solutions
Osteoblast - ✔✔creates new bone; produces new bone tissue (osteoid) and mineralizes it
|| || || || || || || || || || || ||
Osteoclast - ✔✔resorb bone; major role in bone homeostasis
|| || || || || || || ||
Osteocyte - ✔✔matures bone cells; maintains bone tissue
|| || || || || || ||
Osteoid - ✔✔bone tissue
|| || ||
Spongy Bone - ✔✔cancellous bone; less complex and lacks haversian systems
|| || || || || || || || || ||
Compact Bone - ✔✔highly organized, solid, and extremely strong; basic structural unit in
|| || || || || || || || || || || || ||
compact bone is the haversian system
|| || || || ||
Number of Bones in Human Body - ✔✔206
|| || || || || || ||
Axial Skeleton - ✔✔consists of 80 bones that make up the skull, vertebral column, and thorax
|| || || || || || || || || || || || || || ||
Appendicular Skeleton - ✔✔consists of 126 bones that make up the upper and lower extremities,
|| || || || || || || || || || || || || || ||
the shoulder girdle (pectoral girdle), and the pelvic girdle (os coxae)
|| || || || || || || || || ||
Diaphysis - ✔✔narrow tubular midportion of a long bone
|| || || || || || || ||
Metaphysis - ✔✔broader neck region of a long bone that merges into the diaphysis
|| || || || || || || || || || || || ||
, 2
Epiphysis - ✔✔broad end of a long bone || || || || || || ||
Stages of Bone Fracture Repair - ✔✔Hematoma formation, Procallus formation, Callus
|| || || || || || || || || || ||
formation, Replacement, Remodeling || ||
Complete Fracture - ✔✔the bone is broken entirely
|| || || || || || ||
Incomplete Fracture - ✔✔the bone is damaged but is still in one piece
|| || || || || || || || || || || ||
Comminuted Fracture - ✔✔a bone breaks into more than two fragments
|| || || || || || || || || ||
Linear Fracture - ✔✔runs parallel to the long axis of the bone
|| || || || || || || || || || ||
Oblique Fracture - ✔✔occurs at a slanted angle to the shaft of the bone
|| || || || || || || || || || || || ||
Spiral Fracture - ✔✔encircles the bone
|| || || || ||
Traverse Fracture - ✔✔occurs straight across the bone
|| || || || || || ||
Pathologic Fracture - ✔✔break at the site of a preexisting abnormality, resulting from force that
|| || || || || || || || || || || || || || ||
would not fracture a normal bone
|| || || || ||
Fatigue Fracture - ✔✔caused by repetitive, sometimes abnormal stress or torque applied to a
|| || || || || || || || || || || || || ||
bone
Transchondral Fracture - ✔✔fragmentation and separation of a portion of the articular cartilage
|| || || || || || || || || || || ||
