5.   The ANS almost always consists of __a__ (number) motor neurons.  The __b__ neuron runs from the CNS to a ganglion while the __c__ neuron runs from the ganglion to an effector.  Sympathetic __b__ neurons have cell bodies that originate in the __d__ gray horn from beneath the twelve __e__ vertebrae and first or second __f__ vertebrae.  Sympathetic __c__ neurons originate in __g__  ganglia that run parallel on either side of the vertebral column or in __h__ ganglia that are located anterior to the spinal cord close to abdominal arteries.  Parasympathetic __c__ neurons begin in __i__ ganglia and terminate on or within the effector.  
    Sympathetic __b__ neurons that reach a __g__ ganglion may follow one of 4 pathways.  First, the __b__ neuron may __j__ with a __c__ neuron in the __g__ganglion adjacent to its source of origin.  The __c__ nerve fiber will then pass out the __k__ (3 words) that leads into the __l__ nerve and ultimately goes to a(n) __m__ (peripheral/internal) effector.  Second, the __b__ nerve fiber may pass thru the adjacent __g__ ganglion and __n__ (ascend/descend/ascend or descend) to another __g__ ganglion and __j__ with a __c__ neuron.  The __c__ nerve fiber will then pass out the __k__ (3 words) that connects to the __l__ nerve and ultimately goes to a(n) __o__ (peripheral/internal) effector. Third, the __b__ nerve fiber passes thru the __g__ ganglion and becomes the __p__ nerve before synapsing in a  __h__ ganglion.  From the __h__ ganglion, the __c__ nerve fiber goes to a(n) __q__ (peripheral/internal) effector.  Finally, a small percentage of __b__ nerve fibers pass thru the __h__ ganglion without __j__ and directly innervate the __r__  (2 words).
