QUIZ ONE ANATOMY

Function of the skeletal system: Support

• Provide framework for attachment of SOFT tissues and ORGANS

• 1/3 COLLAGEN fibers(organic) 2/3 CALCIUM salts(inorganic)

• Change magnitude and directions of the forces generated by muscular system

• Protect origins by acting as a barrier

• Red Blood Cells, White Blood Cells,platelets are produced in Red Marrow

Functions of the skeletal system: Protection

• RED Blood cells, WHITE Blood Cells, and Platelets are produced in RED Marrow

• Protect ORGANS by acting as a BARRIER 

• ⅓ Collagen fibers(organic) ⅔ calcium salts(inorganic)

  Energy reserves(lipids) stored in YELLOW Marrow(fats)

• Provide a framework for the Attachment of SOFT tissues and ORGANS

• Change in Magnitude and Direction of the forces generated by the MUSCULAR system 

Function of the skeletal system: Movement/ Leverage

• ⅓ Collagen fibers(organic) ⅔ calcium salts(inorganic)

  Energy reserves(lipids) stored in YELLOW Marrow(fats)

• Provide a framework for the Attachment of SOFT tissues and ORGANS

• RED Blood cells, WHITE Blood Cells, and Platelets are produced in RED Marrow 

• Change in Magnitude and Direction of the forces generated by the MUSCULAR system

Choose all TRUE about BONE

• OSSIFICATION- process by which cartilage SLOWLY hardens into bone as a result of MINERALS and CALCIUM

• Controls release of CALCIUM from BONE to BLOOD

• Specialized Connective Tissue- STRONG as STEEL but as LIGHT as ALUMINUM

• RESPONSIBLE for Secreting ACID leading to OSTEOLYSIS

• Bones Grow until the AGE of 17-21

Three types of Bone Cells: Osteocytes

• Secrete the ORGANIC components RESPONSIBLE for BUILDING BONES(Have to have carbon and hydrogen) 

• Mature bone cells; CONTROLS release of CALCIUM from BONE to BLOOD

• RESPONSIBLE for secreting ACID leading to the EROSION of BONE(osteolysis) so the MINERALS can be TRANSPORTED

Three types of Bone Cells: Osteoblast

• RESPONSIBLE for secreting ACID leading to the EROSION of BONE(osteolysis) so the MINERALS can be TRANSPORTED

• Mature bone cells; CONTROLS release of CALCIUM from BONE to BLOOD

• Secrete the ORGANIC components RESPONSIBLE for BUILDING BONES(Have to have carbon and hydrogen) 

Three types of Bone Cells: Osteoclast

• Secrete the ORGANIC components RESPONSIBLE for BUILDING BONES(Have to have carbon and hydrogen)

• RESPONSIBLE for secreting ACID leading to the EROSION of BONE(osteolysis) so the MINERALS can be TRANSPORTED

• Mature bone cells; CONTROLS release of CALCIUM from BONE to BLOOD

TWO TYPES OF BONE

Choose two that define Cancellous Bone (Spongy Bone)

• -Open network called TRABECULAE 

• Osteons PRESENT 

• Found where Bone AREN’T Stressed HEAVILY or STRESS is BALANCED from ALL sides

• Osteocytes ARRANGED in CIRCULAR pattern around a HAVERSIAN canal where Blood vessels are PRESENT
