long bones
18
19
20
21
contains spongy bone in adults
F, epiphysis
22
made of compact bone
C, diaphysis
23
site of blood cell formation
J, Red Bone Marrow
24
major submembranous site of osteoclasts
D, endosteum & I, periosteum
25
scientific term for bone shaft
C, diaphysis
26
contains fat in adult bones
G, Medullary Cavity
27
growth plate remnant
E, Epiphyseal line
28
major submembranous site of osteoblasts
D, endosteum & I, periosteum
29
What differences between compact and spongy bone can be seen with the naked eye?
compact bone diaphysis looks solid, practically without holes or gaps-

spongy bone is metaphysis and the epiphysis on the other hand are composed of thousands of spicules or trabeculae of bone, interconnected
30
What is the function of the periosteum?
The Periosteum serves as an attachment point for muscles and bones through tendons and ligaments.
31
Trace the route taken by nutrients through the bone, starting with the periosteum and ending with an osteocyte in a lacuna.
The path is: Periosteum, Perforating Canals, Central Canals, Canaliculi, Lancunae, Osteocytes
32
concentric lamellae
layers of bony matrix around a central canal
33
lacunae
site of osteocytes
34
central canal
longitudinal canal carrying blood vessels, lymphatics, nerves
35
canaliculi
minute canals connecting osteocytes of an osteon
36
matrix
inorganic salts deposited in organic ground substances
37

On the photomicrograph of bone on the right (365x), identify all structures maned in the key and bracket an osteon.
A. Canaliculi
B. Concentric Lamellae
C. Lacunae
D. Central canal
E. Matrix
38
What is the function of the organic matrix in bone?
Gives bone flexibility & strength
39
Name the important organic bone components
Collagen fibers, osteocytes
40
Calcium salts form the bulk of the inorganic material in bone. What is the function of the calcium salts?
Gives bone hardness & compressional strength.
41
Baking removes _______________ from bone. Soaking bone in acid removes _________________.
baking removes what from bone? ORGANIC
soaking in acid removes? MINERALS
42
Compare and contrast events occurring on the epiphyseal and diaphyseal faces of the epiphyseal plate?
The cartilage cells at the epiphyseal side are continuing to grow and divide mitotically, while the ones on the diaphyseal side are aging, dying and then osteoblasts move in to form bone.
43
Type of cartilage that supports the external ear
Elastic
44
Type of cartilage between the vertebrae
Fibrocartilage
45
Type of cartilage that forms the walls of the voice box (larynx)
Hyaline
46
Type of cartilage that forms the epiglottis
Elastic
47
Type of cartilage forming the articular cartilages
Hyaline
48
Type of cartilage that forms the meniscus
Fibrocartilage
49
Type of cartilage that connects the ribs to the sternum
Hyaline
50
Type of cartilage thats the most effective at resisting compression
Fibrocartilage
51
The most springy and flexible type of cartilage
Elastic
52
The most abundant type of cartilage
Hyaline
