What are the functions of the Skeletal System? |
|
Definition
•Support (support for body, attachment for soft tissues)
•Storage of minerals (calcium and phosphate)
•Calcium most abundant mineral in body (~2–4 lb)
•98% stored in bones
•Blood cell production (all formed elements of blood)
•Protection (delicate tissues and organs surrounded by bone)
•Leverage (act as levers with skeletal muscles to move body) |

|
Definition
Gene mutation that causes bone deposition around skeletal muscles
•Bones developing in unusual places = heterotopic(hetero, place) or ectopic (ektos, outside) |
|
|
Term
