Question	Answer
Where are somatic motor neuron cell bodies located?	anterior gray horn
How do somatic motor neurons leave the spinal cord?	through the ventral root
The specialized synapse between a nerve and a muscle is called the ___________________.	neuro muscular junction(NMJ)
The neurotransmitter for the neuro muscular junction(NMJ)is __________________.	acetylcholine(ACH)
What are the two divisions of the autonomic nervous system?	sympathetic(fight or flight) parasympathetic(rest and digest)
All autonomic pathways contain a __________________ neuron and a __________________ neuron except for one.	preganglionic; postganglionic
Preganglionic neurons are ____________________.	myelinated
Postganglionic neurons are __________________.	unmyelinated
The autonomic nervous system can be thought of as ______________ system because it has both preganglionic and postganglionic neurons, with the exception of one.	two neuron
Somatic motor neurons are part of the autnomic nervous system. True or False	False They are not part of the autonomic nervous system.
Postganglionic neurons are going to synapse with an ___________.	effector(muscles or glands)
Preganglionic neurons in the ______________ division are located in the lateral gray horns of the spinal cord.	sympathetic
The lateral gray horns are located in the ______________ segments and the first two ______________ segments of the spinal cord.	12 Thoracic(T1-T12); Lumbar(L1-L2)
Preganglionic neurons of the ________________ division are located within the four cranial nerve nuclei,______,_______,______,______, and the lateral gray horns of ____________________ segments of the spinal cord.	parasympathetic; Cranial nerve III, VII, IX, X; 2nd thru 4th Sacral(S2-S4)
Because the preganglionic neurons of the parasympathetic region are located in some of the cranial nerves and some of the sacral segments, the parasympathetic division is also known as _________________.	the craniosacral division
There are 2 sympathetic chains, one on each side of the _________________ and one just anterior to the vertebral column near the aorta.	spinal cord
The sympathetic chain located anterior to the vertebral column near the aorta is called ____________________.	prevertebral ganglia
List the two groups of sympathetic ganglia.	1)Sympathetic trunk ganglia 2)Prevertebral ganglia
The ______________________ ganglia innervates structures above the diaphragm.	sympathetic trunk
The ______________________ ganglia innervates structures below the diaphragm.	prevertebral
Preganglionic sympathetic neurons are _____________ than postganglionic neurons.	shorter
List the three important prevertebral ganglia(below the diaphragm).	-Celiac ganglion -Superior mesenteric ganglion -Inferior mesenteric ganglion
Preganglionic neurons do not have to synapse at the same level of the sympathetic chain ganglion it came out of. True or False	True Once preganglionic neurons come out onto the sympathetic chain, it may synapse anywhere on the sympathetic chain ganglion.
Preganglionic axons of the ___________________ division synapse with terminal ganglia.	parasympathetic
___________ ganglia are located close to or within the wall of a visceral organ.	Terminal
Preganglionic parasympathetic neurons are ___________ than preganglionic sympathetic neurons.	longer
Preganglionic parasympathetic neurons are longer than preganglionic sympathetic neurons because they have to stretch all the way from the CNS to a ___________________.	terminal ganglion
When preganglionic sympathetic axons exit the intervertebral foramen to get to the nearest sympathetic trunk ganglion, they pass through a short pathway called _____________.	white ramus
The white ramus is white becuase the preganglionic fibers that go through there are _________________.	myelinated
The gray ramus is gray because the postganglionic neuro fibers that go through there are ______________________.	unmyelinated
When the axons of postganglionic neurons leave the sympathetic trunk to merge with the anterior ramus of the spinal nerve, they pass through a short pathway called ___________.	gray ramus
Postganglionic sympathetic neurons release a transmitter called ___________________ except for one exception.	norepinephrine(NE)
All preganglionic neurons, in either the sympathetic or parasympathetic division, release the neurotransmitter _____________. (Cholinergic Neurons in the ANS that release ACH - 1 out of 3 Rules)	Acetylcholine(ACH)
Any neuron that releases ACH is called a ____________________.	cholinergic neuron
All parasympathetic postganglionic neurons release ______________. (Cholinergic Neurons in the ANS that release ACH - 1 out of 3 Rules)	Acetylcholine(ACH)
Sympathetic postganglionic neurons that innervate sweat glands release _____________. (Cholinergic Neurons in the ANS that release ACH - 1 out of 3 Rules) This is the one exception where a postganglionic sympathetic neurons do not release norepinephrin	Acetylcholine(ACH)
What are the two classes of cholinergic receptors?	-Nicotinic Receptors -Muscarinic Receptors

Any neuron that releases norepinephrine(NE) is called an _______________ neuron.	adrenergic
_____________ receptors will bind both norepinephrine(NE) and epinephrine(Epi).	adrenergic
What are the two classes of adrenergic receptors?	-Alpha -Beta
Neurotransmitter Rules(1 out of 6) All preganglionic neurons release __________________ as their transmitter.	Acetylcholine(ACH)
