epiphysis the end of a bone
false ribs rib pairs 8 - 10 connect to the vertebrae in the back but not to the sternum in the front
flat bones bones that are broad and thin with flat or curved surfaces such as the sternum
floating ribs rib pairs 11 and 12 free of any attachment in the front
fontanelle or fontanel soft spot
foramen hole in a bone through which blood vessels or nerves pass

hairline fracture a.k.a stress fracture
fracture broken bone sudden breaking of a bone
pathological fracture a bone which is weakened by a preexisting disease
closed reduction consists of aligning the bone fragments through manual manipulation or traction without making an incision into the skin
