Cranial Nerves having only sensory functions
Olfactory Nerve
Optic Nerve
Middle meningeal layer
Arachnoid Mater
Tapered end of the spinal cord
conus medullaris

column
Motor to muscles of facial expressions
Facial nerve
Superior boundary of the spinal cord
foramen magnum
Cranial Nerve responsible for detecting odor
olfactory nerve
Neuron found in the ventral root of the spinal cord
efferent neuron
Safe to do a spinal tap
below L2
In Patellar reflex which muscle contracting
quadriceps femoris
What nerve carries the afferent and efferent impulses
L4
Slight and transient brain injury
concussion
traumatic injury that destroys brain tissue
contussion
total nonresponse to stimulation
CVA
May cause medulla to be wedged through foramen magnum by intracranial pressure
intracranial hemmorhage
Reversible CVA
TIA
Progressive degeneration of the brain with abnormal protein deposits
Alzheimer’s disease
Autoimmune disorder with extensive demyelination
multiple sclerosis
Loss of sensation
Paresthesia
Paralysis without atrophy
Spastic paralysis
Loss of motor function
Paralysis
traumatic flexion and/or extension of the neck
whiplash
Result of cord transection between T11 and L1
Paraplegia
Transient period of function loss following cord trauma
spinal shock
Result of permanent injury to cervical region of the cord
Quadriplegia
Paralysis to one side resulting from brain trauma
hemiplegia
Sympathetic or Parasympathetic:
