What is a bone made of ? |
Bones are composed of several different tissues working together... - Osseous Tissue - Cartilage - Dense Connective Tissue - Epithelium - Adipose Tissue - Nervous Tissue |
|
Are their other aspects of bone that make up the Skeletal System? |
All of the bones and their cartilages, along with ligaments, and tendons, constitute the skeletal system. |
|
What are the functions of the Skeletal System? |
-Protects the most important internal organs (Brain and spine) - Assists in movement - Osseous Tissue stores and releases minerals, particularly calcium and phosphorus. -Red marrow within the bone produces Red Blood Cells. - Yellow marrow within the bone stores triglycerides(fat), a source of potential energy. |
|
What is calcium good for? |
-Building strong bones. -Helping the Nervous System and muscles. - Contracting muscle - Thinking |
|
Describe a long bone.
|
- Greater in length rather than width. - They have long attachment areas (broad) (Humerus) |
|
Describe the short bone. |
Nearly equal in length and width. (Carpal bone) |
|
Describe a flat bone.
|
- Thin & Flat (Sternum) |
|
Describe an Irregular bone. |
- Complex shapes (Vertebra) |
|
Describe a Sesamoid bone. |
- Shaped like a sesame seed. - Developed in body after one is born. - Housed within tendons and formed because of use. (Ballerina foot) - "Extra bones" |
|
Regions of the long bone and their location. |
-Diaphysis: The shaft. -Medullary cavity: Yellow fat inside the shaft. -2 Epiphysis: Proximal & Distal. -2 Metaphyses: Join diaphysis and epiphysis with epiphyseal plate, or line once growth stops. |
|
What are the Surface tissues ? |
Endosteum: INSIDE Periosteum: OUTSIDE They coat the bone. Example: When your running and get a shin splint, you tear the endosteum off the bone. |
|
What are the Perforating (Sharpey) Fibers? |
Fibers that penetrate into the matrix. |
