ch 7 bone tissue Flashcards
tissues and organs of the skeletal system
skeletal system
composed of
bones
cartilages
ligaments
skeletal system
cartilage
forerunner of most bones
* covers many joint surfaces of mature bone
skeletal system
ligaments
hold bones together at joints
skeletal system
tendons
attach muscle to bone
skeletal system
functions of the skeleton
- support
- protection
- movement
- electrolyte balance
- acid-base balance
- blood formation
functions of the skeleton
support
- limb bones and vertebrae support body
- jaw bones support teeth
- some bones support viscera
functions of the skeleton
protection
- of brain
- spinal cord
- heart
- lungs
- and more
functions of the skeleton
movement
- limb movements
- breathing
- other movements depend on bone
functions of the skeleton
electrolte balance
calcium and phosphate levels
functions of the skeleton
acid-base balance
buffers blood against large pH changes by altering phosphate and carbonate salt levels
functions of the skeleton
blood formation
red bone marrow is the cheif producer of blood cells
bones and osseous tissue
bone
(osseous tissue)
connective tissue with the matrix hardened by calcium phospahte and other minerals
bones and osseous tissue
mineralization or calcification
the hardening process of bone
bones and osseous tissue
individual bones (organs) consist of
- bone tissue
- bone marrow
- cartilage
- adipose tissue
- nervous tissue
- fibrous connective tissue
general features of bones
flat bones
- thin, curved plates
- protect soft organs
