Choose the best location for obtaining a red bone marrow sample from a patient.

• head of humerus

• frontal bone

• medullary cavity of femur

• hip bone

     Which of the following are correctly matched?    

• linear fracture; the break is perpendicular to the bone's long axis        

•   incomplete fracture; the bone is broken through        

•  nondisplaced fracture; the fractured bone ends are misaligned        

•  open (compound) fracture; the fractured bone ends penetrate the skin        

Cranial bones develop ________.

• True

• Flase

Which of the following is NOT a function of the skeletal system?

• communication

• storage of minerals

• support

Which structure allows the diaphysis of the bone to increase in length until early childhood?

• lacuna

• epiphyseal plate

• epiphyseal line

• osteon

For intramembranous ossification to take place, which of the following is necessary?
