| ___________ consists of a thin layer of cancellous bone sandwiched between two thin layers of _________. | Flat bones; compact bone |
| Which type of bones have no marrow cavity | Short bone Flat bone Irregular bone Sesamoid bone Sutural or Wormian bone |
| List one major function of flat bones | Protect vital body organs from injury E.g parietal bones in the skull protect the brain |
| Sesamoid bones are usually found wrapped within __________ that move over body surfaces | tendons |
| The sacrum is classified as an | irregular bone |
| The clavicle is classified as a | long bone |
| In long bones, hard dense compact bone is the thickest in the region of the ______ where the strength is needed | shaft |
| Long bones have enlarged ends called __________ and an elongated shaft called the _____________. | epiphyses; diaphysis |
| Sutural bones are strictly speaking | flat bones |
| In long bones, throughout the length of the shaft is the ___________ ________, which is lined with a tough membrane called the endosteum. | medullary canal |
| The medullary canal and the distal epiphysis of the humerus and femur contain ________ marrow, while the proximal epiphysis of these bones contains __________ marrow. | Yellow marrow; red marrow |
| red blood cells , platelets, and white blood cells are formed within the ______ marrow | the red marrow |
| The yellow marrow is made up mostly of _________ cells and _________ tissues. | Adipose/fat cells; connective tissues |
| Give five examples of flat bones | 1. Scapula 2. Ribs 3. Sternum 4. Skull bones 5. Pelvic bones |
| In long bones, the epiphyses are filled with __________ bone and covered with a thin layer of __________ bone | cancellous; compact |
| Cartilage does not have blood supply or nerve endings. True or false? | True |
| Both cancellous and compact bones will strengthen with exercise True or false | True |
| What is the periosteum? | Periosteum is the name given to the outer connective tissue that covers the entire length of the bone. Periosteum fibres and those of ligaments and tendons unite to connect bone to bone or muscle to bone. |
| Epiphyseal plates are the | growth plates that occurs at various locations at the epiphyses of long bones |
| What is the cortex? | It is the exterior layer of bones. It is dense and smooth and of varying thickness depending on the type of the bone, the interior core consists of networks of fibres (Trabeculae) that mesh with blood vessels and the bone marrow. |
| In long bones, most of the compact bone is found in the ____________, and cancellous bone is found in the ____________. | Diaphysis, epiphysis |
