27
Q

fasciculus gracilis function

A

carries information from lower limb and lower trunk

28

fasciculus gracilis and fasciculus cuneatus are in which column

A

dorsal column of white matter

30
Q

sits in tectorial notch

A

midbrain

31
Q

similarities in hematomas

A

Symptoms are caused by pressure on the brain, NOT anoxia
Both can be fatal if not properly tended to
Both are within layers of the dura`

32
Q

differences in hematomas

A 
Epidural = artery bleed (rapid)
Subdural = vein bleed (slow)

example of non-communicating hydrocephalus

A

Bulging of meninges in spinal cord/brain matter block flow -
Congenital narrowing of cerebral aqueduct,
spina bifida, TBI

ascending and descending sensory and motor

39
Q

lateral white matter column

A

ascending and descending sensory and motor

40
