Question | Answer |
---|---|
What tissues are bones made out of? | Compact and spongy osseus tissue, connective tissue, adipose tissue, and cartilage. Bones also have blood vessels and nerves |
Long Bones | longer than they are wide. thick compact bone exterior |
Short bones | equal in length thick inferior of spongy bone covered by veneer of compact bone |
Flat bones | flat and may be curved. Thin spongy bone covered in thin veneer of compact bone |
Irregular Bones | Dont fit into categories |
Sesamoid Bones | small bones that develop in the tendons for protection against wear and tear |
Epiphysis | proximal and distal ends of the bones |
Diaphysis | shaft |
What forms the exterior of long bones and most of diaphysis? | Compact bone |
What layer lines the interior of the diaphysis? | spongy bone |
metaphyses | areas of adult bone where the epiphysis and diaphysis join |
Epiphyseal plate | metaphyses contain a layer of hyaline cartilage |
Articular cartilage | composed of hyaline covers both epiphysis |
Periosteum | bone's exterior is covered with tough connective tissue membrane |
medullary cavity | hollow center of the bony diaphysis |
What lines the medullary cavity? | Endosteum |
The endosteum lines what as well? | spongy bone of the epiphysis |
What do both periosteum and endosteum contain? | Osteoblasts and osteoclasts |
Yellow Marrow | fat substance found between medullary cavity |
red marrow | found within cavities of spongy bone and produce blood cells |
nutrient artery | large arety that enters compact bone near the middle of diaphysis |
Where does the nutrient artery senf blood | branches to the proximal and distal portions which supply blood to inner layer of compact bone, spongy bone, adn red marrow |
Nutrient Foramen | is a foramen through which the nutrient artery enters. |
Compact (cortical) bone | composed of repeating units of osteons, with each unit having a central (Haversian) canal running longitudinally |
periosteum | |
What do central canals contain? | contains blood vessels, lymphatic vessels, and nerves that serve compact bone tissue. |
