Bones of varying shapes and sizes
Examples (vertebrae and certain bones of the skull or pelvis)
Flat bone do...? Examples?
Thin bones that protect certain organs,
Examples (most of the bones of the skull as well as the scapula)
Bones shaped somewhat like cubes that facilitate flexibility of the joints
Examples (wrist and ankle)
Two types of bone tissue and what do they have in common
Compact tissue and Cancellous tissue
They both contain living cells that help make repairs if a bone is broken or injured
The sponge like tissue inside bone
Examples: bone marrow stores fat/produces blood cells
Function of other bones
Protect/support organs make it possible to move.
Provide framework so that we can stand up and move
Bones store minerals that our body need to function properly
Produce blood cels
How do bones move
muscles move bones by pulling on them, cannot push, muscles come in pairs, one muscle pulls the bone one way, paired muscle pulls the other way
There types of bone connections
1. Rigidly connected
2. Joined by rubbery cartilage
3. Flexibly linked by muscular or ligamentous joints
Made up 80 bones in upper body
examples: skull, hyoid, vertebrae, ribs, sternum, arms and shoulders
bones in arms, shoulders, hips and legs.
Made up of libs or appendages, two arms and two legs, pelvis right and left shoulders.
Arms hang from shoulders and legs attached to hips.
Joints are kept together by (two things)
elastic straps called ligaments and a smooth flexible tissue called cartlage
