THE HUMAN SKULL
TYPES OF BONE STRUCTURE
LONG BONE
SHORT BONES
IRREGULAR BONES
FLAT BONES
FUNCTION OF THE SKELETON(BONE)
- support-for muscles, organs and soft tissues
- leverage and movement- the synovial joints
- protection- for critical organs
- calcium phosphate storage- mineral balance
- hemopoiesis- formation of blood cells
Classes of bones
- compact bone- dense and solid in appearance
- cancellous bone aka "spongy"- open space partially filled by needle like structures
MEDULLARY CAVITY: MARROW CAVITY OF A BONE
- Bone marrow is the flexible tissue in the anterior of bones.
- Bone marrow is the interior of bones. In humans red blood cells are produced by cores of bone marrow in the ends of long bones, as well as flat bones
- -production of red blood cells- hematopolesis
- Two types of marrow: red and yellow
- Red: epiphysis
- Yellow: diaphysis
