Linear fracture
Define linear fracture
Straight,
sharply defined
non-branching lines of the skull
curvelinear density in which the fracture edges overlap describes which fracture
depressed fracture
define depressed fracture
Skull fracture that is depressed inward
fracture of bones of the base of the skull that can involve the occipital bone, sphenoid, ethmoid or temporal bones.
Basilar skull fracture
- radiographic sign: air fluid level in sphenoid sinus or clouding of mastoid air cells

Basilar skull fracture
Which radiographic exam is crucial when there is a suspected basilar fracture
x-table skull
Damage to the brain that results from accerleration and rapid deceleration of the head is known as
closed head injury
aka: traumatic brain injury ( TBI )
Brief loss of unconsciousness which results in headache, vomiting and vertigo
Concussion
Define concussion

____ hematoma results from a torn artery with blood pulling between the skull and dura matter
epidural hematoma
___ follows blunt trauma. It is positioned between the dura matter and the arachnoid meningeal layers
subdural hematoma
___ oocurs at the vertex. It accumulates between the arachnoid layer and the pia matter
subarachnoid hematoma
