Osteocytes | Red blobs throughout the osteon |
| Structures in a cartilage slide | Lacunae, chondrocytes, and matrix |
| Lacunae | small space, containing a chondrocyte |
| Chondrocytes | Dark blobs in lacunae |
| Matrix | Narrow space surrounding individual cells |
| Structures on a long bone | Diaphysis, epiphysis, epiphyseal line (metaphysis), spongy bone, compact bone, periosteum, endosteum, medullary cavity, and articular cartilage |
