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 |
