Ch 4: Skeletal System
Term | Definition |
---|---|
Absorption | Process of putting something into the blood for the first time |
Appendicular skeleton | Bones of the arms, legs, pectoral and pelvic girdles |
Appositional bone growth | Type of growth that occurs in all bones making them more massive (and able to handle stress) |
Axial skeleton | Bones of the head, neck and trunk |
Cancellous bone | Bone connective tissue with a spongy appearance, caused by trabecular; found in the end of long bones & in the middle of flat and irregular bones |
Chondrocyte | Cartilage cell that produces a cartilage matrix of proteoglycans and water. (cells in cartilage connective tissue) |
Comminuted | A fracture in which the bone is broken into 3 or more pieces (commonly referred to as shattered) |
Compact bone | Bone connective tissue arranged in a series of osteons found in the shafts of long bones and the surfaces of flat and irregular bones. |
Deposition | The process of putting calcium phosphate crystals into the bone |
Diaphysis | Shaft of a long bone (has a fibrous covering called periosteum and is a source of osteoblasts) |
Endochondral ossification | Process that forms long bones |
Epiphyseal plate | Cartilage between the epiphysis and diaphysis in an immature long bone |
Fontanelle | Membranous area between flat bones of the skull, eventually replaced by a suture (fibrous joint). Commonly called 'soft spot'. |
Foramen magnum | Opening found in occipital bone, allows spinal cord to exit the cranial cavity |
Hydroxyapatite | Calcium phosphate mineral salt that makes up the mineral matrix of bone connective tissue (make the matrix hard) |
Meniscus | Fibrocartilage pad in the knee between the femur and the tibia |
Osteons | Haverisan system. Target-like arrangement of bone connective tissue found in compact bone |
Reabsorption | The process of putting something into the blood again, not the first time |
Synovial membrane | Membrane lining the joint space of a synovial joint (soft tissue found between the articular capsule (joint capsule) and the joint cavity of synovial joints) |
Trabeculae | Sliver-like or plate-like arrangement of bone connective tissue found in cancellous bone (gives it a spongy appearance) |
