| What type of tissue is Bone? | Connective Tissue |
| What tissues do bones contain? | Bones contain
- nervous tissue
- blood connective tissue
- cartilage is found w/in articular cartilages
- epithelial tissue lines the blood vessels |
| What does the bone marrow synthesize? | synthesis of new blood cells |
| What are the functions of the bones? | The bones provide the body with support
The bones allow for movement
the bones provide protection
the bones provide mineral storage
the bones allow for blood cell formation
the bones assist in energy metabolism |
| How do the bones function in support? | the bones provide a hard framework |
| How do the bones produce movement? | skeletal muscles use bones as levers |
| Why do the bones provide protection? | underlying organs require organs |
| Why do bones provide blood cell formation? | bone contains red bone marrow which is a site for the synthesis of new blood cells |
| How do bones function in energy metabolism? | Osteoblasts secrete osteocalcin |
| What are the two components found in bone tissue? | Organic and inorganic components? |
| What are considered the organic components of bone tissue? | -cells
- fibers
- ground substance |
| What are considered the inorganic components in bone tissue? | - mineral salts that invade and form part of the bony matrix |
| Describe the role of the organic components in regard to the extracellular matrix of bone tissue | the organic components only make up 35% of the bone matrix but they contribute to flexibility and tensile strength |
| Describe the role of the inorganic components in regard to the extracellular matrix of bone tissue | The inorganic components make up more than half of the bone matric and provide exceptional hardness allowing them to resist compression |
| Name the structure | Lamellae |
| Name the structure | Osteon |
| Name the structure | Central Canal |
| Name the structure | Osteocytes in Lacunae |
| Name the structure | Canaliculi in matrix |
| What are the 3 types of cells that are involved in bone production/maintence | - osteoblasts
- osteocytes
- osteoclasts |
| Function of osteoblasts | osteoblasts actively produce and secrete bone matrix |
| Where do osteoblasts arise from? | Osteogenic cells are stem cells that differentiate into osteoblasts so osteoblasts stem from osteogenic cells |
| Function of Osteocytes | osteocytes keep the bone matric healthy |
| Function of osteoclasts | osteoclasts secrete substances that break down bone |
| The bone matric is ____. | osteoid |
| Name the types of cells in regards to their function/definiton | Osteocyte - maintain bone tissue
Osteoblast- forms bone matrix
osteogenic cell- stem cell that becomes osteoblasts
osteoclast- reabsorbs bone |
| How are bones classified | Bones can be classified according to shape |
| Name the classification of bones | - long bones
- short bones
- flat bones
- irregular bones |
| what is an example of a long bone? | the humerus |
| What is an example of a flat bone? | the sternum |
| What is an example of a short bone? | Talus |
| What is an example of a irregular bone? | vertebra |
| classify the types of bones | 1. Long bone
2. flat bone
3. Short bone
4. irregular bone |
