What is ossification and resorption of the bone, and does it ever occur at the same rate? | Ossification is the formation of whole bone tissue. Resorption is the breaking down of bone by the osteoclasts . Then osteoclasts lay done new bone. |
Compare and contrast interstitial and appositional cartilage growth. | Both expand, bond, and secrete additional matrix during growth. The direction of growth differs as interstitial makes bones longer. |
How are homestasis, calcium ions, and bone connected? | Calcium ions have to be regulated closely in the blood as the osteoblasts helps make bone. The osteoclasts break bone down and release calcium into the blood. |
Name the functions of bones. | The functions are to support the body's framework, protect all of the inside structures, and provide movement. |
How does red bone marrow that starts at life (with yellow marrow) stay in the body if unlike yellow marrow, it's production? | Red bone marrow is founded during the life time in the ribs, parts of the vertebrae, humerous ends, the pelivs and the femur. Yellow |
What is a flexible tissue that is also firm and composed of mainly fibers of proteins? | Cartilage is a rubbery , flexible tissue of mostly protein fibers. It has few cells and cell types with little to no blood supply. |
Which bone makes a majority of the bone mass in an adult? | Compact bone is dense, looks solid, and makes up about 80% of the bone mass. |
How can you tell if a bone has grown to its full length? | The epiphyseal cartilage will dissapear due to bone replacing it. Then, the epiphysis and diaphysis will look continuous. |
What happens to the bone besides not being continuous as a result of a fracture? | Bone fractures create vascular damage by destroying blood vessels that supply nutrients to the bone's osteocytes. |
Explain what osseous tissue is. How it is different from other body tissues? | Ossesous tissue is bone tissue that is connective. It has cells, fibers, and extracellular material ( matrix). The matrix is calcified. |
