Skeleton and function of bones Flashcards
What are bone cells called
osteocytes
what type of tissue is bone classified as
connective tissues
what are the main functions of skeletons
-support
-blood production
-protection
-storage of minerals
Skeletal divisions-Appendicular skeleton
includes the limbs and bony girdles
function of the appendicular skeleton
the bones enable the body to move.. Also protect some organs
Skeletal divisions-Axial skeleton
includes the skull, spinal column, ribs and sternum
Functions of the skeleton
support, movement, protection, mineral storage and blood production
functions of the skeleton-support
supports softer tissue and provides points of attachment for most skeletal muscles
functions of the skeleton-movement
muscles are attached to bones and when they contract, the bones will move
functions of the skeleton-protection
reduces the risk of injury by providing mechanical protection for the bodies organs
functions of the skeleton-mineral storage
bones store minerals, including calcium and phosphorous. Bones then release minerals into the blood when required
functions of the skeleton-blood production
red blood cells (erythrocytes) which carry oxygen and white blood cells (leucocytes) which protect against infection, are produced in the bone marrow of some bones
shape and function of long bones
-longer than wide
-Acts as levers; aid locomotion and support
shape and function of short bones
-equal dimensions
-absorbs impact
shape and function of flat bones
-strong, flat plates of bone
-protects organs; muscles attach to them
