- WHat are some functions of the skeleton?
-
1)dictate body shape
2)provide for Calcium storage & release.
3)provide for hematopoesis
4)fat storage (yellow bone marrow)
5)provides resonance to the voice (pneumatic bones) - What are the 3 parts of the skeleton?
-
Axial-skeleton (skull,vertebral column,ribs and sternum)
Appendicular-limb bones
Accessory- heterotopic skeleton - What are some characteristics of bone?
- Highly vascularized and very dynamic form of connective tissue.
- How does bone occur?
- As compact bone (cortex) & cancellous bone (medullary cavity)
- What is bone composed of ?
- ground substance (allows significant accumulation of salt deposits) 60-70% of bone's weight
- What is the principal crystalline component in bone?
-
hydroxyapatite- a form of calcium phosphate
85% of the inorganic components of bone - How are bones classified?
- long, short, flat and irregular
- What is the diploe?
- space representing the marrow cavity of a flat bone
- What are the general parts of the long bone?
-
articulating surface
epiphysis-
physis- growth plate
metaphysis
diaphysis -
What are the articular & non articular surfaces of long bone capped with?
What is the medullary cavity lined with? -
articular-hyaline cartilage
non-articular-periosteum
endosteum - Where is the nutrient foramina located in the humerus, radius, Ulna, femur, Tibia and fibula
-
Humerus-midcaudal diaphysis
Radius-caudally at junction of proximal & middle thirds of bone
Ulna-cranially at distal extent of radial notch
Femur- caudally at junction of proximal and middle thirds
