Compact Bone |
Type of ossecus tissue appears smooth & homogenecus |
|
Spongy Bone |
Type of ossecus tissue composed of a network of bone tissue w/ a great deal of open space in between. |
|
Long Bone Anatomy- Proximal Epiphysis |
The end of a long bone towards the axis, outer surface is padded w/ articular cartilage for the formation of joints, composed of a thin layer of compact bone surrounding sponge bone |
|
Distal Epiphysis
|
The end of a long bone away from the midline
|
|
Long bone Anatomy- Articular Cartilage |
Cover the bone ends at movable joints, epiphysel surface. Composed of hyaline cartilage to reduce friction. |
|
Long Bone Anatomy-Diaphysis |
Shaft of long bone which is composed of compact bone, contains an open space called a medullary cavity. |
|
Periosteum
|
Double layer of protective membrane covering the outer surface of bone. Outer fibrous layer is dense connective tissue; inner osteogenic layer contains osteoblasts, osteoclasts, and osteocytes.
|
|
|
Osteoblasts |
(Bone forming Cells) |
|
|
Osteoclasts |
(Bone destroying cells) |
|
Epiphyseal Line
|
Indicates no further bone growth will occur after all cartilage has been replaced with bone.
|
|
Medullar Cavity
|
The central cavity of the shaft that is storage region for adipose tissue or blood cell formation
|
|
Yellow Bone Marrow
|
Adipose tissue stored in medullar cavity
|
|
Red Bone Marrow
|
Site of hematopoiesis, red blood cell formation; occupies interior of the epiphysis b/w trabeculae of spongy bone.
|
|
Microscopic Structures of Bone-Osteon |
A central canal & all the concentrate llamellae surrounding it; AKA Haversion system |
|
Lamellae
|
Layers of bony matrix around a central canal
|
|
Haversion Canal
|
Central canal, longitudanal canal in the bone that carries blood vessels, nerves, & lymphatic vessels through bone matrix center of osteon
|
|
Microscopic Structures of Bone-Osteocytes
|
Mature bone cells found within lacunae (chambers) which are arranged in concentric circles called concentric lamellae.
|
|
Microscopic Structures of Bone-Lacunae |
Chambers; arranged in concerntric circles around concentric Lamellae. |
