|
Preganglionic neuron
Location?
|
Spinal cord or the brainstem. The axon then travels out into the body, synapsing with the postganglionic neuron at an autonomic ganglion
|
|
Postganglionic neuron
Location?
|
The cell body of the postganglionic neuron resides in the autonomic ganglion, and its axon extends to the effector which it controls.
|
|
Acetylcholine
SMNS or ANS?
|
Neurotransmitter used in the somatic motor nervous system (SMNS)
|
|
Norepinephrine
SMNS or ANS?
|
Neurotransmitter used in the autonomic nervous system (ANS).
|

C - ANS Pathway
D - Postganglionic Pathway
E - Skeletal Muscle
F - Smooth Muscle
|
|
How many synapses are in an SMNS pathway between those two points?
|
There are no synapses between the spinal cord and the effector in the SMNS
|
|
How many synapses are in an ANS pathway between those points?
|
There is one synapse between the spinal cord and the effector in the ANS
|
|
Sympathetic division
Function?
|
Arouse the body
increases the rate and strength of the heartbeat and raises the blood pressure.
|
|
Parasympathetic division
Function?
|
"housekeeping” activities
slows the heart rate and lowers the blood pressure
|
|
Salivary glands
Location, Function
|
Mouth
produce saliva/digestion
|
|
Lacrimal glands
Location, Function
|
Eyes
produce tears
|
|
Arrector pili
Location, Function
|
Skin muscles
form goosebumps
|
|
Adrenal glands
Location, Function
|
Kidneys
produce and secrete epinephrine and norepinephrine
|
|
In which division are the autonomic ganglia close to the spinal cord?
|
In the sympathetic division, the autonomic ganglia are close to the spinal cord.
|
|
ANS pathway that extends from the spinal cord to the little finger. Is the ganglion of this pathway nearer to the finger or the spinal cord?
|
The ganglion is close to the spinal cord
