Bones are classified by | Shape, Internal tissue organization, Bone markings (surface features; marks) |
Long bones | Are long and thin |
Long bones examples | Are found in arms, legs, hands, feet, fingers, and toes |
Flat bones | Are thin with parallel surfaces |
Flat bones examples | Are found in the skull, sternum, ribs, and scapulae |
Sutural bones | Are small, irregular bones |
Sutural bones examples | Are found between the flat bones of the skull |
Irregular bones | Have complex shapes |
Irregular bones Examples | spinal vertebrae, pelvic bones |
Short bones | Are small and thick |
Short bones Examples | ankle and wrist bones |
Sesamoid bones | Are small and flat, they do not create a joint |
Sesamoid bones | Develop inside tendons near joints of knees, hands, and feet |
Bone Markings | Depressions or grooves Along bone surface |
Bone Markings | Projections Where tendons and ligaments attach At articulations with other bones |
Bone Markings | Tunnels Where blood and nerves enter bone |
Structure of a Long Bone | Diaphysis Epiphysis Metaphysis |
Diaphysis | The shaft A heavy wall of compact bone, or dense bone A central space called medullary (marrow) cavity |
Epiphysis | Wide part at each end Articulation with other bones Mostly spongy (cancellous) bone Covered with compact bone (cortex) Epiphyseal Plate Distal v/s proximal |
Metaphysis | Where diaphysis and epiphysis meet |
Epiphyseal Lines | When long bone stops growing, after puberty Epiphyseal cartilage disappears Is visible on X-rays as an epiphyseal line |
Mature Bones As long bone matures | Osteoclasts enlarge medullary (marrow) cavity Osteons form around blood vessels in compact bone |
Periosteum | Covers outer surfaces of bones |
Compact bone | Cortical, Matrix |
Compact bone | Very strong, dense and tough, hard Mineral deposits=Ca salt deposits Osteocytes (bone cells) within lacunae organized around blood vessel |
Endosteum | membrane that divides Compact bone from Yellow morrow |
Spongy bone | Honeycomb layer, lighter and slightly flexible |
Bone marrow | where new cells are constantly being produced for the blood=Hematopoesis In the middle of some bones is jelly-like |
Bone tissue is composed of | Matrix and the Cells |
Minerals: Wo thirds of bone matrix is | -calcium phosphate, Ca3(PO4)2 & Other: calcium salts and ions -One third of bone matrix is protein fibers (collagen |
Cells : There are four main types of cells. | Osteoblasts Osteocytes Osteoprogenitor cells Osteoclasts: Dissolve bone matrix and release stored minerals (osteolysis) |
Osteoblasts | Immature bone cells that form new bone |
Osteocytes | Mature bone cells that maintain the bone matrix |
Osteoprogenitor cells | Stem Cells that create other cells |
Osteoclasts | Dissolve bone matrix and release stored minerals (osteolysis) |
Skeletal system includes | Bones of the skeleton Cartilages, ligaments, and connective tissues |
Functions of the Skeletal System | Support Storage of minerals (calcium( Ca)) Storage of lipids (yellow marrow) Blood cell production -Hematopoesis (red marrow) Protection Movement |
