Ultrasound is a safe procedure that uses ______________.
radiation
sound waves
dye
film
Which of the following scans does not use radiation?
MRI
CT scan
PET scan
X-ray
If a fracture is comminuted, that means the bone is in _______ pieces.
Multiple
One
What is happening in this stage of bone healing?
Bone is fractured, hematoma forms
Bony callus forms, osteoblast cells create new bone
Remodeling, osteoclasts remove extra bone until its completely healed
Fibrocartilage callus forms, chondroblast and fibroblasts produce the fibrocartilaginous calus
What type of fracture is this? (Hint: it's across the bone.)
Dorsal
Linear
Closed
Transverse
What type of fracture is this?
Transverse
Comminuted
Simple
Spiral
Cells that can build bony matrix.
Osteoblasts
Osteoclasts
Canaliculi
Lamellae
What is happening in this stage of bone healing?
Bone is fractured
Bony callus forms, osteoblast cells create new bone
Remodeling, osteoclasts remove extra bone until its completely healed
Connective tissue cells form a fibrocartilage callus . New capillaries begin to form in the damaged area.

Compound
What is the blood clot that first forms around a fracture?
Hematoma
Callus
Bone
In the fourth step of fracture healing this will occur
Fibrocartilaginous converts to bony callus
Bony callus formation
Bone remodeling
Mass or clot is forming
Where is the femoral median condyle?
(a)
Bones are considered alive.
True
False
What occurs in the third step of fracture healing?
Fibrocartilaginous converts to bony callus
Bone remodeling
Torn blood vessels hemorrhage
