6.4 Bone Structure Flashcards
dense, outer layer of bone; smooth and solid
Compact bone
honeycomb of flat pieces of bone deep to compact
-filled with red and yellow marrow
Spongy bone (trabeculae)
What cartilage covers articular (joint) surfaces?
Hyaline cartilage
elongated shaft of long bone
Diaphysis
central cavity of long bone
-contains yellow or red marrow
Medullary cavity
the end of the long bone, attached to the shaft
Epiphysis
between the diaphysis and each epiphysis of an adult long bone
-a physical division
Epiphyseal line
a disc of hyaline cartilage that grows during childhood to lengthen bone
Epiphyseal plate
double-layered connective tissue that covers and nourishes the bone
Periosteum
dense irregular connective tissue
Outer fibrous layer
next to the bone surface; contains osteogenic cells
Osteogenic layer
stem cells
Osteogenic cells
connective tissue membrane covering internal bone surfaces
- Lines canals that pass through compact bone
- Covers trabeculae of spongy bone
Endosteum
red marrow
Hematopoietic tissue
secrete osteoid (unmineralized bone matrix) composed of collagen and calcium binding proteins
Osteoblasts
