What is epilepsy?
a disorder characterized by short, recurrent, periodic attacks of motor, sensory and psychologic malfunction
What initiates epilepsy attacks?
these attacks are initiated by abnormal, synchronous electrical discharges by numerous neurons in the brain which leads to seizures (i.e. uncontrolled nervous activity)
What causes epilepsy?
a wide variety of causes, ex. brain trauma, infection, metabolic disorders, etiology unknown, etc….
What is Quadriplegia?
paralysis of all limbs
What is Hemiplegia?
paralysis of one side of the body (e.g. upper limb, torso, lower limb)
What is Paraplegia?

What is Monoplegia?
paralysis of one limb
What is Transection?
severing of all or part of the spinal cord
What is Paralysis?
loss or impairment of motor function
What are first order neurons?
conducts the nervous impulse from the somatic sensory receptor to the CNS (Brain Stem or Spinal Cord)
What are 2nd order neurons?
conduct the nervous impulse from First Order Neurons to the Thalamus on the opposite side of the body
Where do the 2nd order neurons cross over?
these axons will cross over at the Spinal Cord or the Brain Stem
Where do the First and Second Order Neurons synapse?
in the Brain Stem or Spinal Cord
