List the major components to the skeletal system - (ANSWER)- Bones of the skeleton
- cartilages, ligaments, and other connective tissue
List and briefly describe the major functions of the skeletal system. - (ANSWER)- support
- storage of minerals and lipids
- blood cell production
- protection
-leverage
List the major components of osseous tissue. - (ANSWER)supporting connective tissue
outer lining(periosteum)
inner lining (endosteum)
List and briefly describe 4 types of cells in mature bone. - (ANSWER)osteoblasts,- immature
cells that produce new bone matrix during ossification; osteoblasts surronded by bone matrix
becomes osteocytes
osteoclasts- absorb and remove bone matrix; important in homeostatsis; secrete acids and protein
digesting enzymes
osteocytes- mature bone cells that dont divide; help repair damaged bone
osteogenic- Mesenchymal cells that divide to produce osteoblasts, assits in fracture repair
, Identify the categories used for classifying a bone according to shape. - (ANSWER)a) Sutural
bones (wormian bones)
b) Irregular bones
c) Short bones
d) Flat bones
e) Long bones
f) Sesamoid bones
Define bone markings - (ANSWER)-Projections, where muscles, tendons and ligaments attach;
at articulations with other bones
- Openings and depressions, for passage of blood vessles and nerves
Describe the functional and structural differences associated with compact and spongy bone -
(ANSWER)- compact bone tissue forms the outer layer of all bones and are made of osteons
- spongy bone or cancellous bone forms the inner layer of all bones and are made of trabeculae
Label the organization of compact and spongy bone on Figure 6.3, 6.7, 6.8 - (ANSWER)
Define Periosteum and Endosteum - (ANSWER)- Endosteum covers the inside of bones and
surronds the meduallry cavity
- Periosteum covers outside of bones
. Define the differences between Ossification, Osteogenesis and Calcification - (ANSWER)-
Ossification ( Osteogensis)= bone formation; 2 forms which are Enchondronal and
Intramemebranous ossification
- Calcification= deposition of calicum salts, occurs during ossification
