Patella
Contains spongy bone in adults
Epiphysis
Made of compact bone
Diaphysis
Site of blood cell formation
Epiphysis and spongy bone
Major submembranous site of osteoclasts
Endosteum
Scientific term for bone shaft
Diaphysis
Contains fat in adult bones
Medullary cavity
Growth plate remnant
Epiphyseal line
Major submembranous site of osteoblasts
Periosteum
Difference between compact and spongy bone
Compact - dense, strong, yellow marrow
Spongy - Ends of bones red marrow, blood made (yellow in adults that can convert to red to make blood)
Function of the periosteum
Fibrous membrane covering attached by fibers
Enter into bone allowing nerves, blood/lymphatic vessels top pass through it
Route taken by nutrients through a bone, starting with periosteum and ending with an osteocyte in a lacuna
Periosteum - perforating canals - central canals - caliculus - lacunae
Layers of bony matrix around a central canal
Concentric lamellae
Site of osteocytes
Lacunae
Longitudinal canal carrying blood vessels, lymphatics, and nerves
Central canal
Minute canals connecting osteocytes of an osteon
Caliculi
Inorganic salts deposited in organic ground substance
Matrix
Function of the organic matrix in bone
Gives flexibility and strength
Important organic bone components
Collagen fibers and osteocytes
Calcium salts are the bulk of inorganic components in the bone. What is the function of the calcium salts
Gives bone hardness and compressional strength
Baking removes _________ from bone
water
Soaking bone in acid removes
calcium salts
Events occuring on the epiphyseal and diaphyseal faces of the epiphyseal plate
Epiphyseal face
Cartilage cells resting, inactive, below rapid of reproduction cells
Events occuring on the epiphyseal and diaphyseal faces of the epiphyseal plate
Diaphyseal face
Chondrocytes are dying, matrix calcifying, cartilage being replaced by bone
Supports external ear
Elastic
Between the vertebrae
Fibrocartilage
Forms the walls of the voice box (larynx)
Elastic
The epiglottis
Elastic
Articular cartilages
Hyaline
Meniscus in a knee joint
Fibrocartilage
Connects the ribs to the sternum
Hyaline
Most effective at resisting compression
Fibrocartilage
Most springy and flexible
Elastic
Most abundant
Hyaline
