dura matter-outermost layer of meingi
Subdural Hematoma
blood collection b/t dura and the arachnoid membrane the second meningeal membrane
Craniotomy
a hole made in the skull to relieve pressure by draining accumulated blood
Cerebral concussion
-bruising of tissue from back and forthe movement of head insult
-or impact blunt object
disruption of normal electric activity but brain is not perm injured
Cerebral Contusion
more serious than concusion
bruising of tissue along or just underneath brain surface
perm damage may result
may be associated with skull fracture
CT Dx
Depressed Skull Fracture
break in cranium
can cause quadriplegia hemi or para
Hemiplegia
partial paralysis of half of body
casue can be fracture causeing pressure on motor area of brain

loss of nerve function below waist
paralysis of lower trunk and legs
Quadriplegia
C5 damage
paralysis arms hands etc
Degenerative Disk Disease
deterioration of intervertbral disk
intractable pain may result in some loss of motor function
misalignment of vertebrae cause spinal nerve root scarring
may cause spinal stenosis
spinal stenosis
nerve roots become trapped in the foramen as they leave the spinal canal
Herniated/ Bulging Disk
-ruptured slipped
-result from accumulated trama
nucleus pulposus

-physiological factors
1-strain on muscles of face neck scale - tension headache
2- edema within the bv of head which changed arterial size- vascualr headache
