Vocab on Bone Structure and Bone Tissue
Question | Answer |
---|---|
Define stiffness | ratio of stress to strain in a loaded material - that is, the stress divided by the relative amount of change in the structure's shape |
What is compressive strength? | ability to resist pressing or squeezing force |
Define tensile strength | ability to resist pulling or stretching force |
Define porous | containing pores or cavities |
What is cortical bone? | compact mineralized connective tissue with low porosity that is found in the shafts of long bones |
What is trabecular bone? | less compact mineralized connective tissue with high porosity that is found in the ends of long bones and in the vertebrae |
Define strain | amount of deformation divided by the original length of the structure or by the original angular orientation of the structure |
What is the axial skeleton? | the skull, vertebrae, sternum, and ribs |
What is the appendicular skeleton? | bones composting the body appendages |
Define short bones | small, cubical skeletal structures, including the carpals and tarsals |
Define flat bones | skeletal structures that are largely flat in shape - for example, the scapula |
What are irregular bones? | skeletal structures of irregular shape - for example, the sacrum |
What are long bones? | skeletal structures consisting of a long shaft with bulbous ends - for example, the femur |
Define articular cartilage | protective layer of firm, flexible connective tissue over the articulating ends of long bones |
What is epiphysis? | growth center of a bonee that produces new bone tissue as part of the normal growth process until it closes during adolescence or early adulthood |
What is periosteum? | double-layered membrane covering bone; muscle tendons attach to the outside layer, and the internal layer is a site of osteoblast activity |
